What's the Difference Between Orthodox and Catholicism?

i still the preponderance of the evidence on the whole, is greater for catholicism. The office of the papacy provides a very important unity to the hurch. Could you give me an example of what the pope could do that would invalidate catholicism? I don't know if he a, if he reversed a munifitisimus deus, or a the bull on the immaculate conception, and just said, never mind.
