Why would the Bishop of Rome be your enemy?
Orthodox Christians have more to detest about Rome than anyone. But...Apostolic Succession is REAL.
I would not want to face the Lord with malice toward one of his chosen Bishops........
So I take it you have low regard for St. Athanasius? "The floor of hell is paved with the skulls of bishops".
Let's think of some of the Reformation era Popes that you hold in esteem.
Sixtus IV - Nepotism (a half dozen nephews appointed as Cardinals). Conspiracy to commit murder.
Innocent VIII - at least one marriage, one legitimate and a number of illegitimate children. Only appointed one nephew a Cardinal.
Alexander VI - several mistresses (one only 14 years old). Several illegitimate children by several different women, including married women.
Need I go on?
