The Feast of all three Archangels is September 29. In the traditional calendar this was St. Michael’s feast day, with St. Gabriel’s being March 24th (the day prior to the Annunciation) and St. Raphael’s being October 24th. Communities which celebrate the Extraordinary Form of the Roman Rite still celebrate the three feasts.
The three archangels whom the Church honors by name are St. Michael, St. Gabriel, and St. Raphael. They are also the only three angels who are mentioned by name in Sacred Scripture.
St. Michael, St. Gabriel, St. Raphael (and Companions)
The Archangels are ranked in the lowest of the three Choirs of Angels but are some of the most prevalent in their interactions with mankind.
Sacred Scripture provides us with the names of three of the Archangels.
Michael is Hebrew for Who is Like God
“Then war broke out in heaven; Michael and his angels battled against the dragon. The dragon and its angels fought back” Revelations 12:7 [see also, Daniel 10:13, 21; 12:1; Jude 1:9]
Gabriel is Hebrew for Man of God, often rendered Strength of God
“In the sixth month, the angel Gabriel was sent from God to a town of Galilee called Nazareth, to a virgin betrothed to a man named Joseph, of the house of David, and the virgin’s name was Mary.” Luke 1:26-27
Raphael is Hebrew for God heals
“I am Raphael, one of the seven angels who enter and serve before the Glory of the Lord.” Tobit 12:15
From Tobit 12:15 the Church has deduced that there are seven archangels in all. Although various ecclesiastical traditions ascribe names to the remaining four, at places such as Polermo in Sicily and St. Michael’s Shrine in Tlaxcala, Mexico, these names vary from place to place and are not accepted by the Church for purposes of veneration by Catholics. Veneration of the Seven Archangels is permitted, however, and in Rome’s Basilica of Our Lady of the Angels and the Jesuit church Gesu there are chapels dedicated to the 7 archangels.
