I recently explored the Cosmological Argument of St. John of Damascus (or what I would now call the “Damascene Ontological Argument”) and have realized something in the argument that needs clarification, namely, how could God remain unchanged in light of the Incarnation? (Much thanks to my friend Vic and commenter CK for bringing this problem up)
My first proposition looks like this:
(1) All things are either created or uncreated
(1a) If they are created then they are changeable
(1b) If they are uncreated then they are unchangeable
For God to be eternal, this means that He must be unchangeable, but how can this be so in light of the Incarnation? Wouldn’t this indicate “change”?
St. John sheds light on what he means by “change” when he argues that an angel or human can “change” by doing something moral or immoral. A human can have another human, thus increasing the quantity of humans, indicating a change. A human also changes physically. Thus, humans change. Christ, who is God, was also a human. The question then becomes, how could Christ be both man and God, but not change? If Christ didn’t change, then He isn’t human. If He did change, then He isn’t God.
