His fidelity in refusing this simoniacal betrayal of his trust brought on him the enmity of the most powerful man in the empire. A graver trouble soon arose. In 448 Flavian had to condemn the rising heresy of the monk Eutyches, who obstinately denied that Our Lord was in two perfect natures after His Incarnation. Eutyches drew to his cause all the bad elements which so early gathered about the Byzantine court. His intrigues were long baffled by the vigilance of Flavian; but at last he obtained from the emperor the assembly of a council at Ephesus, in August 449, presided over by his friend Dioscorus, Patriarch of Alexandria. Into this "robber council," as it is called, Eutyches entered, surrounded by soldiers. The Roman legates could not even read the Pope's letters; and at the first sign of resistance to the condemnation of Flavian, fresh troops entered with drawn swords, and, in spite of the protests of the legates, terrified most of the bishops into acquiescence.
The fury of Dioscorus reached its height when Flavian appealed to the Holy See. Then it was that he so forgot his apostolic office as to lay violent hands on his adversary. St. Flavian was set upon by Dioscorus and others, thrown down, beaten, kicked, and finally carried into banishment. Let us contrast their ends. Flavian clung to the teaching of the Roman Pontiff, and sealed his faith with his blood. Dioscorus excommunicated the Vicar of Christ, and died obstinate and impenitent in the heresy of Eutyches.
Feast Day of Saint Flavian
The Feast Day of Saint Flavian is February 17. The origin of Feast Days: most saints have specially designated feast days and are associated with a specific day of the year and these are referred to as the saint's feast day. The feast days first arose from the very early Christian custom of the annual commemoration of martyrs on the dates of their deaths at the same time celebrating their birth into heaven.
