We know that Mary, the mother of Jesus, was an elect woman and “chosen vessel.”
Members of The Church of Jesus Christ of Latter-day Saints (also known as Mormons) believe that holy scripture describe not only who she was and some of the things she did, but also provide information on her holy calling.
