Scripture doesn’t even talk about Mary’s mom. Does that mean she never existed?
No, but it also doesn’t mean that the Roman Catholic Church can make up whatever it wants to about her, teach it, and then claim, “there is nothing in the Scripture that (insert rebuttal here)!”
That is what has been done. Same with Mary’s supposed sinlessness, Peter as the first pope, and so forth.
When we’re admonished to not add to God’s word, this sort of supposition, or ourtright falsehoods, is also what we’re warned against.
