Really good points maksym. The problem with the Protestant movement it is they have complete ignorance of the East Orthodox Church. In their effort for reformation in the Roman Catholic Church, they ignored fundamental facts of Christianity and instead of looking at the origins of Christianity they proceed with new ideas. Unfortunately the time of reformation there wasn't East Roman Empire, due to the fall of Constantinople at 1543 A.D by the Othoman Turks and the Orthodox Church was now under the Turks.
A basic mistake is to ignore the Biblical Canon consisting 76 Books. How come all protestant groups, including JW's, claim that they follow the Bible, but they ignore 10 books from the Old Testament that they are included in the Canon?
End another important issue. Most of Protestant groups claim that they are only following the Bible, and due to that they are the only ones who are correct in Christian faith. But here comes the big question that they must answer:
Who gave you the Bible? Or from who did you borrowed the Bible? The answer is clear: From the Orthodox/Catholic Church! So how come they claim that the Apostolic Church turned into apostate Church, but THEY ACCEPT THE BIBLICAL CANON defined by apostate Church around 425 A.D a time that according to them, true Christian faith lasted only 200 years??? Does it make sense? You cannot have the Bible alone with out the Church because it was from the Church that Bible was delivered. Besides we have lot of Church Fathers writings from the first three centuries that the Church accepts them and the Bible is not the only Book that defines Christian faith, but the entire Church. Apostle states this very clearly, in his Epistle to Timothy I, chapter 3:15: "..and if I should be delayed, (I am writing to you) so that you may know how to conduct yourself in the house of God, which is the Church of the Living God, the pillar and the basis of the truth."
After the Schisma occurred at 1080AD as I said previously at my post, the West Roman Church fall into serious mistakes, while the East Roman Church, now named Holy Catholic Orthodox Apostolic Church continued to hold the faith and tradition of the Apostles , along with Apostolic Succession going 2000 years back, something that no protestant group has.
So the Apostolic Church is always here for last 2000 years and never sized to exist. In fact the Bible that is used at the Orthodox Churches are the Original Greek Texts, because translations can lead into interpretation mistakes (like Catholics and Protestants) and to avoid that they are using the Original Texts that the meaning is clear.
P.S. Peter was in Rome. For Early Christians the code name for Rome was Babylon due to the pagan
God's that Romans used to worship.
