Governing

May your continual pity, O Lord, cleanse and defend Your Church; and, because without you she cannot endure in safety, may she ever be governed by Your bounty. Through our Lord Jesus Christ, Your Son, Who lives and reigns with You in the unity of the Holy Spirit, God, world without end. Amen.
