That may be your supertition but I don't see anything in the scripture where heresies such as Protestantism were tolerated. Either one of the multiple Protestant denominations is the True Church, or the Catholic Church is, together with the apostolic Churches that believe what we do. You cannot have the body of Christ without agreement between the members on the fundamentals of faith, adnd we don't have such agreement with the Protestants.
So you say even if someone has accepted Christ as their personal savior but doesn’t belong to the Catholic church organizationally is not part of Christ’s body the church?
Well then it's time you listen up and pay attention to the truth instead of trying so hard to convince yourself and others that all authority rests with the Vatican instead of in Christ and his rightful authority and the words He left us to live by. That's where we stand..and it's solid ground.
