The Holy One in Our Midst: An Essay on the Flesh of Christaims to defend the doctrine of the extra Calvinisticumthe doctrine that maintains the Son of God was not restricted to the flesh of Christ during the incarnationby arguing that it is logically coherent, biblically warranted, catholically orthodox, and theologically useful. It shows that none of the standard objections are devastating to the extra, that the doctrine is rooted in the claims of Christian Scripture and not merely a remnant of perfect being philosophical theology, and that the doctrine plays an important role in contemporary theological discussion. In this way, James Gordon revives an important Catholic doctrine that has fallen out of favor in contemporary theology. Also, this project aims to integrate biblical, philosophical, and systematic theology by showing that the tools and methods of each distinct discipline can contribute to the goals and aims of the others.
