Baptisms for the dead often involve young people, ages twelve to seventeen. By appointment, they will spend two to three hours in the temple baptistery area, each person being baptized typically, for a score or more deceased persons. They dress in all-white baptismal clothing, attend a brief worship service, and then participate in the proxy baptisms. Those performing the baptism often include the adult male supervisors traveling with the group. It is understood that in the spirit world all persons for whom temple work by proxy is performed will have heard of the gospel and its ordinances
