" One who uses the morning prayer from A Manual of Eastern Orthodox Prayers will not only begin each day with the sign of the cross and an invocation of the Trinity, but will next say this: God, be merciful to me, a sinner. And then there follows a prayer to the Holy Spirit: O Heavenly King, O Comforter, the Spirit of truth, who are everywhere and fillest all things, the treasure of blessings, and giver of life, come and abide in us. In truth Orthodox fashion, the next sentence brings back the matter of sin: Cleanse us from all impurity, and of thy goodness save our souls. "
