Prayer of St. John Chrysostom
to Guardian Angels for Spiritual Protection

Lord, stretch out Your mighty hand and Your sublime and holy arm, and in Your watchful care look down upon me, Your creature, and send down upon me a peaceful angel, a mighty angel, a guardian of soul and body, who will rebuke and drive away every evil and unclean demon from me. For You alone are Lord, Most High, almighty and blessed unto ages of ages. Amen.
