Perhaps Christianity should be retitled as protestant(ism?), since, as Moriarty more or less mentioned, catholocism is simply a subcategory of Christianity. Probably removal of Magic, since it's more a part of certain religions, than a religion itself. One could perhaps replace it with Ceremonial Magic, or ceremonialism, which would cover lots of stuff like Thelema and the Order of the Golden Dawn and other such things. One could then, in theory, proceed to remove Wicca, since the two primary flavors of Wicca tend to fall under either Paganism (even though it's a rather generalistic term, it works) or Ceremonialism, (the original Wicca was founded by a member of the golden dawn as I recall, or at least heavily based on it)

Yah... I probably thought abou this just a bit to much... eh well...
