An ordinance is a sacred, formal act that has spiritual meaning. Ordinances are performed by the authority of the priesthood and under the direction of those who hold priesthood keys. Ordinances help us remember who we are and remind us of our relationship with God. They help us come unto Christ and receive eternal life.
