Today is the feast day of Sts Michael, Gabriel, and Raphael, Archangels. They are mentioned by name in Sacred Scripture in the books of Tobit, Daniel, Luke, 1 Thessalonians, Jude, and Revelation.
The Catechism of the Catholic Church tells us, “…the whole life of the Church benefits from the mysterious and powerful help of angels.” John Paul II, in a General Audience, reminds us that the name of each Archangel reflects a facet of the nature of God. St. Michael’s name means ‘Who is like God?,’ St. Gabriel’s ‘power of God,’ and St. Raphael’s ‘God heals.’ To angels, God has entrusted a special mission with human beings at the center.
