It is the sad fact of our schism, but the Apostolic Church was Rome and the East together and we have lost that. The united Orthodox Catholic Church.
"It is the sad fact of our schism, but the Apostolic Church was Rome and the East together and we have lost that. The united Orthodox Catholic Church."
Indeed it is a sad fact, a mistake we share and have all paid for. I particularly enjoy reading some of the writings of the Desert Fathers from, say, the 7th century. Throughout the Middle East in those days there were various heretical sects, the largest and best organized of which were called the Severians, named after a deposed Patriarch of Antioch called Severus. They were, at base, Monophysites on steroids. Anyway, when the monks encounter devotees of that sect, they always pray that the person will leave "the heresy of Severus and his false eucharist" and return to the "catholic church", no caps or simply "the church", again no caps. We read the same usage in the original Greek of the Nicene Creed and in the writings of +Ignatius of Antioch.
It is a terrible distortion of history we see when Protestants rail against the "Roman Catholic Church" in the same breath as Constantine, the Council of Nicea etc. Their blind hatred of the Church of Rome gets transfered to the whole Church and so they immediately dismiss the entire patristic era and beyond that 1200 years of Church history. They are less for it.
