Members of The Church of Jesus Christ of Latter-day Saints are commanded to partake of the sacrament each week (see D&C 59:9, 12). When the priest offers the scriptural prayer on the bread, he prays to God, the Eternal Father, that all who partake may “witness unto thee . . . that they are willing to take upon them the name of thy Son” (D&C 20:77; Moro. 4:3). This renews the covenant made in the waters of baptism that we will take upon us the name of Jesus Christ and “serve him and keep his commandments” (Mosiah 18:10). In modern scriptures persons desiring to be baptized are required to witness before the Church “that they have truly repented of all their sins, and are willing to take upon them the name of Jesus Christ, having a determination to serve him to the end” (D&C 20:37; see also 2 Ne. 31:13; Moro. 6:3).
