sacrament definition

A religious ceremony or rite. Most Christian churches reserve the term for those rites that Jesus himself instituted, but there are disagreements between them on which rites those are. The Lutheran Church, for example, maintains that baptism and Communion are the only sacraments, whereas in the Roman Catholic Church and the Eastern Orthodox Church, there are five more: confirmation; confession; anointing of the sick; the ordination of clergy; and the marriage of Christians.
