The Christian Orthodox Church goes back to the Apostles. For the first 1000 years after Christ, there was one Christian Church. Then, in 1054, there was the Great Schism and Rome (not the empire, but the Church of Rome and those churches under its Bishop’s authority) left changing existing doctrine and making new doctrine.
But the rest of the original Church adhered to the original doctrine and the original Seven Councils. There was no reformation for the Orthodox Church because the faith was not changed. For doctrine to be established in the Orthodox Church, the whole Church would have to agree, not just one man i. e. the Pope. As a result, the Orthodox Church has held true to the teachings and traditions of the Apostles and the Church Fathers.
We are here and ready to welcome you and help you with your journey back to the original Christian Church.
I believe in one God the Father almighty, Maker of heaven and earth,
and of all things visible and invisible.
And in one Lord Jesus Christ, the Son of God, the only begotten, begotten of the Father before all ages, Light of Light, true God of true God, begotten, not made, of one essence with the Father, by whom all things were made. Who for us men and for our salvation came down from heaven, was incarnate of the Holy Spirit and the Virgin Mary, and was made man; and He was crucified for us under Pontius Pilate, and suffered and was buried; and the third day He rose again according to the Scriptures; and ascended into heaven and sits at the right hand of the Father. And He shall come again with glory to judge the living and the dead; Whose kingdom shall have no end.
And in the Holy Spirit, the Lord, the Giver of life, Who proceeds from the Father, Who with the Father and the Son together is worshipped and glorified; Who spoke by the prophets. In One Holy Catholic and Apostolic Church. I acknowledge one baptism for the remission of sins. I look for the resurrection of the dead, and the Life of the world to come.
