“THE RADIANCE OF GOD’S GLORY”:

 RECOVERING THE DOCTRINE OF ETERNAL GENERATION FROM HEBREWS 1:2-3

By: Daniel McMillin

Abstract: This paper provides a biblical warrant for the doctrine of eternal generation from Hebrews 1:2-3. The doctrine of eternal generation is concerned with the ontological relation shared among the Father and Son. The Father eternally begets the Son, and the Son eternally proceeds from the Father. Eternal generation is an act according to the divine essence where God the Father communicates His eternal, immutable, impassible, and simple essence to His begotten Son.[1] John Webster has defined “eternal generation” as “the personal and eternal act of God the Father whereby he is the origin of the personal subsistence of God the Son, so communicating to the Son the one undivided essence.”[2] In this paper, I offer a dogmatic approach to Hebrews 1:2-3 that uncovers the doctrine of eternal generation through the Father-Son relationship  and the radiance and image analogy. I then argue that the Book of Hebrews frames as the backdrop for the Nicene Creed’s affirmation that the second person of the Trinity is “light from light. The doctrine of eternal generation within the Nicene tradition finds its roots in the biblical witness as the Son is described as “the radiance of the glory of God.” Finally, I suggest that the doctrine of eternal generation provides the proper framework for contemplating the divine identity of the Son in light of the Father-Son relationship.

A CHRISTOLOGY OF HEBREWS AS DIVINE IDENTITY

The high Christology of Hebrews portrays the person of Jesus as the eternal and incarnate Son who works as the eschatological Prophet, Priest, and King. As the book of Hebrews begins, the reader is introduced to the Son at the climax of salvation history. “In these last days, he has spoken to us by his Son. God ha appointed him heir of all things and made the universe through him. The Son is the radiance of God’s glory and the exact expression of his nature, sustain all things by his powerful word. After making purification for sins, he sat down at the right hand of the Majesty on high” (Heb. 1:2-3).[3] From the prologue, the Son is viewed as the ultimate revelation of God who explains the divine essence through His power to create, sustain, and save.

Donald Hagner observes, “Christology in Hebrews, as throughout the New Testament, consists in the identity of Jesus bound together with what he does. Very simply, it is because of who Christ is that he can do what he does. The unique emphases of the christology of Hebrews can be best appreciated by examining this connection between the person and work of Christ.”[4] The identity of Christ acts as the primal subject of Hebrews through which all of salvation-history is climactically unlocked. That is why the book of Hebrews focuses upon the Son of God as it begins at the climax of Jesus’ person and work where the Son’s humiliation on earth has come to an end, following His redemptive mission, and He is exalted by the Father to sit at His right hand to reign in heaven on His throne.[5] 

Richard Bauckham categorizes the Christology of the New Testament as a Christology of “divine identity.”[6] Bauckham roots his approach in the Second-Temple Jewish monotheism of the first century to understand how the New Testament authors understood the Son’s relationship with the divine identity. defines this as “the unique identity of the God of Israel is the category by means of which we can best grasp the way Jews of the period understand God.” Notably, many of the characteristics that describe “the uniqueness of the divine identity” are granted to the Son in Hebrews 1:2-3. He writes, “The one God is sole Creator of all things and that the one God is sole Ruler of all things. To this unique identity corresponds monolatry, the exclusive worship of the one and only God who is so characterized.”[7] The divine identity, then, is expressed through divine attributes, deeds, and dedication. In other words, the God of Israel is known by who He is, what He does, and how He is treated. Notably, the divine identity was not often extrapolated into philosophical discussions in Jewish circles to uncover the ontology of Israel’s God. According to Bauckham, “For Jewish monotheistic faith what was most important was who God is, rather than what divinity is.”[8] Thus, he understands Jesus and the God of Israel in terms of identity rather than nature. Throughout Hebrews, the author “attributes to Jesus Christ three main categories of identity—Son, Lord, High Priest—and that each of these categories requires both to share the unique identity of God and to share human identity with his fellow-humans. In each category, Hebrews portrays Jesus as both truly God and truly human, like his Father in every respect and like humans in every respect.”[9]

The book of Hebrews opens with the God of Israel who previously revealed Himself through the prophets and patriarchs and speaks by the Son today (Heb. 1:1-2). Amy Peeler highlights how the word θεὸς (“God”) in Hebrews is employed in three distinct ways: (1) God in relation the Son (Heb. 1:9; ; 2:17; 4:14; 5:5, 10; 9:14, 24; 12;2); (2) the Son identified as God (Heb. 1:8-9); and (3) multivalent reference to the Father and Son as God (Heb. 1:2, 10; 11:3). In sum, “the word theos can signify God the Father, the divine person in relationship with the Son and the Spirit.”[10] The majority of the time, the Father is the referent of theos. According to Barry Joslin, 67 out of the 68 times the word theos is employed by the author of Hebrews, the term refers to the Father.[11] Similarly, C. Kavin Rowe writes, “In the theology of Hebrews ‘God’ is not collapsed into ‘Son’ or ‘Jesus’ any more than it excludes them. That is to say, ‘God’ is sufficiently relational in its meaning to require of the reader nimbleness in thought, a movement between selfsameness and difference. To put it in terms of Hebrews, the Son can both be called theos and ‘have’ a theos.”[12] In this way, divinity is not reducible to sonship.

Note the author’s use of Psalm 44 in Hebrews 1:8-9, as he interprets this passage as an intra-trinitarian conversation among God the Father and Son which is directed “to the Son.” The Psalmist writes, “Your throne, O God, is forever and ever, and the scepter of your kingdom is a scepter of justice. You have loved righteousness and hated lawlessness; this is why God, your God, has anointed you with the oil of joy beyond your companions.” The Son is identified as God, yet it can be said that God belongs to Him as “your God.” The Son is not another God other than the God of Israel. Instead, Hebrews demonstrates from the Scripture that the Son’s ontology is defined by divinity where He not only possesses the divine name and attributes but experiences an intimate relation with God. All throughout the epistle to the Hebrews, the divinity of Jesus is affirmed, and the prologue captures this truth with great precision.[13]

“YOU ARE MY SON, TODAY I HAVE BEGOTTEN YOU”: DIVINE SONSHIP AND ETERNAL GENERATION

“SON OF GOD”

The title “son” implies a relation to the father through generation, distinct personhood as a son, and shared identity, authority, and status. Each of these elements are assumed by the writers of the Hebrew Bible and the New Testament when they not only apply this terminology to “sons,” in general, but in particular when they use it to describe the “Son of God.” In the first-century, the title “Son of God” was used in a variety of ways.[14] In Jewish material, the title “Son of God” was attributed to human beings, the nation of Israel, Davidic Messiah, and angelic beings.[15] In the Greco-Roman sources, many rulers and Caesars were deified such as Alexander the Great, Romulus, Augustus, Tiberius, Julius, and their successors.[16] 

