O God, who dispose in marvelous order ministries both angelic and human, graciously grant that our life on earth may be defended by those who watch over us as they minister perpetually to you in heaven. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever.

Saints Michael, Gabriel and Raphael
Angels—messengers from God—appear frequently in Scripture, but only Michael, Gabriel and Raphael are named.
Michael appears in Daniel's vision as "the great prince" who defends Israel against its enemies; in the Book of Revelation, he leads God's armies to final victory over the forces of evil. Devotion to Michael is the oldest angelic devotion, rising in the East in the fourth century. The Church in the West began to observe a feast honouring Michael and the angels in the fifth century.
Gabriel also makes an appearance in Daniel's visions, announcing Michael's role in God's plan. His best-known appearance is an encounter with a young Jewish girl named Mary, who consents to bear the Messiah.
Raphael's activity is confined to the Old Testament story of Tobit. There he appears to guide Tobit's son Tobiah through a series of fantastic adventures which lead to a threefold happy ending: Tobiah's marriage to Sarah, the healing of Tobit's blindness and the restoration of the family fortune.
The memorials of Gabriel (March 24) and Raphael (October 24) were added to the Roman calendar in 1921. The 1970 revision of the calendar joined their feasts to Michael's.
Each of these archangels performs a different mission in Scripture: Michael protects; Gabriel announces; Raphael guides. Earlier belief that inexplicable events were due to the actions of spiritual beings has given way to a scientific world-view and a different sense of cause and effect. Yet believers still experience God's protection, communication and guidance in ways which defy description. (www.americancatholic.org/saintoftheday)
