No, no no Harley! You can’t start quoting scripture!
And whatever you do, don’t look to scripture where it compares circumcision to baptism. And uncircumcision, SKIP THAT PART! And definitely skip all that about human tradition, oh my! Too confusing without a inspired interpreter... (which none of the Catholics here are, unless that cheeky Freeper BennyXVI has finally unlurked.)
Rather turn to canon law, and the vast, unconfusing, unending and constantly revised, dust covered volumes of what the Roman Catholic Church has taught from the time of Peter the First (except when it didn’t... just ignore that part.)