The New Testament’s use of “Son of God” certainly draws upon the backdrop of Jewish and Greco-Roman material, but the primary source of this Christological title is indebted to Jesus and His self-identity as the Son of God narrated in the Gospels and the Old Testament. Martin Hengel asserts the title “Son of God,” as it is used in the New Testament, “has become an established, unalienable metaphor of Christan theology, expressing both the origin of Jesus in God’s being (i.e. his love for all creatures and his unique connection with God) and his true humanity.”[17] D.A. Carson categorizes the New Testament’s use of the Christological title “Son of God” in four ways.^[18] First, the New Testament uses a “catchall” to describe Jesus as the “Son of God.”^[19] Second, the New Testament depicts Jesus’ role as the promised Davidic king.^[20] Third, the New Testament describes Jesus as the “Son of God” to fulfill His role as the Isaianic Suffering Servant of the Lord and as the representative of Israel.^[21] Fourth, the New Testament employs the term “Son of God” to describe Jesus’ divine status.^[22] Larry Hurtado suggests the title “Son of God” in the New Testament “primarily expresses Jesus’s unique standing and intimate favor with God, and God’s direct involvement in Jesus’s redemptive work.”^[23] Similarly, Oscar Cullmann notes, “the designation ‘Son of God’ does make the Father-Son relationship between God and Christ a special and quite unique one.”[24] In this way, the unique sonship attributed to Jesus in the New Testament entails an intimate, indivisible relationship with the divine.

In the book of Hebrews, the title υἱός (“Son”) is used eight times to describe Jesus as the divine Son (Heb. 1:2, 5, 8; 3:6; 4:14; 5:5, 8; 7:3, 28; 10:29) and three times to describe God’s children as the spiritually adopted “sons” (Heb. 2:10 12:5, 8).[25] In Hebrews 1:2-3, the author portrays the Son’s divine speech, status, and substance. In verses 5-13, the author of Hebrews draws His understanding of divine sonship from Samuel (2 Sam. 2:7) and the Psalms (Ps. 2:7; 95:6-7; 97:7; 110:1). These passages describe the honorific designation and royal exaltation of the Son, intimate relation between the Father and Son, superiority over angelic beings, reverent praise reserved for God, sovereign dominion over all creation, and moral divine perfection.[26] R.B. Jamieson observes “the Epistle to the Hebrews uses the title ‘Son’ to say of Jesus something that never has been and never could be said to one who is merely a man.”[27] The declaration of the proper name “Son” is distinctly attributed to a being that is divine. This title accomplishes three things: (1) “designates Jesus’ distinct mode of divine existence,” (2) “identifies the ‘Son’ as God,” and (3) “distinguishes him from, and relates him to, the Father and the Spirit.” In this way, “Hebrews’ grammar of divinity is implicitly trinitarian.”[28] 

Significantly, the author of Hebrews does not initially identify Jesus as the eternal Son (Heb. 1:2, 8) until Hebrews 2:9.[29] This careful consideration of Jesus as the Son is meant to highlight the priority of this title and His divinity in the opening of his sermon before he engages with His humanity, which is when the author eventually unmasks the identity of the divine Son as the man named “Jesus.” Notably, it is not the author who directly identifies Jesus as the Son but God Himself.[30] The intentionality of God identifying Jesus as the Son is understandable since it is the Father who declares the name of His begotten Son (Heb. 1:5).

The completion of the Son’s redemptive work on earth climactically leads to His exaltation, coronation, and vindication. “The one who has eternally been God’s Son—Creator, sustainer, radiance of the Father’s glory—now, at a moment in history, has become superior to angels and inherited the name ‘Son’ at his exaltation (his resurrection, ascension, and heavenly enthronement).”[31] It is not as though the Son was not always the Son nor is it the case that God was not always God. Instead, following His humiliation (Heb. 2:5-18), His glory is returned to Him at His exaltation. Thus, when the Son ascends to His throne, the Father declares “You are my Son; today I have become your Father” (Heb. 1:5; cf. Ps. 2:7).

THE ETERNAL SON

Contrary to Arius’ controversial assertion, “There was a time when the Son was not,” Hebrews shows there was never a time when the Son was not.[32] The eternal Sonship of Christ is demonstrated in three ways. First, the preexistence of the divine Son is implied by His agency in creation as the Creator and His possession of the divine nature (Heb. 1:1-8). Second, His existence prior to His saving mission in the incarnation (Heb. 2:9, 17; 9:26; 10:5). Third, the attributes of divine eternality and immutability belong to God’s Son (Heb. 1:12; 7:3, 16, 24; 13:8).[33] It is, therefore, safe to conclude that Hebrews’ Christology presents Jesus as the eternal Son of God. As Brandon Crowe contends, “Hebrews speaks of Christ as the eternal Son of God, who become incarnate for our salvation and fulfills the role of great high priest.”[34] In this regard, divine sonship is not strictly an incarnational title in the New Testament, and it certainly is not in Hebrews. Rather, it is a designation granted to Jesus because He is the Son from all eternity who shared in our humanity. In fact, as Francis Turretin suggests, “he could not have exhibited to us by incarnation the glory of God and the mark of his person unless he had been such before by an eternal generation.”[35] Charles Lee Irons similarly argues that while “the title ‘Son” in Hebrews can sometimes be interpreted as the incarnate Son, the relative clauses do not focus on the Son as incarnate, but on the pre-incarnate Son who existed before creation.”[36]

“The divine Son in Hebrews,” Bauckham suggests, “is Son of God from all eternity as well as to all eternity: sonship is the eternal truth of his very being, not simply a role or status given him by God at some point.”[37] Hebrews’ sonship entails an intimate relationship between God the Father and Son as they share the same divine essence as coeternal and consubstantial persons.[38] The title “Son” identifies Jesus as a divine person but also distinguishes one person from another.[39] In Hebrews, it reveals the relation of the Father and the Son along with His eternal generation as the Father is seen as the begetter and the Son is the one begotten. As Thomas Schreiner notes:

“The relationship between the Father and the Son is explicated analogically in terms of the relationship between fathers and sons among human beings, which points to the personal relationship that exists between the Father and the Son. We have here the textual evidence that eventuates in the notion that there are different persons, and yet they share the same essence or nature. The Son is no less than the Father, and yet he is distinct from the Father and the Son.”[40]

This Christological title envisions the eternal and incarnate sonship of Christ and can be understood in terms of His humanity and divinity.[41] The primary function in Hebrews, however, is on the divine ontology of the Son where the use of “Son of God,” understood in reference to Christ’s humanity, is subservient to the reality of His eternal sonship which is located in His divinity.  Divine sonship entails all of the “Godness” of the Son. In other words, the divine essence is associated with the Son because of the divine attributes, actions, titles, and praise.[42] As Joslin writes, “The whole exordium magnifies the excellence of the Son.” As such, “it seems apparent that the writer understands the Son to share the same essence with the deity. Both ontological and economic aspects are crucial, and without them, the homily itself loses its force.”[43]

