One is either a Catholic
Or a follower of Jesus Christ and HIS WORD for Jesus is THE LIVING WORD. NO ONE can trump that.
Now now, let them keep trying. It’s entertaining.
Hilaire Belloc said "One is either a Catholic or anything that they want to be". A Protestants religion is doing what they want to do and maybe finding some conveniently interpreted scripture, as they want to see it, to justify themself. In other words they are what they want to be, their religion is a mirror image of themselves.
Let's get to where the rubber meets the road, LIVING the faith (by their deeds you shall know them):
Do you believe that, whether people partake in impure touching, fornicate before marriage, shack up, marry civil only, use contraceptives, divorce from a marriage before God, abort children conceived in a rape, watch immoral programs and movies like Desperate Housewives, watch pornography, go to strip clubs, go to the beach to look at the naked girls... ITS ALL OK FOR THEM, as long as they have a relationship with Christ, they are all saved?
Ah, so you include Mormons and JWs?
