Misunderstandings of each others expression of faith that is interpreted from Latin and Greek languages and writings. At least that is St.Augustine’s argument, during his era. History repeats this era once again, in our time.
Today, from my dialogue experience with the many Orthodox Church’s comes from a misinformed and an anti-Latin Catholic sentiment, that almost always (after the misinformation is cleared up) deals with the authority of Peter’s Chair or the Bishop’s of Rome.
The Orthodox Church’s today, remain in some way or form attached to their secular powers. For example; The Russian Orthodox Church was severely suppressed by Communism. Thank God, for St. Pope John Paul II, who proclaimed in the midst of the Communist powers,“it is Ok to believe in God”, then the walls came tumbling down. The Orthodox Russian Church is freed and supported by the present secular Russian powers in Putin himself.
History records the Ottoman Empire did all they could from ever allowing the Orthodox Church’s from ever uniting with the Bishop of Rome and keeping their Bishop’s from ever attending Church councils with the West.
So long as the Orthodox Church’s remain influenced by secular powers. When these secular powers are anti-Western religious and anti- Western secular powers. We will continue to experience these secular powers feeding the schism and supporting the anti-Bishop of Rome rhetoric, hence the hidden propaganda influenced by secular powers impact’s our ecumenical efforts in a negative way. When a secular power is financing the building of your church’s and financing your living, it is hard to leave the hand that feeds you. I am speaking to the leadership here, and not the pious Orthodox members.