Herman Bavinck argues the logic of these familial terms when applied to the divine persons only make sense if it points to His eternal nature and procession. He proposes that a rejection of the Son’s eternal generation is an afront to the Father’s eternal nature. “If the Son is not eternal, then of course God is not the eternal Father either. In that case he was God before he was Father, and only later—in time—became Father. Hence, rejection of the eternal generation of the Son involves not only a failure to do justice to the deity of the Son, but also to that of the Father.” In addition, this makes God mutable, finite, and temporal. It is for that reason, “we must, accordingly, conceive that generation as being eternal in the true sense of the word. It is not something that was completed and finished at some point in eternity, but an eternal unchanging act of God, at once always complete and eternally ongoing. Just as it is natural for the sun to shine and for a spring to pour out water, so it is natural for the Father to generate the Son.”[44]

ETERNAL GENERATION

The church fathers often located the doctrine of eternal generation in the nature of sonship. However, modern interpreters are hesitant to concede this point by ignoring the theological implications of the Son being begotten by God the Father. For example, Harold Attridge suggested, “The degree of commitment to an ‘ontological’ understanding of divine ‘Sonship’ remains unclear. The affirmations about the status of Jesus, although rhetorically ornate, nonetheless leave room for speculating on what the relationship between Jesus and the Father might be.”[45] To best account for this space left unoccupied, we will uncover the theological implications of divine sonship in Hebrews 1:2-3.

In Hebrews, the introduction to the eternal generation of the Son is seen in view of divine sonship. God affirms His divine identity by “naming the Son, asserting God the Father’s own role in begetting, then explicitly affirming his identity as Father and Jesus’s as Son.”[46] The logic of sonship entails begottenness from the father as the source.[47]  A “father” fathers his “son.” As Sanders suggests, “The Father gives his Son: that is to say that the Father who fathers the Son, gives the Son, who is passively sonned by the Father who actively fathers him.”[48] A father is not a father without a son, and a son is not a son without a father. Likewise, God the Father cannot be ascribed fatherhood without the Son and God the Son cannot be identified by His sonship without the Father.[49] For the New Testament’s inclusion of the personal names to be coherent, there must be a sense in which God can be properly called “Father” and “Son,” otherwise these names are nonsensical. As Augustine suggests, “Because the Father is not called the Father except in that he has a Son, and the Son is  not called Son except in that he has a Father, these things are not said according to substance; because each of them is not so called in relation to himself, but the terms are used reciprocally and in relation each to the other.”[50]

Scott Swain notes three interpretive lenses for understanding the Father-Son relation in regard to the doctrine of eternal generation. First, the binitarian shape of the text is in view as “two relatives” are described, namely, “God” the Father and “his Son.” Second, the operations of the Son reveal the Father, that is, when the “activity of one agent” displays the “relationship between the two relatives: the Father is glorious; the Son is the effulgence of the Father’s glory shining forth.” Third, the identical divine identity describes “the nature of the similarity that obtains between these two relatives” as everything that belongs to the Father also belongs to the Son since He is “the exact expression of his nature.”[51] The personal names, according to Swain, “signify relations” and “character the Father-Son relation.” Within a Trinitarian framework, “The Father is Father to the Son (‘paternity’ is thus his unique personal property); the Son is Son to the Father (‘filiation’ is thus his unique personal property); the Spirit is the Spirit of the Father and the Son (‘spiration’ is thus his unique personal property). These personal properties are not interchangeable.”[52] In this way, the Father is not the Father if the Son is not eternally begotten or generated from the Father.

These personal names, “father” and “son,” convey familial relations since a father always begets a son and a son is always the son of a father.[53] These are “relative” terms that “signify” a genuine “relation” that is only experienced by father and son. According to Jamieson and Wittman, “The terms ‘father’ and ‘son’ refer to a subject not simply as that subject is in itself but only as that subject exists in relation to another. Similarly, in Scripture, when used as titles that identify who Jesus and his heavenly Father are intrinsically, the terms ‘Father’ and ‘Son’ are not absolute elative.”[54] In this sense, the personhood of the Father and Son showcase their distinction and relation. The term “Father” often “names one divine person as the source of another” and the “Son,” likewise, “names one as begotten from the other.” These terms point to “kinship names are reciprocal and point us to a relation of origin.”[55] Within this viewpoint, God is the Father who fathers or begets the Son eternally.[56] 

The eternal relations of origin are the foundation for contemplating the unity and distinction among the divine persons of the Trinity.[57] The Father’s paternity is established by His relation to the Son by begetting Him and the Son’s sonship is grounded in His relation with the Father as He is begotten by the Father. This is why God has revealed Himself as Father and Son so we may grasp the unity and distinction among the three persons who share the one divine essence. Daniel Treier noted, “Eternal generation identifies Father and Son as proper names for these divine persons, specifying their relations of origin and modes of subsistence in what human beings cannot help but perceive as metaphorical terms.”[58] The personal names of God are intentional as they reveal the eternal relations of origin. Notice how the Triune persons are distinguished in familial terms in reference to the first and second person, yet without any analogical relation with the third person. The Father’s paternity is seen as He begets the Son but the Spirit does not possess a similar familial analogy. This is why the Scriptures do not describe the triune persons as “three brothers” but as Father, Son, and Spirit.[59]  The function of eternal generation is to account for the best explanation for these biblical metaphors that distinguish the divine persons and describe the divine relations in familial terms.[60]

When the author of Hebrews cites the Psalmist, He suggests that the angels never were told, “You are my Son; today I have begotten you” (Heb. 1:5, NASB). But this passage also assumes that this was a conversation between two divine figures identified as “Father” and “Son” that can be overheard through the Scriptures. When the Son is said to be “begotten” by the Father, there are two areas of clarification required: (1) the nature of divine generation, and (2) the implications of eternal generation.

