So, your contention is that, "all generations shall call me blessed" (Luke 1:48) IS NOT in the Bible? Or do you know that it is there and steadfastly disobey it? As far as I know, that phrase (possibly "modernized" but still containing the word "blessed") appears in EVERY Protestant translation. So, why the uneasiness about following the dictates of scripture?
If anybody ever lights a match on this thread all these straw men will turn into a blazing inferno.
I didn't see anyone insisting that I was a heretic because I didn't call her blessed. But if it helps, then she is Blessed. That is not a title, BTW, but simply a statement of fact. Show me anywhere in scripture where she was called "The Mother of God". Show me where I must use that "Title" or be considered a heretic.
She is the Mother of Jesus. That is a unique title. Her calling was indeed unique, but she was a human being just like the rest of us. A mere mortal.
Other people are called Blessed. That is not a unique title.
