In this paper I present and defend two arguments which purport to show that the doctrines of timelessness and the Incarnation are incompatible. An argument similar to the first argument I consider is briefly discussed by Stump and Kretzmann in their paper "Eternity." I argue that their treatment of this type of objection is inadequate. The second argument I present is, as far as I know, original; it depends on a certain subtlety in the doctrine of the Incarnation, viz., that (...) the Son took on or assumed a human nature. It seems that there is no way to understand what it is for the Son to take on a human nature that doesn’t entail his mutability; and mutability entails temporality. Thus, since Christ is said to take on a human nature, an orthodox Christology must maintain that the Son is temporal. I conclude by considering whether the Son’s temporality entails the temporality of the Godhead. (shrink)