Begotten from the Father

First, the translation of γεγέννηκά unambiguously refers to generation and is accurately rendered “begotten.” Jesus is not merely the one and only unique Son of the Father, but He is sent forth from the Father as the Son. The nature of generation relays a relation of origin that is understood through a familial relationship. When it is said that He is “begotten” by God and granted the title “Son,” the author views this as an eternal association among God the Father and Son. This relationship is then understood in terms of the Father begetting the Son eternally.[61]

Additionally, “To speak of the eternal generation of the Son is to speak of what is proper to the Son of God: he is begotten.” Generation entails the Sons’ reception of “his personal subsistence from the Father.”[62] To be begotten does not mean to be created but is a manner of locating the origin of Son’s divinity “from the Father’s nature.”[63] John of Damascus defines “begetting” as the “producing of the substance of the begetter an offspring similar in substance to the begetter” whereas creation is “bringing into being, from the outside and not from the substance of the creator, of something created and made entirely dissimilar.”[64] Divine sonship does not entail creation but excludes it. As Athanasius wrote, “If then son, therefore not creature; if creature, not son.”[65] The Son is not created by the Father, otherwise He would be unlike the Father. Instead, He is generated by the Father and receives His essence and likeness. Thus, to be begotten, refers to the Son’s sameness and substance with the Father.[66] As Jamieson says, “What God does, Jesus does; what God is, Jesus is.”[67] 

The eternal generation of the Son is analogous and disanalogous to human generation.[68] The Son’s generation is unlike human generation in that His sonship is essential but does not require a mother nor does it imply inferiority in rank, role, or ontology.[69] However, it is similar in that the father-son relation necessarily includes one who begets and one who is begotten. The relationship between any father and son is generation as the father begets but does not create his son. As Swain notes, “The relation between the Father and the Son is a relation between divine person, not between a divine producer and a creaturely product.”[70] Athanasius regarded the Son as the “offspring” of the Father who is begotten by the Father in a manner that is unlike the created order. “He is not a creature or work, but an offspring proper to the Father’s essence.”[71] For the Father to beget the Son entails the communication of the Father’s nature. John of Damascus suggests the “producing of the substance of the begetter an offspring similar in substance to the begetter.”[72] When the Son is begotten by the Father, He does not produce something dissimilar to Himself. As Hilary of Poitiers pointed out, “Proceeding forth of God from God is a thing entirely different from the coming into existence of a new substance.”[73] He suggests, the Son “cannot come into existence as other than God, since His origin is from none other than God.” To be begotten entails sameness between the subject begotten with the one who does the begetting. That is why he suggests, “His nature is the same, not in the sense that the Begetter also was begotten—for then the Unbegotten, having been begotten, would not be Himself—but that the substance of the Begotten consists in all those elements which are summed up in the substance of the Begetter, Who is His only Origin.”[74] Thus, “the Son is,” as Glenn Butner comments, “uniquely and eternally related to the Father by way of generation.”[75]

Eternal Today

Second, the “today” in reference is not to any specific moment in time but to the ever abiding mutual indwelling and procession of the Son from the Father. Madison Pierce shows how the author of Hebrews’ use of the word “today” is not intended to refer to a certain day but to the present by comparing Heb. 1:5, 3:13, and 13:8. She concludes that “the author draws upon the relative dimension of the word ‘today,’ which is always in the present, so that the words of the psalm and his subsequent exhortations are valid forever.”[76] In other words, “today” is an eternal day.  There is no established birthday for the generation of the Son because it is not confined to the limitation of time. As Augustine says, the term “today” here “denotes the actual present, and as an eternity nothing is passed as if it had ceased to be, nor future as if it had not yet come to pass, but all is simply present, since whatever is eternal is ever in being, the words, ‘Today I have begotten you,’ are to be understood of the divine generation.”[77] 

During the Arian controversy, when the inception of the Nicene Trinitariansim took shape, the Nicene fathers and the Arians differed on their perspective of divine Christology, but both sides agreed that the Son of God was begotten or generated by the Father. The issue debated among these theologians was the nature of this generation. The Arians argued that since the Son was begotten, then He was created. “It is more pious and more accurate to signify God from the Son and call Him Father, than to name Him from His works only and call Him Unoriginate.”[78] However, the Nicene fathers set Christ apart from creation categorically when describing His eternal relations of origin by clarifying the Son was “begotten, not made.” Macleod notes, “There is a clear distinction between being begotten and being made. What is begotten is a Son, what is made is a creature.”[79] The Arians interpreted generation as a temporal act of creation whereas the Nicene fathers suggested generation as an eternal relation.[80] In other words, the generation of the Son was understood, not in terms relative to time, but was viewed as an eternal act ad intra. As Brandon Crowe notes, “The generation of the Son could not happen at a moment in time, for if it did, then the Son would not be eternally the Son—nor would the Father be eternal the Father.”[81] The Son’s generation is, therefore, not to be perceived as something temporal but eternal. Rather, the eternality of the Son’s generation is rooted in the divine atemporality of the Father.[82] Gregory of Nyssa highlights, “The generation of the Son is not within time, any more than the creation was before time. It is utterly wrong to introduce division into an order of existence that admits no separation and to interpolate an interval of time into the creative cause of the universe by asserting that there was a time when the author of existence did not exist.”[83] This is because the Son “exists by generation indeed, but nevertheless He never begins to exist.”[84]

“THE SON IS THE RADIANCE OF GOD’S GLORY”: DIVINE ANALOGY AND ETERNAL GENERATION

THE RADIANCE OF DIVINE GLORY

The hapax legomenon ἀπαύγασμα is either translated as “radiance,” “outshining,” or “reflection.” The difficulty of translating this term is due to its rarity in the New Testament and whether or not the term possesses an active or passive voice. In the active voice, the word ἀπαύγασμα is either translated as “radiance” or “effulgence” which speaks to light radiating from a source of light. In the passive voice, the term is often translated as “reflection” which refers to brightness shining back on the source of light (BDAG). Both translations are respectable and well attested. Ellingworth notes “the Greek fathers preferred the active meaning,” that is, “radiance,” whereas the “majority of modern commenters prefer the passive meaning,” that is, “reflection.”[85] It is possible to resolve these translation options as something synonymous (TDNT), but “radiance” is a preferable rendering in Hebrews.

If the phrase is translated as “radiance” and understood actively then this would correspond with the concept of “imprint” as “a grammatically active radiating or shing forth.” An alternative translation is “reflection” which is regarded as something passive where the idea of “imprint” then “receives an impression or light.” Steven Duby outlines the implications of these two options: “either the Son is the radiance of light that comes forth from the Father and therefore reflects the Father, or the Son reflects the Father and must therefore receive the light of the Father and thus go forth from him.”[86] Regardless of how one chooses to translate this term, it does point to the Son’s eternal relation from the Father and the brilliance of His glory.

However, these alternative translations relay similar yet divergent implications. The difference between “radiance” (active) and “reflection” (passive) is the difference between the radiant beams of sun and the reflection of light beams from the moon.[87] Alternatively, a shadow may reflect an image while indirectly connected to the light source while sun beams shines from the sun because it is directly connected to the light source.[88] Just as the radiance of sun displays the rays of light from the sun, the Son of God displays the essence of God. That is why, arguably, the preferred translation is “radiance” or “effulgence” as it emphasizes the Son’s connection to the Father as the source. As Tipton suggests, “The active sense does convey more appropriately the fullness of deity, in the form of glory, present in the Son. The Son need not reflect glory, because glory resides in him and flows from him as the eternal Son.”[89] In this sense, the Son is identified as the light but is also one who radiates from God the Father who is light itself.

