I agree with you. I actually had this conversation with a Catholic priest when I had to justify why I should be allowed to be married in a Catholic church as a Protestant. I just said to him, “We both believe that Jesus Christ is our savior. The rest of it is just how you acknowledge that according to scripture.” He went completely silent for about 5 seconds and then said, “Clearly you have a faith based background.” We argue over the dumbest stuff.
