Prayer of St. Augustine to the Holy Angels
O God, be propitious to me and guard me all the days of my life! be merciful unto me, and send to my aid thine Archangel, St Michael, that he may defend me against my enemies.
Holy Archangel, St Michael, protect me against all dangers, that I may not perish on the day of judgment.
By the grace thou hast merited, and through Our Lord Jesus Christ, the only Son of God, I beseech thee to deliver me from the perils of death.
St Gabriel, St Raphael, Holy Angels and Archangels, come to my aid. Virtues of heaven, be my help and my strength, that no enemy may be able to injure me either by water or by fire, or while journeying;
protect me from a sudden and unprovided death, and grant that, sleeping or waking, I may be freed from all danger.