The determining factor of this translation is based on whether or not this is a reference to the eternal or incarnate Son. When applied to the Son as the ἀπαύγασμα of divine glory, “reflection” relates to “the glory of God manifested in the perfection of Christ’s manhood (i.e., in his incarnation).” Whereas “radiance” refers “to the Son’s glory in his preexistent stage,” that is, prior to His incarnation in eternity.[90] The surrounding descriptors in Hebrews 1:2-3 narrate the Triune God’s activity in the economy as the Revealer (“he has spoken to us by his Son”), Creator (“made the universe through him”), Sustainer (“sustaining all things by his powerful word”), Redeemer (“making purification for sins”), and Ruler (“he sat down at the right hand of the Majesty on high”) of all things. Yet, the phrase ὃς ὢν ἀπαύγασμα τῆς δόξης καὶ χαρακτὴρ τῆς ὑποστάσεως αὐτοῦ (“the Son is the radiance of God’s glory and the exact expression of his nature”) stands out as it demonstrates how the incarnate Son can reveal the glory of God by appealing to His ontology. In other words, the reason why the Son can unveil the unique glory of God in the economy is that He possesses the same divine nature and, therefore, shines forth the essence of God as God.   

As the author of Hebrews describes the work of the Son in the economy, this unlocks truths of His divine ontology. His identification with the God of Israel is demonstrated by His unique inclusion in the divine identity.[91] The divine nature is discerned by the divine attributes as the Son is viewed as a sovereign, eternal, and glorious being which is expressed by His external works (ad extra) in salvation history. In other words, when the Son acts as the Agent of creation, the Sustainer of the universe, the great High Priest, the heavenly King, and the final Prophet of God, these acts of God are seen in the economy, but they reveal something true about God’s essence. As the incarnate Son dwells in our midst as “the radiance of God’s glory and the exact expression of his nature,” He shows the immanent and eternal Trinity in the economy.

Here, the Son is identified as the “manifestation” of divine glory.[92] He is capable of “out shinning” the glory of God by displaying who God truly is because He possesses the divine identity.[93] As Lightfoot said, “The Son radiates the ineffable light of the divine glory…Jesus Christ is the perfect shining forth and reflection of God among men.”[94] When Christ is seen, God is revealed. The glory of the Father is the glory of the Son. As Macleod states, “He is the glory made visible: not a different glory from the Father’s but the same glory in another form. The Father is the glory hidden: the Son is the glory revealed. The Son is the Father repeated, but in a different way.”[95] When the Son reveals God, He does not radiate the divine essence as the Father but as the Son. Instead, the Son shines forth the glory of God the Father as the Son.

The Son is necessary for the glory of God the Father to shine just as radiance is necessary for the sun to shine. “A light without radiance is not merely a deficient light, but not a light at all; it belongs to the very nature of light to be radiant, and its luminous emanation is thus integral to its very being.”[96] Returning to the analogy, the Father and the Son are indivisible in their relation and revelation as light from light. The sun is the source of light and the beams radiate the light. Furthermore, “light and brightness can be distinguished, but they cannot be separated.”[97] This is because the source and radiance are inseparably ascribed the nature of light. The light that is a source can be distinguished from the light that radiates, yet to divide the source from the radiance is to generate confusion because the two are indivisible and interdependent because they are ontologically one in essence. But distinguishing light from light does not divide the nature of light; it simply reveals their inseparability. “Truly the light and the radiance are one, and one is manifested in the other.”[98] As Athanasius said, “For what the light enlightens, that the radiance irradiates; and what the radiance irradiates, from the light is its enlightenment. So when the Son is held so is the Father for he is the Father’s radiance; and thus the Father and Son are one.”[99] 

Divine simplicity allows us to distinguish between the divine persons even though they are ontologically inseparable. Swain comments, “While the persons of the Father and the Son are truly distinct, their distinction does not constitute a division in God’s simple being.”[100] This is comparable to segregating the experience of brightness of the light from the perception of the light itself.[101] The difficulty arises due to the intimate association, which is seen when the Son of God radiates the glory of the Father. In the prologue, the author of Hebrews carefully associates the Son with His Father as the brightness He radiates points back to the source of generation. Thus, as Swain notes, “the Son is here identified as the Father’s glory shining forth, as the divine filial brightness of the divine paternal light.”[102] Rather than creating a division within the substance of light, it is more appropriate to view this light from light language as something that clarifies the distinction and unity between the source and the effulgence of light. “Light produces light, and the light that comes from light is somehow distinct therefrom. Yet the two are one single thing: light.”[103]

The significance of the Son as the “radiance of God’s glory” is that He reveals who God is so those whom He shines upon may be enlightened and experience the Father’s glory. As Origen said, “It is through its brightness that the nature of the light itself is known and experienced.”[104] The analogy of brightness illustrates how the Son possesses “the same nature as the Father.” Just like the radiance that shines from the flames has the nature of the fire. Likewise, the Son as the radiance of God is coeternal and consubstantial with the Father.[105] “There was never a time when he existed as a solitary God without his Son, so he was always God the Father…if Jesus is God the Son, God must always have included Son and Father.”[106] In this way, the Father and Son are inseparable from one another. The sun is never without its rays of brightness and the radiance of the sun is never without the source of light, likewise the Father is never without the Son and the Son is never without the Father.[107] As Gregory of Nyssa illustrated, “As the light from the lamp is of the nature of that which sheds the brightness, and is united with it (for as soon as the lamp appears the light that comes from it shines out simultaneously), so in this place the Apostle would have us consider both that the Son is of the Father, and that the Father is never without the Son; for it is impossible that glory should be without radiance, as it is impossible that the lamp should be without brightness.”[108]

ILLUMINATING DIVINE GLORY AND BRILLIANCE

Glory is “an essential attribute of God” and “the Son perfectly radiates God’s own glory.”[109] The object being radiated by the Son is the divine nature itself. That is why it can be said that the Son is the effulgence of the divine glory exhibited in God. It is because everything found within Him is the splendor and majesty of divinity. “The brightness of His glory,” Gregory of Nyssa clarifies, is “the brightness coming from the glory, and not, reversely, the glory from the brightness.”[110] Lightfoot rightly notes that this refers to “his eternal essence” prior to His incarnation since “there was a time when God was without a world, but there never was a time when He was without glory.”[111] The glory of God is eternal, it is not something that entered into time and began at some point in salvation history. Rather, the glory of God has descended into the person of Christ at the incarnation where “God’s glory is revealed in the Son.”[112] The eternality of glory that belongs to the Father corresponds to the eternality of the glory radiated by the Son.[113] As such, the divinity of Christ is demonstrated explicitly when the glory of God is attributed to the eternal and exalted Son.[114] The Son is the radiance of divinity as the sun is the radiance of light.

