Abstract
The Incarnation is the doctrine that the second person of the Trinity (SPT) became fully human while remaining fully divine. An orthodox model of the Incarnation must maintain the omnipotence and omniscience of SPT throughout the period of humiliation. Concretists tend to think of the Incarnation in mereological terms, claiming that SPT came to stand in a mereological relation to a particular human being. As an animalist, Trenton Merricks claims that at the point of Incarnation, SPT became an animal, a composite material object. To adapt a frequent comment of Plantinga's, “Materialism is all the rage these days”. This is true even among Christian theologians and philosophers more elaborate versions and defenses of materialist Christology in the future. Nevertheless, these projects are misguided. The Incarnation, the central doctrine of the Christian faith, is a very poor fit with materialism. It fits quite well with Cartesian dualism, however, so Christians should be dualists.
