Adoptionism and Christology
Adoptionism is one of two main forms of monarchianism (the other is modalism, which regards "Father" and "Son" as two historical or soteriological roles of a single divine Person). Adoptionism (also known as dynamic monarchianism) denies the eternal pre-existence of Christ, and although it explicitly affirms his deity subsequent to events in his life, many classical trinitarians claim that the doctrine implicitly denies it by denying the constant hypostatic union of the eternal Logos to the human nature of Jesus. Under Adoptionism Jesus is currently divine and has been since his adoption, although he is not equal to the Father, per "my Father is greater than I" (John&verse=14:28&src=! John 14:28). and as such is a kind of subordinationism.
Adoptionism was one position in a long series of Christian disagreements about the precise nature of Christ (see Christology) in the developing dogma of the Trinity, an attempt to explain the relationship between Jesus of Nazareth, both as man and God, and God the Father while confidently claiming to be uncompromisingly monotheistic. It differs significantly from the doctrine of the Trinity that was later affirmed by the ecumenical councils.