The Father and Son share the divine glory. As Amy Peeler notes, “It raises little contention to assert that the author of Hebrews presents the Father and the Eternal Son as sharing the same glory.”[115] The Christology of Hebrews presents God the Son as “a faithful representation of God’s glory.” This is because “the Son is the outpouring of God’s glory, which indicates it is the same glory of the Father.”[116] The glory that belongs to the Son is not different from the source of light, the Father, since it radiates from the Father through the Son. Peeler goes on to say, “The divine Son replicates the central core of who God is. If God the Father has glory the Son radiates it because he has the same nature.”[117] Thus, the divinity of the Son is highlighted since it is only possible for the Son to shine forth the glory of God if He truly is God. In other words, the Son can radiate the glory of God because He is God. As such, the Father and the Son share the same divine ontology and glory. Throughout the book of Hebrews, the Son will be directly linked with the divine name, glory, power, will, and throne since He shares the same essence with the Father.[118] As Hughes suggests, “The glory of the Son is identical with the glory of God the Father. Being divine, it transcends every glory of the created realm.”[119]

The “glory” reserved for the divine radiates from God’s Son. This is an allusion to Isaiah 42:8, which describes the God of Israel’s unique glory. “I am the Lord. That is my name, and I will not give my glory to another or my praise to idols.” Here, Yahweh alone is associated with glory and is worthy of dedication. If God’s glory was attributed to idols or praise was rendered unto these false gods, then this would be a misappropriation of the divine identity. Yet, when the New Testament authors, including the writer of Hebrews, identify Jesus as the eternal Son who radiates this unique glory, they do not find it necessary to offer any explanation or justification for granting glory to the Son that is reserved for Yahweh. This is because the New Testament authors recognize the Son’s divine identity—the glory reserved for Yahweh belongs to Jesus. “The effulgence of the glory of the Lord God, which will not be shared with another, is essential to the identity of the eternal Son of God.”[120]

ETERNAL GENERATION

Many modern interpretations of Hebrews 1:2-3 often gloss over the implications of the Son’s radiance and generation. Within biblical studies, various commentaries, the rigorous grammatical and historical outworking is present but the theological and dogmatic details are neglected.[121] Additionally, many systematic theologians disregard or forfeit eternal generation when they survey the Scriptures and conceded that the vast majority of patristic, medieval, and reformed theologians prior to the 18^th century upheld this doctrine on historical and exegetical grounds.[122]The doctrine of eternal generation was, historically a central dogma of the church and Christian orthodoxy.[123] This classical doctrine of the Trinity was assumed by the patristic, medieval, and reformed theologians, such as, Athanasius, Augustine, Aquinas, Luther, Calvin, and many others. But it was also the position held by one of the pioneers of the Restoration period, namely, Thomas Campbell, who affirmed the “eternal generation of the Son” and the “procession of the Holy Spirit.”[124] 

The inception of eternal generation originates from Origen and is later refined by the Nicene fathers. Origen suggests that this is “an eternal and everlasting begetting, as brightness is begotten from light.”[125] The Son is eternally begotten from the Father as light is generated from light. “It is through its brightness that the nature of the light itself is known and experienced.”[126] Likewise, the brilliance of God’s glory is revealed through the Son’s reception of divine being from the Father. This doctrine is not a merely philosophical innovation that arose in the early centuries of the church. Instead, it is a way of accounting for the analogy of Scripture as God is not only described as the begotten Son of the Father, but as the “radiance of God’s glory.” This doctrine entails that the Son is eternally begotten from the Father and receives the fullness of divinity from the Father. “It is not, idle curiosity that gives rise to discussion of the Son’s eternal relation to the Father in Christology and the doctrine of the Trinity. Rather,” as Duby argues, “God’s own self-revelation necessitates such discussion, since God’s self-revelation includes that eternal relation within the body of scriptural teaching given to all believers for their growth in the faith…this relation is a relation of origin in which the Son eternally comes forth from the Father and, in so doing, receives from the Father the divine essence.”[127]

The doctrine of eternal generation, according to Jameison and Wittman, is revealed “through a series of images or analogies that characterize the Son as both possessing the divine nature and deriving that nature from the Father. These images or analogies do not give us any kind of exhaustive grasp of the mystery of the intradivine relations. Instead, the light they shed on this reality is oblique and partial but nonetheless reliable and sufficient.”[128] The symbol of light radiating from a source is the analogy that God chooses to employ when revealing His eternal relation with the Son by way of generation. This analogy includes three elements of negation: (1) there is “no beginning” as the light that radiates from its source cannot exist without the other, the Father and Son cannot exist without one another (2) there is “no diminution” since the radiance and light cannot be reduced to something else since they are inseparable just like the Father and Son, and (3) there is “no material derivation,” that is, the eternal generation of the Son is spiritual or incorporeal it is not physical or biological.[129] 

            God reveals Himself analogically by descending to the level of comprehension of those to whom He unveils His glory. “The task of offering description of God in himself,” Duby writes, “necessarily involves using language that human beings customarily apply to themselves and to fellow creatures.”[130] Light acts as the best illustration or metaphor to describe the generation of the eternal Son. The imagery of this analogy describes the Father-Son relationship as the Son not only is begotten from the Father but is seen as light from light when “God naturally radiates his Son.”[131] The Son, as the radiant beam of divine glory, is, as Matthew Barrett writes, “the resplendent ever lucent, and beaming effulgence of God and his everlasting immensity.”[132] As the Son shines the glory of the Father, He is then identified as light. Barrett further notes, “The Son is light because he is the eternal offspring of light.”[133] 

It is the light of the Father’s glory that shines through the Son. As John Owen wrote, “The eternal glory of God, with the essential beaming and brightness of it in the Son, in and by whom the glory of the Father shineth forth unto us.”[134] What the Father generates or communicates to the Son is divine glory, that is, the divine essence or substance. Bavinck suggests when the Son is begotten from the Father, the Father, who “is eternally Father” generates the Son “out of the being of the Father from eternity.”[135] That is, the eternal generation of the Son entails “the Father begets the Son out of the being of the Father.”[136] John Webster highlights the glory of the Son.

