Angels are pure spirits that were created by God. The roles and missions of the angels in God's plan are numerous, as one may gather by reading the Holy Bible.

The Angel Gabriel declared to Mary that she would conceive and give birth to the Son of the Most High (cf. Lk 1, 26-38), and that an Angel revealed to Joseph the supernatural origin of Mary's conception (cf. Mt 1, 18-25); the Angels appear to the shepherds in Bethlehem with the news of great joy of the Saviour's birth (cf. Lk 2, 8-24); "the Angel of the Lord" protected the infant Jesus when he was threatened by Herod (cf. Mt 2, 13-20); the Angels ministered to Jesus in the desert (cf. Mt 4, 11) and comforted him in his agony (Lk 22, 43), and to the women gathered at the tomb, they announced that he had risen (cf. Mk 16, 1-8), they appear again at the Ascension, revealing its meaning to the disciples and announcing that "Jesus ...will come back in the same way as you have seen him go" (Acts 1, 11).

There are nine choirs of angels are: Seraphim, Cherubim, Thrones, Dominions, Virtues, Powers, Archangels, Principalities and Guardian Angels.

The Seraphim are the highest order of angels, while the Guardian Angels are those closest to humanity. Every person is personally assigned a Guardian Angel by God at the moment of conception. Our guardian angels protect us, guide us and present our prayers before the Throne of God.

St. Thomas teaches us (Summa Theologica I:113:4) that only the lowest orders of angels are sent to men, and consequently that they alone are our guardians. Not only the baptized, but every soul that cometh into the world receives a guardian spirit. Our guardian angels can act upon our senses and upon our imaginations -- not, however, upon our wills, except "per modum suadentis", viz. by working on our intellect, and thus upon our will, through the senses and the imagination.

"How great the dignity of the soul, since each one has from his birth an angel commissioned to guard it." – St. Jerome, 4th century

Pray to your Guardian Angel
Angel of God,
my guardian dear,
To whom God's love
commits me here,
Ever this day,
be at my side,
To light and guard,
Rule and guide.

Amen.
