In its most crucial theological usage, "begotten" describes the eternal relationship between God the Father and God the Son — a relationship of origin and essence, not of time or creation. The Nicene Creed confesses Christ as "eternally begotten of the Father, God from God, Light from Light… not made." This is not biological birth; it is the eternal generation of the Son from the Father's very being. Jesus is the "only begotten Son" (monogenes) of God (John 3:16) — unique, one-of-a-kind, fully divine. To be begotten is to share the nature of the one who begets. The Son is begotten, not made; therefore He is God, not creature.
BEGOTTEN, pp. of beget. Generated; procreated. "Only begotten Son" — a phrase peculiar to the Gospel of John, expressing the unique and singular relationship of the Son to the Father.
The Jehovah's Witnesses and Arians ancient and modern have seized on "begotten" to argue that Christ is the first creation of God — a made being, not eternal God. This fundamentally misunderstands monogenes: "begotten" in its Johannine usage does not refer to temporal origin but to unique ontological status. The Nicene Fathers fought precisely this battle in the 4th century: the Son is homoousios (same substance) with the Father, not a lesser being. "Begotten, not made" is one of Christianity's most important clarifications.

• "The Son is eternally begotten of the Father — not created at a point in time, but co-eternal and co-equal with Him."
• "When John says Jesus is the 'only begotten Son,' he means there is no other like Him — He is uniquely and fully God."
• "'Begotten, not made' is the Nicene boundary marker that separates Christianity from every form of Arianism."