“As ἀπαύγασμα, the Son is the self-diffusive presence of the one who is himself unapproachable splendour. God’s glory is God himself in the perfect majesty and beauty of his being. This glory is resplendent. Because God himself is light, he pours forth light. God is glorious and therefore radiant. The enactment and form of this divine radiance is God the Son: he is the particular luminous reality in and as which the glory of God presents itself in its brightness. In this respect, ἀπαύγασμα bears an active sense, the radiating of light from a source. The metaphor thus indicates the unbroken continuity of being between God’s glory and its effulgence; light and its splendour are one. The Son is not a body illuminated by a light outside himself, which light he then reflects; rather, his being and act are the actuality of the divine radiance, not simply its mirror.”[137]

Webster’s treatment of Hebrews 1:3 explores the analogy of light as it is applied to God’s Son. “The metaphor attests a double reality of filiation and of manifestation: of how the Son has his being in relation to the Father, and how the Son radiates the presence of God’s majesty.”[138] By way of analogy, “we see that the radiance from the sun is integral to it and that the substance of the sun is not divided or diminished, but its substance is entire, and its radiance perfect and entire, and the radiance does not diminish the substance of the light but is as it were a genuine offspring from it.”[139] The inseparability of the Father and Son in the eternal relations of origin are then understood analogously by “the procession of light from the sun.”[140] If we were to say the Son began to exist when He was begotten, this would necessarily place God the Father within time and assign to Him a beginning which disregards His eternal relations of origin as the Unoriginate Begetter who generates His Son and breathes out His Spirit from all eternity.[141] There never was a time when the Father was without His Son just like the sun was never without its radiance.

The Father is seen as “the natural principle of the Son.” As Swain states, “as light naturally radiates its brightness, so too God naturally radiates his Son.”[142] It is God the Father who is the “eternal source” and “everlasting principle” of the Son who eternally begets Him.[143] The radiance of light cannot exist without the source of light. But notice how the generation of the Son is eternal. There is no priority of one person over another in chronology or ontology. As Augustine said, “One exists not as before the other, but as from the other.”[144] In the simplest terms, the doctrine of eternal generation relays the “fromness” of the Son. Augustine argued on this basis, “as being born means for the Son being from the Father, so being sent means for the Son being known to be from the Father. And as being the gift of God means for the Holy Spirit proceeding from the Father, so being sent means for the Holy Spirit his being known to proceed from the Father.”[145] Augustine offers us a few things to consider here. First, there is no confusion among the persons when the Son is sent from the Father. This “fromness” is not interchangeable. The Son is from the Father, but the Father is not from the Son. Second, the divine missions point to one who sends and another who is sent. The reason why the Son is sent from the Father and not the Father sent by the Son is not due to any imperfections or inferiority but is a matter of divine relations. The eternal relations of origin are acted out in salvation history where we notice the divine missions, God’s external actions (ad extra), give us a sneak peak at His divine ontology, God’s internal actions (ad intra).

The divine missions introduce the eternal relation of the Triune God by distinguishing the divine persons in the economy. God’s revelation through the incarnate Son introduces us to the blessed Trinity as the Father sends His Son and Spirit.[146] Fred Sanders highlights the divine missions as the self-revelation of the Triune persons in salvation history. In other words, we encounter the Trinity in the events of the incarnation and Pentecost where God reveals the distinction of persons, relations, and roles.[147] The Trinitarian missions reveal the existence and order of the Triune relations but do not unfold these relations of origin exhaustively. However, the Trinity should not be confused and distorted by wrapping up our understanding of the immanent Trinity with the economic Trinity.[148] Sanders rightly notes, “The temporal missions of the Son and the Spirit make known the eternal processions of the Son and the Spirit. The Son is sent to be incarnate because he stands in an eternal relation of origin with regard to the Father, a relation called generation or begetting; and the Spirit is poured out because he stands in an eternal relation of origin with regard to the Father, a relation called spiration or breathing-out.”[149]

“LIGHT FROM LIGHT”: THE BOOK OF HEBREWS’ INFLUENCE ON NICENE TRINITARIANISM

Nicene Trinitarianism offers a rigorous treatment on the essence, relations, and roles of the Triune God as a defense against heretical viewpoints, primarily in regard to the Arian Christology of the fourth-century.[150] In order to combat these theological deviations, the Nicene fathers constructed the Nicene Creed which promoted and protected the eternal generation of the Son. “We believe…in one Lord Jesus Christ, the only Son of God, begotten from the Father before all ages, God from God, Light from Light, true God from true God,  begotten, not made; of the same essence as the Father.” The Son of God is, as Basil of Caesarea proclaimed, “begotten light.”[151] What this entails is that “as the Father is God, who like a light enkindles another light, so the Son is true God from the true Father, the source of divine light.”[152]

Eternal generation was the centerpiece of Nicene orthodoxy. The Nicene Creed primarily focused on the Father-Son relation and aimed against the Arian’s position on the Son’s generation; rather than, more broadly speaking, His divinity.[153] When interpreting Scripture, Nicene Trinitarianism should not be viewed as an imposter but an aid. The Nicene Creed derives its understanding from the Scriptures as it accounts for the familial metaphors and light imagery used to describe the Trinitarian relations. The analogical phrase “light from light” clearly draws from Hebrews 1:3 along with its implications. First, it demonstrates the inseparability of light (source) from light (radiance).[154] Second, it is distinguishable as the light radiates the substance of the light and the source of light causes the brightness to shine.[155] Third, it displays the lights (radiance) origin from light (source).[156] Fourth, it insists the shared substance of light.[157] The “light from light” phraseology is evidence that the eternal generation affirmed by the early church fathers is an attempt to acknowledge the biblical data and employ language that best describes the procession of light from light.

In conclusion, the eternal generation of the Son is a doctrine that needs to be defined, developed, and defended on biblical, historical, and theological grounds.[158] Eternal generation is essential to confess the relations and ontology of the Son in the Trinity.[159] It is not a innovation of the early church but a reflection of the biblical portrayal of the eternal Trinity. “To deny that the Son is eternally generated by the Father,” Kevin Giles writes, “is to undermine the very doctrine of the Trinity, which was developed to safeguard the full divinity of the Son. If the Son is not fully God for all eternity, then our salvation is in jeopardy. Only God can reveal God, only God can save, and only God should be worshiped.”[160]  The reason this teaching was the bulwark of Christian orthodoxy is because it was a central tenant of the apostolic faith that rested upon the divinity of the Son. If we abandon the eternal relations of origin within the Trinity, we forfeit the Trinitarian grammar that allows us to explain and experience Scripture’s portrayal of the radiant divine glory revealed in the Son.

