Today is the Feast of the Archangels Michael, Gabriel and Raphael. The Church has a rich history-filled archive of devotions, prayers, practices, and liturgical traditions dedicated to these mighty spirits, and a simple Google search will yield a fantastic amount of information and devotions for personal prayer and meditation.
A few ideas for your consideration:
Read the Book of Tobit. It's one of the shorter books in the Bible and tells the fascinating and charming story of St. Raphael's appearance and guidance to Tobit's son Tobiah and his family.
Recite the Angelus in honor of St. Gabriel. This prayer reminds us of the important role this archangel played in the mystery of the Incarnation, and how Mary's simple response set into motion the greatest event the world has ever experienced.
Read and meditate on G.K. Chesterton's famous poem, "To St. Michael in Time of Peace" (see below), first published in 1929. It will renew your fervor and love toward this Prince of Angels.
Have a wonderful, angel-inspired day!
To St. Michael in Time of Peace
Michael, Michael: Michael of the Morning,
Michael of the Army of the Lord,
Stiffen thou the hand upon the still sword, Michael,
Folded and shut upon the sheathed sword, Michael,
Under the fullness of the white
Gird us with the secret of the sword.
When the world cracked because of a sneer in heaven,
Leaving out for all time a scar upon the sky,
Thou didst rise up against the Horror in the highest,
Dragging down the highest that looked down on the Most High:
Rending from the seventh heaven the hell of exaltation
Down the seven heavens till the dark seas burn:
Thou that in thunder threwest down the Dragon
Knowest in what silence the Serpent can return.
Down through the universe the vast night falling
(Michael, Michael: Michael of the Morning!)
Far down the universe the deep calms calling
(Michael, Michael: Michael of the Sword!)
Bid us not forget in the baths of all
In the sigh long drawn from the frenzy and the fretfulness
In the huge holy sempiternal silence
In the beginning was the Word.
