On Tuesday, Pope Benedict released his first major policy initiative: an instruction that states that men with deep-seated homosexual tendencies could not be priests, while those with transitory tendencies could be, thereby proving the transitive property of gayness.
[If Priests = B, and B = Gay ∴ Priests = Gay]
I'll give you a little... I'll give you a little time there, for those of you who don't remember your high school geometry.
Now, what's the difference between "transitory" homosexuality and "deep-seated" homosexuality?
