That Catholic doctrine is trinitarian and the protests about Mary are a cover for Arianism other doctrines that reject the doctrine of the Incarnation.
That Catholic doctrine is their own and it's meant to oppose God's Word and it does. HIS WORD is the final authority. Not man's word.
If HIS WORD isn't one's final authority - then they don't belong to HIM because they listen and obey 'another'. Satan has his own kingdom disguised as 'religious' and w/all the words and pomp to deceive.
That's interesting; but what it to do with what we were talking about?
