Now they are relatively few in number and have divided into three churches: the Chaldean Catholic Church—an Eastern Catholic church in full communion with Rome—and two Assyrian churches which are not in communion with either Rome or each other. The Chaldean Catholic Church is the largest of the three. The groups of Assyrians who did not reunify with Rome remained and are known as the Assyrian Church of the East, which experienced an internal schism in 1968 which led to the creation of the Ancient Church of the East.
