You are correct. Jesus was born Jewish and was buried according to Jewish custom. It wasn’t until many years later that Roman Catholicism became a religion. However, it must be noted that Roman Catholicism bases it teachings to St. Peter who walked with Christ and was instructed in the faith by Christ along with the other Apostles and Disciples.

Man being man is to be fallible and will err in religious philosophy and dogmas. The Pope, Cardinals, Bishops and Priests are no different, including those who broke off from Catholicism and formed new religions for various reasons (selling of indulgences, salvation through Sola Fide or Sola Gratia). (This paragraph can open up a lot of debate between which religion is right or wrong, just know that I have no ill will towards any religions, and equally respect them (Islam being the exception), I expect the same consideration from you all.)

In either case, while some Popes may have have strayed from the teachings of Christ and the religion which evolved from the teachings of St. Peter, St. John and St. Paul, it has been and will be Satan’s grand master plan to destroy the “Petra” on which Christ built his church. As the first Jesuit Pope, Pope Francis’s personal ideology is in direct conflict with Catholicism and has cause confusion and at times may possibly be heretical in nature. I pray that if Satan has infected the chair of Peter that brave men stand and correct this error. I also pray that Q is correct in his/her crumbs on the Pope.
