Nope, itâs an argument about the identity of the Church of Christ. The Orthodox claim the Church is the Orthodox Catholic Church, and we Catholics claim the Church is th Catholic Church. I have shown, using the Church Fathers, by Godâs grace, that the proper name or identity of the Church is Catholic Church. Some Orthodox are attempting to show me Iâm wrong by pointing out the fact that the Orthodox Church has a similar name to the Catholic Church and that the Church Fathersâ writings all defend the Orthodox, and so I am giving them the chance to defend their belief about the Orthodox Church by showing me one Father who speaks of the Church as the âOrthodox Catholic Churchâ, that is, this being its proper name.
