I believe we can honor Mary as the mother of Christ without having to believe that she was the only human being born without sin (Immaculate Conception), lived a totally sinless life, was assumed into heaven miraculously, is Queen of Heaven, etc., etc. There are only two references to her in the Gospels between Christ's childhood and crucifixion, and both raise questions. Reread John 2:4, for example. As for her perpetual virginity, I don't see that as essential, and Matt. 1:25 suggests that she and Joseph may have lived quite normally as husband and wife. No problem. Love-making is a gift from God.
The whole story of her parents, Anne and Joachim, is not found in the Bible - not even their names - so that raises questions, too.
But isn't becoming the mother of Christ quite enough to make her 'blessed among women'? Why is it necessary to add and add and add to her accolades?
