The Formula of St. Hormisdas (517) is a Head-On Collision Waiting to Happen for Those Who Want to Avoid the "Question of Rome." Read the Formula that the Emperor Justinian Forced His Eastern Bishops to Sign.
From The Church Teaches, (Rockford, Illinois: TAN, 1973), pp. 69-71.
"During the pontificate of Pope St. Hormidas (514-523), the accession of Justinian [as Byzantine Empire], a Catholic and a Latin, to the imperial throne at Constantinople, provided an opportunity to heal the 35 year old Acacian schism. The document which Justinian ordered the Eastern bishops to sign is a profession of faith, which had been added to a letter that the pope had sent to the bishops of Spain in the year 517. Its acceptance by later councils gives it the value of a definition.
'The first condition of salvation is to keep the norm of the true faith, and in no way to deviate from the established doctrine of the Fathers. For it is impossible that the words of our Lord Jesus Christ who said, "Thou art Peter, and upon this rock I will build my Church? (Matt. 16:18), should not be verified. And their truth has been proved by the course of history, for in the Apostolic See the Catholic religion has always been kept unsullied. From this hope and faith we by no means desire to be separated and following the doctrine of the Fathers, we declare anathema all heresies....Following, as we have said before, the Apostolic See in all things and proclaiming all its decisions, we endorse and approve all the letters which Pope St. Leo wrote concerning the Christian religion. And so I hope I may deserve to be associated with you in the one communion which the Apostolic See proclaims, in which the whole, true, and perfect security of the Christian religion resides. I promise that from now on those who are separated from the communion of the Catholic Church, that is, who are not in argreement with the Apostolic See, will not have their names read during the sacred mysteries.
But if I attempt even the least deviation from my profession, I admit that, according to my own declarations, I am an accomplice to those whom I have condemned. I have signed this my profession with my own hand and have directed it to you. Hormisdas, the holy and venerable pope of Rome."
