October 8, 451: The Council of Chalcedon opens to deal with the Eutychians, who believed Jesus could not have two natures.

The council condemned the teaching as heresy and created a confession of faith which has since been regarded as the highest word in Christology (see issue 51: Heresy in the Early Church).
