The three Archangels—Michael, Gabriel, and Raphael—are the only angels explicitly named in Sacred Scripture, each playing a significant role in the history of salvation.

Saint Michael is known as the "Prince of the Heavenly Host," leading all the angels. His name, derived from Hebrew, means "Who is like God?" and was the rallying cry of the faithful angels against Lucifer and his followers during their rebellion against God. He appears four times in the Bible: in Daniel 10 and 12, the Letter of Jude, and Revelation.

Michael and his angels cast Lucifer and the evil spirits into Hell. He is invoked for protection against Satan and all forms of evil. In 1899, Pope Leo XIII, inspired by a prophetic vision foreseeing the evils that would befall the Church and the world in the 20th century, instituted a prayer to Saint Michael to be recited at the end of every Mass.

Christian tradition recognizes Saint Michael’s roles as the fighter against Satan, the rescuer of the souls of the faithful from the power of the enemy, especially at the hour of death, the champion of God’s people, and the guide who escorts souls from earth to divine judgment.

Saint Gabriel, whose name means "God is my strength," is mentioned four times in Scripture. Most notably, in the New Testament, he announced the birth of John the Baptist to his father Zacharias and foretold the Incarnation of the Word in Mary’s womb (Luke 1:19). Christian tradition also suggests that Gabriel appeared to Saint Joseph and to the shepherds and that he strengthened Jesus during His agony in the Garden of Gethsemane.

Saint Raphael, whose name means "God has healed," is primarily mentioned in the Book of Tobit (Tobit 12:15). He healed Tobias’ blindness and is traditionally associated with healing and acts of mercy. Raphael is also believed to be the angel described in John 5:1-4, who descended upon the pool and endowed its waters with healing powers, granting restoration to the first person who entered after the water was stirred.
