...the perfect evening prayer:
After marking yourself with the sign of the holy cross at the invocation, confess the Creed, and pray the Our Father, then say:
I thank You, my heavenly Father, through Jesus Christ, Your dear Son, that You have graciously kept me this day; and I pray that You would forgive me all my sins where I have done wrong, and graciously keep me this night. For into Your hands I commend myself, my body and soul, and all things. Let Your holy angel be with me, that the evil foe may have no power over me. Amen.
