Physicalism and the Incarnation

Trenton Merricks holds to a physicalist view of the Incarnation according to which the Son transformed into a physical object (the body of Jesus) at the Incarnation. R. T. Mullins, in “Physicalist Christology and the Two Sons Worry,” claims that Merricks’s account is Nestorian since it entails that it is metaphysically possible for the human nature of Christ to be a person independently of the Son’s incarnation. While I am not a physicalist, in this essay I defend Merricks’s view against Mullins’s claim. I argue that if the Son is numerically identical to the body of Jesus, then it is not possible for the body of Jesus to exist independently of the Son’s incarnation.
