Religion may be the most enduring and fascinating aspect of the Byzantine Civilization.
Emperor Constantine had adopted Christianity as his faith and he died the first Christian emperor of the Roman Empire. After Constantine became a Christian, and saw it become accepted as a religion, and after it subsequently became the only tolerated religion, the empire slightly modified its old pagan tradition of worshipping the god-emperor. The emperor was no longer a deity; however, it was believed that he was ordained of God to rule, and his power was divine.
