Sunday services for members of The Church of Jesus Christ of Latter-day Saints (Mormons) consist of a three-hour block of time divided into three segments. The primary Sunday service is Sacrament Meeting, which is slightly more than an hour in length, and is attended by the combined congregation. Sacrament Meeting services consist of the Aaronic Priesthood blessing and passing the sacrament--consecrated bread and water in remembrance of the body and blood of Christ--to members of the Church.
