A molieben (also called a moleben, service of intercession, or service of supplication) is a supplication prayer service in honor of either our Lord Jesus Christ, the Mother of God, or a particular saint or martyr. It is a Russian Orthodox tradition and only an ordained priest can celebrate it.
It is the custom to celebrate a molieben service only in honor of a glorified saint.
