It is often argued by the Eastern Orthodox that rather than there being a Papacy in the early Church, there was a Pentarchy, consisting of the co-equal leadership of the Church by the Five Patriarchates: Rome, Constantinople, Alexandria, Antioch, and Jerusalem. From this the Eastern Orthodox argue that Rome "fell away" from the orthodoxy of other Four Patriarchs, demonstrating that Rome is the odd-man-out and clearly in the wrong. Obviously only one of these can be correct, as they are two mutually exclusive forms of ecclesiology. The focus of this post will show that the Eastern Orthodox concept is false, and from this refute the idea that Rome is effectively 'out voted' 4-to-1 by the other Patriarchs. I will be presenting two definitive blows to Eastern Orthodox ecclesiology in this matter.
