Well, you're in luck today ol' buddy.

It's rooted in standard Roman Catholic dogma called the apostolic succession, a claim that all duly constituted bishops have had the Spirit instilled in them by men authorized to do so by performing the proper rituals, all the way back to Jesus' disciples. The Pope, as Bishop of Rome, traces his succession directly back to the church's founders, Paul and most particularly Peter, the first Bishop of Rome and the nominal rock on which the church is built, so he gets to be first among equals in the crowd of bishops.
