The Blessed Sacrament, also Most Blessed Sacrament, is a devotional name to refer to the body and blood of Christ in the form of consecrated sacramental bread and wine at a celebration of the Eucharist. The term is used in the Latin Church of the Catholic Church, as well as in Anglicanism, Lutheranism, Methodism, and the Old Catholic Church, as well as in some of the Eastern Catholic Churches. In the Byzantine Rite, the terms Holy Gifts and Divine Mysteries are used to refer to the consecrated elements. Christians in these traditions believe in the Real Presence of Jesus Christ in the Eucharistic elements of the bread and wine and some of them, therefore, practice Eucharistic reservation and adoration. This belief is based on interpretations of both scripture and sacred tradition. The Catholic belief has been defined by numerous ecumenical councils, including the Fourth Lateran Council and the Council of Trent, which is quoted in the Catechism of the Catholic Church (which explains the meaning of transubstantiation).
