📖 Biblical Definition
Eternal generation is the orthodox doctrine that the Son of God is eternally begotten from the Father -- that the Father-Son relationship within the Trinity is not a temporal event but an eternal reality. The Son does not come into being; He is perpetually generated from the Father's own being, sharing the identical divine essence. Scripture calls Christ "the only begotten Son" (John 3:16, monogenes), the one who is "in the bosom of the Father" (John 1:18). The Father declares, "You are my Son; today I have begotten you" (Psalm 2:7) -- where "today" refers not to a moment in time but to the eternal "now" of God's being. The Son is the "radiance of the glory of God and the exact imprint of his nature" (Hebrews 1:3). As light perpetually radiates from the sun, so the Son is perpetually begotten from the Father -- without beginning, without diminishment, without separation.
📜 Webster 1828 Definition
Webster 1828 does not contain a combined entry for "eternal generation."

Under GENERATION, Webster includes: "The act of begetting; production; formation." Under ETERNAL: "Without beginning or end of existence." The combined theological concept was well understood in Reformed orthodoxy but was treated as a doctrinal matter rather than a lexical one.

⚠️ Modern Corruption
Eternal generation has been denied by some evangelicals and distorted by heretical movements.
expand to see more
Some modern evangelicals have abandoned the doctrine of eternal generation, dismissing it as speculative philosophy. This is historically ignorant and theologically dangerous. The doctrine was not invented by the councils but drawn from Scripture and defended against Arianism (which denied the Son's full deity) and Sabellianism (which denied the distinction of persons). Without eternal generation, the Father-Son relationship becomes either a temporal metaphor or a subordination of being -- both of which collapse into heresy. The Jehovah's Witnesses exploit the language of "begotten" to argue that the Son was created. The Mormons use "firstborn" to argue the Son is a creature. Eternal generation answers both: the Son is begotten, not made; firstborn in rank, not in origin; eternally from the Father, yet co-equal and co-eternal.
Usage
• "Eternal generation means the Son has always been the Son -- there was never a time when the Father was without His Word."
• "To deny eternal generation is to make the Trinity a voluntary arrangement rather than an eternal reality of God's own being."