[28] Jamieson, The Paradox of Sonship, 49. The title “Son,” as Jamieson suggests, “not only designates Jesus as divine, it also distinguishes him from the Father and the Spirit, whom Hebrews also identifies as divine persons within the unity of the one God. The chief means by which Hebrews identifies Father, Son, and Spirit as three distinct divine subjects is by assigning to each a role as speaker of Scripture, as Scripture’s promises and foreshadowings find embodied fulfillment in the incarnate economy of the Son. The Father addresses the Son, the Son responds to the Father, and the Spirit calls the believing community to hold fast the saving effects of the Son’s incarnate acts. That ‘Son’ designates a mode of divine existence distinct from that of the Father and Spirit is also implicit in the two essential predicates of 1:3a. Both not only identify the Son as possessor of the divine essence but also suggest that the Son exists from the Father as radiance from light and impress from original. Such conceptualities deposit us on trinitarian territory. While Hebrews does not articulate an explicit, conceptually ordered doctrine of the Trinity, its theological grammar is implicitly trinitarian: Hebrews both identifies the Son as God and distinguishes the Son from the Father and the Spirit.” (74-75)

[33] “The language of Christ’s preexistence permeates the entire letter to the Hebrews. The reality underlying this language is what underpins Jesus’ full and complete humanity, and gives worth to the sacrifice he made. The author emphasizes Christ died for sinful humanity and God vindicated his sacrifice. Neither Christ’s sacrifice nor the christology of Hebrews makes sense apart from belief in Christ’s preexistence…the author of Hebrews begins in the first paragraph to present Christ as the preexistent Son of God and continues to emphasize this aspect of his being throughout the remainder of the letter. Beginning with Christ’s preexistence, the author traces his career through his earthly life, sacrificial death and glorified postexistence in heaven. The same Jesus is the subject of each of these experiences, and the later ones derive their significance from his original condition.” (Douglas McCready, He Came Down from Heaven: The Preexistence of Christ and the Christian Faith [Downers Grove, IL: IVP Academic, 2005], 124)

[39] “Hebrews’ differentiates the relationship between God of Israel and Jesus at the outset of his letter using the language of Son and Father. In the author’s initial assertion, it is implied that God’s speech is that of a Father because God is now speaking in a Son, and it soon becomes clear that this Son is God’s.” (Peeler, “What Does ‘Father’ Mean?,” 66)

[41] “In each category Hebrews portrays Jesus as both truly God and truly human, like his Father in every respect and like humans in every respect. The most fundamental category is that of the Son of God who shares eternally the unique identity of his Father, the unique identity of the God of Israel and the God of all realty. But sonship to God also characterizes Jesus’ human solidarity with his fellow-humans. His mission in incarnation was to bring many human sons and daughters of God to glory (2:10-12). Thus sonship in Hebrews is both a divinely exclusive category (Jesus’ unique relationship with the Father) and a humanly inclusive category (a form of relationship to the Father that Jesus shares with those he redeems). As the eternally pre-existent Son of God, Jesus Christ is destined and qualified for the two main roles in God’s eschatological activity of salvation. because he is the unique Son of the Father, appointed heir of all things (1:2), he can exercise God’s eschatological rule over all things as Lord, and he can make full atonement for sins as the heavenly high priest. But, in both cases, he must also be fully human.” (Bauckham, Jesus and the God of Israel, 236-237)

Eerdmans, 2009), 108. Attridge also rejected a Trinitarian interpretation of Hebrews and concluded, “Hebrews is obviously not interested in working out the details of a Trinitarian theology, but it is also clear that, whatever the precise theological implications, our author has a notion that the Son, agent of divine creation and redemption, shares in the glory, status, and very reality of God.”  In spite of Attridge’s anti-Trinitarian reading of Hebrews, he admits that the identity of the Son can be seen. While Attridge suggests there is no Trinitarian theology in Hebrews, he does note “it holds in tension affirmations that will govern ‘orthodoxy’: the eternal relationship of the Son and Father and, by implication, the divine character of the Son, and, at the same time, the fully human character of the one who is Son.” (109)

[46] Peeler, “What Does ‘Father’ Mean?,” 66.

[47] Cullmann readily admits New Testament’s use of “Son of God” as a Christological title “does point to Christ’s coming from the Father and his deity.” Yet, he was careful not to interpret this title anachronistically by imposing the theological terminology, such as “substance” or “nature” produced in Christological debates. He writes, “We must guard against ascribing also to the first Christians—much less to Jesus himself—the intention of using the Son of God designation to say something about the Sons’ identity of substance with the Father.” (The Christology of the New Testament, 270)

[48] Fred Sanders, The Triune God (Grand Rapids, MI: Zondervan Academic, 2016), 129. “The source or principle from which the Son originates is not a place, btu a person: he is form the Father. His origin from the Father as a personal principle fully fixes his character and adequately accounts for his identity. Paternity displaces provenance so throughly that we no longer ask what location the Son is from: the Father is the all-sufficient whence of his begetting. ‘Begotten from the Father’ refers the Son to his source in a total way.” (“Only Begotten Son: The Doctrinal Functions of Eternal Generation” in On Classical Trinitarianism: Retrieving the Nicene Doctrine of the Triune God. Ed. Matthew Barrett [Downers Grove, IL: IVP Academic, 2024], 422)

[49] “It is precisely by this begetting of the Sonn inn the love of the Holy Spirit that the Father actualizes is identity as Father. The Son subsists eternally as Son only in relation to the Father and to the Holy Spirit, for his very identity is predicated upon his being begotten of the Father in the love of the Holy Spriit who conforms him to be the loving Son of the Father…the Son is begotten by the Father in the love of the Spirit.” (Thomas G.

[57] John Webster notes, “As the act of the Father towards the Son, generation involves both the Father’s active relation to the Son (generatio activa) and the Son’s relation to the Father by whom he is generated (generatio passiva). Generation is thus a constitutive element of the relations between the first two triune persons: paternity and filiation are inseparable from eternal generation…the Father who has life in himself grants the Son also to have life in himself; and the Son gives life to whom he wills” (God Without Measure, I:30-31) Similarly, Thomas Weinandy highlights the dynamics among the persons of the Trinty as “subsistent relations” that reveal four implications. First, these relations among the Triune persons are acquired through “their unique personal identities in relation to one another,” that is, the Father, Son, and Spirit are not different because of their substance but are distinguished by their relations. Second, the relations unpack the “the very act that identifies who each person is” where the Father begets the Son and spirates the Spirit (paternity), the Son is begotten from the Father (generation), and the Spirit proceeds from the Father through the Son (filiation). Third, the relations among the divine persons specify the “singular ontological personal identity,” that is, “what makes them three distinct subjects.” Fourth, the eternal relations of origin explain how the persons possess an “ontological unity as the one God” whereby the one God exists as three distinct persons “ontologically subsisting in relations to one another.” (Weinandy, “The Eternal Son,” 389-390)

[66] “Those who emphasize sameness frequently use language which predicates the same quality univocally of Father and Son—for example, Father is God, Son is God; Father is light, Son is light. These theologians also use terminologies that emphasize the Son derivatively sharing in almost all the Father’s characteristics…the language of the Sons’ ‘generation’ here implies not just a ‘mirroring’ of the Father by the Son—as the reflection of an object shares only the appearance of that object—but a real sharing of nature and qualities.” (Ayres, Nicaea and Its Legacy, 41-42)
