From the Book of Divine Worship - The Proper: First Part - Good Friday
The service concludes with the following prayer. No blessing or dismissal is added.
Lord Jesus Christ, Son of the living God, we pray you to set your passion, cross, and death between your judgment and our souls, now and in the hour of our death. Give mercy and grace to the living; pardon and rest to the dead; to your holy Church peace and concord; and to us sinners everlasting life and glory; for with the Father and Holy Spirit you live and reign, one God, now and for ever. Amen.
