"For Latter-day Saints, the ultimate sealing power is the priesthood power given to authorized servants of the Lord to perform certain acts on earth and have them recognized (sealed) or validated in heaven. They believe it is this authority the Lord Jesus Christ described when he said to Peter, "I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven" (Matt. 16:19)."
Belief of mormonism is that a covenant such as marriage "for eternity", when "sealed" in the mormon temple "binds in Heaven what is bound on earth".
