And the popes who misbehaved were excommunicated. Could you imagine a pope being excommunicated today?
Many attempted to… None successfully did because such a thing is impossible.
Secondly many people questioned the Holy Trinity , divinity of Christ and various other teachings. Can you imagine someone in the church doing that today? Nope why? Because we are passed that stage ans now many things implicit are now explicit.
only reason for us to accept them as superlatives in regards to other patriarchs and emperors and as literal facts in regards to the pope is because we are told now that we should. Again, you have to show a pattern of behavior showing the Church believed that way. That’s where the Catholic argument collapses.
Patriarch St. Menas of Constantinople (August 25) says in 536 [Sentence Against ex-Patriarch Anthimus of Constantinople at Local Council of Constantinople in Mansi VIII:967A,970B]:
Indeed Agapetus of holy memory, Pope of Old Rome, giving him time for repentance until he should receive whatever the holy fathers defined, did not allow him to be called either a priest or a Catholic…
We follow and obey the Apostolic Throne; we are in communion with those with whom it is in communion, and we condemn those whom it condemns."
Abbot St. Theodore of Studion (November 11) says in 816 [Letter II:129 to Sakellarios Leo in PG 99:1420A]:
“let him [Patriarch St. Nicephorus of Constantinople] assemble a synod of those with whom he has been at variance, if it is impossible that representatives of the other Patriarchs should be present, a thing which might certainly be if the Emperor should wish the** Western Patriarch [the Roman Pope] to be present, to whom is given authority over an ecumenical synod;** but let him make peace and union by sending his synodical letters to the prelate of the First See.”
Metropolitan Sergius of Cyprus says in 649, in a letter read in Session 2 of the Council of the Lateran [Letter to Pope Theodore I of Rome in Mansi X:914]:
** “O Holy Head, Christ our God hath destined thy Apostolic See to be an immovable foundation and a pillar of the Faith. For thou art, as the Divine Word truly saith, Peter, and on thee as a foundation-stone have the pillars of the Church been fixed.”**
St. Maximus the Confessor of Constantinople (August 13) says [Excerpt from Letter to Peter in PG 91:144BC]:
“Therefore if a man does not want to be, or to be called, a heretic, let him not strive to please this or that man …
but let him hasten before all things to be in communion with the Roman See. If he be in communion with it, he should be acknowledged by all and everywhere as faithful and orthodox.** He speaks in vain who tries to persuade me of the orthodoxy of those who, like himself, refuse obedience to his Holiness the Pope of the most holy Church of Rome: that is to the Apostolic See.**.”"
This is the testimony from the eastern fathers
