Catholicism is quite a sufficient religon. In the ancient religions (except for the Egyptian one), no man could become a God. In Ancient Greece, there was Hercules, of course, but he was already half a god. No one born to two humans could be a God. Christianity however, replaced Zeus as uppergod by one almight God while the lesser Gods became saints - in theory, obviously.
But then every human could - and can - become a saint, as long as they 'engaged' in working two miracles, or be a martyr for the church. In other words, you'd have to have your name mentioned in two scientifically unprovable events, or get killed for a reason which is based upon religion. That is all which is needed. The Holy Seat in Rome will gladly use you for their thirty minutes of propaganda
