was foreordained. There is only one Mary, even as there is only one Christ. We
may suppose that she was more highly endowed spiritually than any of her mortal
sisters, but with it all, she was a mortal, not a God. Her mission was to bring

privilege, being mortal, to bring into the world Him by whom immortality should
come. And blessed is she forever! (Bruce R. McConkie, The Promised Messiah,
446)
