Eutychianism

Eutyches' view of the nature of Christ

Eutychianism was a Monophysite Christology developed by Eutyches of Constantinople, who was rejected as a heretic at the Council of Chalcedon. It posits that Jesus Christ had two natures prior to the incarnation, and over the course of Jesus' life and ministry, these two became one, culminating at the resurrection.

This view was rejected for denying the unchangingness of Christ.
