In-game Catholicism refers to forms of Christianity post-schism that was followed by most, if not all of Western Europe up until the Protestant Reformation. Catholicism refers to the hierarchy and practices of the Roman Catholic Church. Catholicism was formed from Chalcedonism after the Great Schism, which resulted in Catholicism in the West, and Orthodoxy in the East. Catholicism is also the only religion in-game to feature the papacy mechanic.
