Eternal Sonship — Was Jesus Always the Son?
Eternal Sonship is the teaching that the Son did not become the Son at his birth (or his baptism, or his resurrection) — the Father–Son relationship is eternal, "begotten, not made" (Nicene Creed). This is the historic, majority Christian position. A minority of orthodox evangelicals have held "incarnational Sonship" instead (John MacArthur held it for years before publicly changing his view); that view is a mistake, in our judgment, but not a heresy like adoptionism. Here is the case, and how the fathers made it.
The Biblical Case
A relationship that pre-dates creation
John 16:28: "I came from the Father and have come into the world; now I am leaving the world and going to the Father." If the Son "came from" the Father, the Father was already Father before the Son came; the relationship pre-existed the incarnation.
John 17:5, 24: "the glory I had with you before the world existed"; "you loved me before the foundation of the world." A relationship of love, in progress before creation, requires two persons in that relationship before creation — a Father and a Son.
Colossians 1:13; Galatians 4:4. God "sent forth his Son" — you send someone who already exists; the Son is "his beloved Son" whose kingdom believers are transferred into. The Son is spoken of as the Son before the sending.

"Eternal generation" — where it is actually grounded
The doctrine is that the Son is eternally "of" the Father — receiving the one divine nature from the Father — without ever beginning to exist. Its main biblical supports:
— John 5:26 — "as the Father has life in himself, so he has granted the Son also to have life in himself." The Son's self-existent life is from the Father, eternally — this "granting" is the classic proof-text for eternal generation, not a moment in time.
— John 1:14, 18; 3:16 — monogenēs, "only Son / one of a kind," and "the only-begotten God… at the Father's side" (best manuscripts of 1:18).
— Hebrews 1:3 — "the radiance of God's glory": a ray is never later than its light source.
A correction to a common argument. Hebrews 1:5 ("You are my Son, today I have begotten you") is often cited here — but that quotation of Psalm 2:7 is applied in the New Testament to the resurrection and enthronement of the Son (Acts 13:33; Hebrews 5:5; Romans 1:4), not to a timeless "today." It is better to rest eternal generation on John 5:26 and monogenēs, and let Hebrews 1:5 say what Acts 13:33 says it says.

How the Church Read It
Origen, Athanasius, the Cappadocians
Origen, On First Principles 1.2.2–4 and Commentary on Romans: the Son's begetting is eternal and continuous — "there is no when when he was not," and the Father "does not beget the Son and then release him from his begetting, but is always begetting him," as brightness is always coming from light.
Athanasius, Against the Arians 1.14, 1.20–22: "as the Father is eternal, so is his Word eternal"; the Son is "the radiance of the light, and… as long as the light exists, so long is its radiance." To say "there was once when the Son was not" (the Arian slogan) is to say there was once when God was without his Word and Wisdom — impossible.
Gregory of Nazianzus, Third Theological Oration (Oration 29.3): "When did these come into being? They are above time. But if I am to speak with more daring — when the Father did. And when was that? There was no 'when.' … The Father is Father without beginning; the Son is Son without beginning."
The Nicene Creed (325 / 381) fixed the language: "begotten of the Father before all ages… begotten, not made, of one substance with the Father" — and the original creed's anathema condemned anyone who said "there was when he was not."

💡 Eternal Sonship — Reasonable Summary"The Son did not become the Son at Bethlehem: John 16:28 ('I came from the Father'), John 17:5 and 24 ('the glory I had… you loved me before the foundation of the world'), and Galatians 4:4 ('God sent forth his Son') all speak of a Father–Son relationship that pre-dates creation. 'Eternal generation' — the Son eternally of the Father, without beginning — rests best on John 5:26 ('as the Father has life in himself, so he granted the Son…') and monogenēs; Hebrews 1:5's 'today I have begotten you' is applied in the NT to the resurrection (Acts 13:33), so it is not the peg to use. Origen ('no when when he was not'), Athanasius ('as long as the light exists, so long is its radiance') and Gregory of Nazianzus all taught it, and Nicaea made it creed: 'begotten, not made.' The minority 'incarnational Sonship' view held by some evangelicals is, in our view, a mistake — but not the ancient heresy of adoptionism, which denied the pre-existence itself."
