It portrayed motherhood as the highest position that a woman could achieve. For God had made Mary neither a prophet nor the messiah nor the daughter of God. Nor did God take the form of a woman. She was only the womb. She was a perpetual virgin too, and she endured the vilest harassment because of it, or so the story went. Rebecca couldn’t relate to the Virgin Mary at all.
