Not so partner. The early church was centered in Constantinople. All early churches were equals in the first several councils. (held in turkey) Rome eventually demanded all others recognize their primacy. Rome split away to become a defacto secular government, after the fall of the western Roman empire.
And in what Russian city were you raised and in what Orthodox church did you worship? My heritage is Texan by the way,,,
St. Ignatius writes of the primacy or the bishop of Rome in 2c. and the Orthodox Church agreed to the primacy of Rome since then, even though attempts to similarly elevate Constantinople were made. The Orthodox Church was one and the same with the Catholic Church till the Great Schism of 1054, which had nothing to do with the papacy anyway.
I did not seriously practice the faith till my adult conversion to Catholicism, but I was baptized Russian Orthodox in a small church near Moscow, as an infant, one of the happiest days of my life. I recently found that church in Google Earth.
