I am presently reading "A short history of Byzantium" by John Julius Norwich, and it strikes me when reading it that even after AD 400 there still were examples of people in high positions that belonged to varieties of Christianity considered as heretic by the authorities. The same even applies with Pagans. A Greek, Pagan woman, named Athenais, even got access to the court and later married Theodosius, although she had to convert before the marriage. With the death of the Emperor Marcian in 457, the chief of the army, named Aspar, was suggested as new emperor. He was not picked as he was an Arian, still the fact that he had managed to become chief of the army shows that Arianism was not totally suppressed. The same applies even with Paganism, as it did not stop Athenais from getting access to the court. I thought that "heretic" Christianity and Paganism became illegal in 392, when Theodosius declared Orthodox Christianity as the only religion in the country?
