Who really separated from the other Catholic or Orthodox?

Answer 1

Catholic AnswerThe Catholic Church has an unbroken lineage stretching back to the first Pope, St. Peter, who died in Rome. His body is interred under the high altar in St. Peter's Basilica, you may view it today by going to Rome, and going down the stairs. There has been a continuous line of Popes who have occupied his "Chair" in Rome since then. The Orthodox argued with the papacy and broke from it in the eleventh century. The way that you can tell that they broke with Rome is that each Orthodox Church is from a separate Rite of the Catholic Church. In the eleventh century, when they split, half formed the Orthodox and half of each Rite remained with Rome. Thus today you have a Greek Orthodox Church AND a Greek Uniate Rite. Each Orthodox Church has a corresponding Rite within the Catholic Church which has always been there. The Orthodox left the Catholic Church, but they are currently in discussions with Rome, and there is ever hope that the Rites may be reunited in the future, please keep them in your prayers.
