Jesus was a Jew and the first convert to the Catholic Church; the Church Christ built. The "denominations" and other cults sprang forth 1500+ years later.
Beware of false prophets.
Jesus founded the catholic church, not the Roman Catholic church, that did not exist until Constantine. He is the father of the Roman church, not Christ.
He took a church that had a biblical basis and added to it all manner of pagan practices that Catholics today call "tradition"
What?!
