The Saints: Michael, Gabriel and Raphael
These archangels, messengers sent by God, are the only ones named in the Bible.
Michael is patron of the sick, radiologists and mariners. Gabriel explains Daniel’s visions to him in the Book of Daniel, and in the Gospel of Luke announces to Zechariah and Mary the births of their respective sons. He is the patron of messengers and telecommunications and postal workers. Raphael guides Tobiah in the Book of Tobit; he is patron of the blind, physicians and travelers.
The church created their joint feast after the Second Vatican Council.
