Marian litany
In Christian worship, Marian litany is a form of prayer to Mary, mother of Jesus used in church services and processions, and consisting of a number of petitions. In the Eastern Church litanies are always a part of the official liturgy, and they have at least three different forms: Synaptae (Collect), Ektenie ("intense" prayer of intercession and pardon based in part on Psalm 50) and Aitaesis (intercessory prayer for peace, pardon and protection).
