In Mormonism, members of the Church of Jesus Christ of Latter-day Saints believe in taking the sacrament. The sacrament was first established by Jesus himself, on the night of the passover. In Moroni in the Book of Mormon, it also talks about the sacrament after Jesus came to the America's. It has the sacrament prayer in Moroni.
The sacrament consists the representation of Jesus's body and blood. The breaking of the bread and partaking of it represents how Jesus's body was broken. Wine (grape juice) or more commonly water represents Jesus's blood, and how he bled out of every pore at the garden of Gethsemane.
The members who partake of the sacrament have to be worthy to do so.
The priests in the church bless the bread and water, then give it to the deacons and teachers in trays to the members to partake of the sacrament.
