Litany of the Saints
The Litany of the Saints (Latin: Litaniae Sanctorum) is a formal prayer of the Roman Catholic Church as well as the Old Catholic Church, Anglo-Catholic communities, and Western Rite Orthodox communities. It is a prayer to the Triune God, which also includes invocations for the intercession of the Blessed Virgin Mary, the Angels and all the martyrs and saints upon whom Christianity was founded, and those recognised as saints through the subsequent history of the church. Following the invocation of the saints, the Litany concludes with a series of supplications to God to hear the prayers of the worshippers. It is most prominently sung during the Easter Vigil, All Saints' Day, and in the liturgy for conferring Holy Orders, the Consecration of a Virgin and reception of the perpetual vows of a religious or a diocesane hermit.
