One thing from the article that should be cleared up.  The RCC does not speak with authority.  They speak with authoritarian ideas of control.  We should never mix up those two words.  We are all finite humans, thus we all make mistakes.  No man or group of men (or women) have or ever will speak with infallibility.  For to do so is to worship the golden self-calf.  It is in short idolatry.
