True the sins of disunity is to be found on both sides. Just was posting what I was taught in regards to the history of the Christian faith.
For the record, I agree the Primacy of the Church of Rome is something that was willed by God and is important for the Unity and mission of the Universal Church. So Doctrinally speaking, I think spliting with Rome was not a good thing for the Orthodox to do. However, not having the fullness of the Eastern Tradition hurt the Church in the 2nd millenium as well.
Still, wounds to disunity are always the consequence of sin by human beings, and of that, both Catholic and Orthodox clergy and political leaders share in it. That was the point I clumsily made.
Thanks
