But nobody can get around what is written that Elizabeth addresses Mary as Mother of my Lord and I doubt anyone could argue context. It's pretty clear that that passage means what it says. Furthermore, who could not call her blessed? If they don't believe we should pray to her, then that is what they believe. The bible doesn't say explicitly one way or the other.
So then we get into sola scriptura and go round and round, endlessly, rancorously, and perhaps in the process condemn ourselves..
But who is the LORD that the Jewish, non Christian Elisabeth was referring to??? The bible isn't over 30,000 scriptures long for no reason...
