Abstract
According to Christian belief, Jesus Christ is a divine person who became “incarnate,” i.e., who became human. A key event in the second act of the drama of creation and redemption, the incarnation could not have failed to interest Aquinas, and he discusses it in a number of places. A proper understanding of what he thought about it is thus part of any complete understanding of his work. It is, furthermore, a window into his ideas on a variety of other topics: God, human nature, language, substance, and so on. Finally, it forces us to come to grips with what is at stake
in acknowledging that Aquinas was not only a philosopher but a theologian as well.
