What happened when God took flesh? A simple question roused hundreds of speculative answers, most concerning the “person” and “nature” (or natures) of Jesus Christ. But the philosophical terms themselves were slippery, and mistranslations only made matters worse. The wild speculation came to a stop at the Council of Chalcedon, thanks to a letter from Pope Leo the Great. His “Tome” defined terms with abundant clarity. Since then, in mainstream Christianity, Orthodox Christology has been Chalcedonian Christology. The Tome is a necessary point of reference for all subsequent doctrine of Jesus Christ.
