“The sacrament is the most oft-repeated ordinance for us personally in mortality. Other ordinances of exaltation are performed for us personally only once in our lifetime (baptism, confirmation, temple endowment, and sealing). But with the sacrament, all worthy persons may participate in a personal, intimate way, as often as it is administered by those who are authorized.”
