Hopefully you will stay in the one holy catholic church.
The Apostles Creed (portion):
I believe in the Holy Ghost, The Holy Catholic Church, the communion of saints The forgiveness of sins, The resurrection of the body, and life everlasting.
The first thing any Catholic must do to join another Religion is to lose his Faith.
After that it’s easy.
It’s catholic, as in universal, not Catholic, as in a denomination.
My understanding is that the word “catholic” in the Apostle’s Creed is rarely capitalized in English-speaking churches today and that it means of, relating to, or forming the church universal, the ancient undivided Christian church, or a church claiming historical continuity from the ancient Christian church. It is not intended to refer specifically to the Roman Catholic Church.
Catholic is a word which simply means “universal” and is NOT irrovocably tied to the Church organization tied to the Roman Bishop.
All believing Christians are a part of Christ’s catholic Church regardless of denomination. Hence we say the creeds in good conscience, as they nowhere refer to fealty to the Bishop of Rome.
This is why the Orthodox Presbyterian Church does NOT require any sort of re-baptism, if one has already received a trinitarian baptism in another Christian denomination. Christ Church is universal, otherwise there could be no Christians outside of one denomination.
The minute a Roman Catholic concedes that there are genuine Christians out of communion with the Roman Church, logically he must concede the Church is catholic by definition, not a title... that is universal, transcending denominations.
