Vespers is the evening prayer service in the Western Catholic, Eastern Catholic, and Eastern Orthodox, Anglican, and Lutheran liturgies of the canonical hours. The word comes from the Greek and the Latin vesper, meaning "evening". The term is also in limited use in some Protestant denominations to describe evening services. It is also referred to in Anglican circles as Evening Prayer. Vespers opens with the singing or chanting of the words Deus, in adiutorium meum intende. Domine, ad adiuvandum me festina. Gloria Patri, et Filio, et Spiritui Sancto. Sicut erat in principio, et nunc et semper, et in saecula saeculorum. Amen. Alleluia.
