If you agree that she is blessed among women, do you therefore agree that she is the most blessed woman ever?
Not at all, the bible doesn't say that.
Mary's faith is based on a signs, she saw, even conceived and carried, my faith is without signs. In that way I'm more blessed as Jesus said. My faith is more perfect because it is not based on seeing or being part of any signs.
John 20:29 Jesus said to him, “Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed.”
RC's want to say that Mary was picked because she was so blessed. The bible says she is Blessed because she got to be part of this sign not because of her sinless immaculate character. That is never stated or implied.
