Adoptionism, also called dynamic monarchianism, is a belief concerning Christ that first appeared in the second century. Those who held it denied the preexistence of Christ and, therefore, His deity. Adoptionists taught that Jesus was tested by God and after passing this test and upon His baptism, He was granted supernatural powers by God and adopted as the Son. As a reward for His great accomplishments and perfect character Jesus was raised from the dead and adopted into the Godhead.
