I'm fully with you on this. That being the case, why do folks continue with the misnomer that the RCC is a Christian church? We make no such accommodation for the Mormons or Jehovah Witnesses.
Alas, the RCC is not alone in this position. Consider certain Protestant churches that merit the same consideration. First to mind is the Episcopal denomination.
How far away from the narrow path of Truth can someone wander before he is on a different road?
I really don’t know. They should just come out and admit what they are up to. The Popes all say it right out don’t they? The Truth will set them free. Then the people who want to worship Christ can form their own church and those who want to worship Mary and the saints can go have theirs. It seems so logical, rather than all this angst and double-talk they got going on
