Feast day of Guardian Angels

St. Thomas Aquinas on Guardian angels.

113. ANGEL GUARDIANS

1. It is fitting that changeable and fallible human beings should be guarded by angels, and thus steadily moved and regulated to good.

2. St. Jerome, in his commentary on Matthew 8:10, says "The dignity of human souls is great, for each has an angel appointed to guard it." God's providence extends, not only to mankind as a whole, but to individual human beings. Each human being has, by God's loving providence, his own guardian angel.

3. It seems that the office of being guardians to men belongs to the lowest order of heavenly spirits, that is, the ninth order, the order of Angels.

4. Each human being, without exception, has a guardian angel as long as he is a wayfarer, that is, during his whole earthly life. In heaven a man will have an angel companion to reign with him, but not a guardian; no guardian is needed when the guarded journey has been successfully completed. In hell, each man will have a fallen angel to punish him.

5. Each human being has his guardian angel from the moment of his birth, and not, as some have taught, only from the moment of baptism.

6. The guardian angel is a gift of divine providence. He never fails or forsakes his charge. Sometimes, in the workings of providence, a man must suffer trouble; this is not prevented by the guardian angel.

7. Guardian angels do not grieve over the ills that befall their wards. For all angels uninterruptedly enjoy the beatific vision and are forever filled with joy and happiness. Guardian angels do not will the sin which their wards commit, nor do they directly will the punishment of this sin; they do will the fulfillment of divine justice which requires that a man be allowed to have his way, to commit sin if he so choose, to endure trials and troubles, and to suffer punishment.

8. All angels are in perfect agreement with the divine will in so far as it is revealed to them. But it may happen that not all angels have the same revelations of the divine will for their several ministries, and thus, among angels, there may arise a conflict, discord, or strife. This explains what is said in Daniel 10:13 about the guardian angel of the Persians resisting "for one and twenty days" the prayer of Daniel offered by the Archangel Gabriel.
