Feast of Saints Michael, Gabriel, and Raphael, Archangels

The name Michael means "who is like God."

Saint Michael the Archangel, defend us in battle, be our protection against the wickedness and snares of the devil; may God rebuke him, we humbly pray and do thou, O Prince of the heavenly host, by the power of God, thrust into hell Satan and all evil spirits who wander through the world for the ruin of souls. 
Amen.

Raphael means "God is my health."

O God who in Thy ineffable goodness hast rendered blessed Raphael the conductor of thy faithful in their journeys, we humbly implore Thee that we may be conducted by him in the way of salvation, and experience his help in the maladies of our souls. Through Jesus Christ, Our Lord. Amen.

Gabriel means "God is my strength." 

Prayer to St. Gabriel, for Others

O loving messenger of the Incarnation, descend upon all those for whom I wish peace and happiness. Spread your wings over the cradles of the new-born babes, O thou who didst announce the coming of the Infant Jesus.

Give to the young a lily petal from the virginal scepter in your hand. Cause the Ave Maria to re-echo in all hearts that they may find grace and joy through Mary.

Finally, recall the sublime words spoken on the day of the Annunciation-- "Nothing is impossible with God," and repeat them in hours of trial--to all I love--that their confidence in Our Lord may be reanimated, when all human help fails. 
Amen.
