As to the Catholic part, it is a discipline, a prudential judgment, applicable only to one rite, the Latin, of the Roman Catholic Church, reversible at will by any pope and please spare me the man-made rules response. He isn't telling you or your minister what to do. No Church document that I know of purports to tell you how to be a better Protestant.
With all due respect, you are so busy patting yourself on the back over your own imaginings of the meaning of Scripture, that you are missing the point. I am not insulting non-Catholics by saying that you ought not to criticize what you don't understand, but if you don't understand (and you don't), you don't understand.
I don't like fights between Christians in the presence of others (like on Free Republic). It gives aid and comfort to our mutual enemies. Can we give this a rest? Catholics are understandably a bit hair-trigger due to the relentless attacks by the usual gang of atheist media suspects. We don't need to hear what Jack Chick thinks while we are at it and I would not understand that if I heard it.
i always thought he was referring to lust.
