First, by “everyone” I’m going to say I mean for our discussion “Christians”. It’s another Bible study to see what role angels play in the lives of all people. That angels watch over and guard God’s people is clearly established in Scripture, though. Let’s look at Psalm 34:7, 91:11, 12, Hebrews 1:14 and 2 Kings 6:8-19 for an example of this. So our question is not if God uses angels to defend us. He does! But our question is do we individually have an angel assigned to us from, say, our baptism as our spiritual birth into the family of God?
The belief of specific guardian angels may be indicated by Matthew 18:10; Jesus talks here of children having specific angels (giving rise to the belief in secular circles of fairy godparents that watch over young children). Nothing more is indicated, however, by this verse. The belief in individual guardian angels can be traced further back to Jewish sources (and even pagan – Greek philosophers and Zoroastrian priest taught of angelic guardians of man). Let’s look at Job 33:23-26 to see a case for a possible individual angelic intercessor. Several Church Father such as Jerome, Clement of Alexandria and Pseudo-Dionysius and later theologians such a Thomas Aquinas and Duns Scotus supported the belief in specific guardian angels for Christians. Martin Luther asserted in one writing that the angels God assigned to men differed in rank and ability, as did the men themselves. Luther wrote, “Just as among men, one is large and another small, and one is strong and another weak, so one angel is larger, stronger, and wiser than another. Therefore, a prince has a much larger and stronger angel, one who is also shrewder and wiser, than that of a count, and the angel of a count is larger and stronger than that of a common man. The higher the rank and the more important vocation of a man, the larger and stronger is the angel who guards him and holds the Devil aloof.” Otherwise, Luther in his morning and evening prayer spoke only of “the angels having charge over us that the evil foe have no power over us”.
If each Christian has a single guardian angel assigned through life, it is not clearly established in the Bible. It is, probably, and innocent belief as reflected by the many who believe this. There is a danger lurking in this belief, however. We are never to worship angels nor to pray to them. Such is reserved for God. “You shall worship the Lord your God and Him only shall you serve,” said Jesus against Satan (Matthew 4:10b). Paul warns the Colossians against the worship of angels (Col. 2:18). Sometimes they can talk to us as God’s messengers but never are we to worship them (Revelation 22:8, 9).
