What separates the Roman Catholic Church and the Eastern Orthodox Church is not only the Primacy of the Pope also known as the Infallibility, but also the following innovations of the Roman Catholic Church: The Procession of the Holy Spirit. Purgatory and indulgences. The Immaculate Conception of the Virgin Mary. Assumption of the Virgin Mary. Invocation of the epiclesis. Unleavened Bread. Holy Communion. Divorce. Clergy's Martal Status. The Orthodox claim in being the 1st Church is historically (untrue) because they refuse to accept the Primacy of the Pope. Since the 1st Pope was Peter, the Catholic Church was the only Church that recognized his primacy. and the Orthodox Church was merely a branch of the Catholic Church from the very beginning of the Church!<quoted text>
***What say yu about the other Catholic Church...The Ortherdox branch of the Catholic Church?
