For the sisters, their garments are washed white and they are sanctified by virtue of the sacrifice of the great High Priest, Jesus Christ. For men, the priesthood is as necessary for exaltation as is baptism. Alma explains that for the men, sanctification comes as a blessing for honoring the priesthood. This doctrine is taught in the oath and covenant of the priesthood, For whoso is faithful unto the obtaining these two priesthoods of which I have spoken, and the magnifying their calling, are sanctified by the Spirit unto the renewing of their bodies (DC 84:33). This does not mean that they were sanctified by the priesthood, for Alma makes it clear that they were sanctified by the Holy Ghost.
