Aguardian angelis an angelthat is assigned to protect and guide a particular person, group, kingdom, or country. Belief in guardian angels can be traced throughout all antiquity. The concept of tutelaryangels and their hierarchy was extensively developed in Christianityin the 5th century by Pseudo- Dionysius the Areopagite.
The theologyof angels and tutelary spirits has undergone many refinements since the 5th century. Belief in both the East and the West is that guardian angels serve to protect whichever person Godassigns them to, [1]and present prayer to God on that person's behalf.The guardian angel concept is present in the books of the Hebrew Bibleand the Old Testament, and its development is well marked. These books described God's angels as his ministers who carried out his behests, and who were at times given special commissions, regarding men and mundane affairs. [2]
In Genesis 18-19, angels not only acted as the executors of God's wrath against the cities of the plain, but they delivered Lot from danger; in Exodus 32:34, God said to Moses: "my angel shall go before thee." At a much later period, we have the story of Tobias, which might serve for a commentary on the words of Psalm 91:11: "For He will command His angels concerning you to guard you in all your ways;" (Cf. Psalm 33:8 and 34:5)
The belief that angels can be guides and intercessors for men can be found in Job33:23-6, and in Daniel10:13 angels seem to be assigned to certain countries. In this latter case, the "prince of the kingdom of Persia" contends with Gabriel. The same verse mentions " Michael, one of the chief princes".In the New Testamentthe concept of guardian angel may be noted. Angels are everywhere the intermediaries between God and man; and Christ set a seal upon the Old Testament teaching: "See that you despise not one of these little ones: for I say to you, that their angels in heaven always see the face of my Father who is in heaven." (Matthew 18:10).
Other examples in the New Testament are the angel who succoured Christ in the garden, and the angel who delivered St. Peter from prison. In Acts12:12-15, after Peter had been escorted out of prison by an angel, he went to the home of "Mary the mother of John, also called Mark". The servant girl, Rhoda, recognized his voice and ran back to tell the group that Peter was there. However, the group replied: "It must be his angel"' (12:15). With this scriptural sanction, Peter's angel was the most commonly depicted guardian angel in art, and was normally shown in images of the subject, most famously Raphael's frescoof the Deliverance of Saint Peterin the Vatican.
Hebrews 1:14 says: "Are they not all ministering spirits, sent to minister for them, who shall receive the inheritance of salvation?" In this view, the function of the guardian angel is to lead people to the Kingdom of Heaven.
In the New Testament Epistle of Jude, Michael is described as an archangel.
