Theophanes (575 circ.) Chronographia, p. 34, Ed. Paris, 1655, defends the orthodoxy of Cyril, as follows:  “It was right to avoid the word ὁμοούσιος, which at that time offended most persons, and through the objections of the adversaries deterred those who were to be baptized, and to explain clearly the co-essential doctrine by words of equivalent meaning:  which also the blessed Cyril has done, by expounding the Creed of Nicæa word for word, and proclaiming Him Very God of Very God.”
