No, instead of heresy we can affirm with Chalcedonian Christology that God the Son took on full human existence while remaining what he was as God. In other words, the Word lived as a true man on our scale of limited powers, and he also bore the expression of the Spirit’s presence and action in a human life, in response to the Father. Any work God does in creation is the Spirit’s action, joined with the Word, and from the Father.
