Christadelphians deny the traditional reading of John 1:1 as asserting the pre-existence of a divine Logos or a second person of the Godhead. Instead, Christadelphian theology interprets the Logos as God's wisdom, reason, and plan rather than as a pre-existent person. The Word (Logos) came into existence at the incarnation; Jesus of Nazareth is the 'Word made flesh,' but not a pre-existent divine being. This interpretation is fundamental to Christadelphian non-Trinitarianism.

Christadelphian exegesis argues that John 1:1 cannot mean Jesus was God in the divine sense, as this would contradict the principle of God's absolute oneness and Jesus' own statements of dependence on the Father. Instead, Jesus is understood as the Son of God—exalted and divine in function, but not God in essence. The incarnation is the beginning of the Word, not the appearance of a pre-existent divine person.
