There is one Holy Christian Church and that is the Catholic Church.
As for the apostles i only recognize the twelve.
There is a major distinction in REAL CATHOLICS, and fallen away “Catholics” who attend Church once a year at Christmas, and never go to reconciliation. They do not follow the teachings of the faith and shouldn’t call themselves Catholic, because if you don’t abide by the teachings of the Catholic Church, you are no longer a Catholic. The Catholic Church has been putting up with disbelievers for the last 2,000 years. It’s not easy being Catholic. It’s not for wimps.
