Want to know something funny? The bible describes catholicism as the "great harlot" (read the description of the great harlot in Revelation and Daniel- headquarters is in a place famous for seven hills, the colors are the same ones worn by the leaders, the history aligns with the prophecy, etc.). So how much would you trust the Pope knowing that the book he claims to be the basis of his belief foretells of his religion being an oppressor and the religion where the false profit originates from in the "end times".
Oh and for a really good laugh, compare catholicism to the pegan worship of Mithra (which was eradicated by the Catholic church, nearly without opposition, about the time catholicism became a government power in Rome about 4th century A.D.). Even the hat worn has the same name as the catholic Mitre. >:D
