I guess you have heard of the notion of guardian angels before. Those who believe in guardian angels state that every Christian has an angel assigned to them by God to care and protect them. This belief is not recent. Church history shows that it dates back so many centuries ago. In fact, some early Church Fathers like Origen and Chrysostom in third and fourth centuries respectively believed and taught about guardian angels.
Those who advocate for the belief in guardian angels cite Matthew 18:10 and Acts 12:15 as their biblical basis. In the first verses of Matthew 18, Jesus speaks to his apostles about humbling themselves like children. Then he later says to them: “See that you do not despise one of these little ones. For I tell you that in heaven their angels always see the face of my Father who is in heaven” (10).
In the first verses of Acts 12 we find Jesus’ disciples praying in the house of Mary (the mother of John Mark) for Peter who has been put in prison by the Jewish religious and government leaders. However, when a girl reports to them that Peter is released from prison and is standing outside the house in which they were in, the disciples disbelieve her and say, “You are out of your mind.” But the girl insists but still they dismiss her and say, “It is his angel!” (15).
Now, do these verses teach that each Christian has a particular guardian angel? I do not believe so. In the case of Matthew 18:10, we should understand the “little ones” and “their angels” in a collective sense rather than individualistic sense. In other words, the verse states that angels who minister to these little ones and can also minister to every believer see the face of God the Father (not a particular angel of a particular little one sees the face of God the Father). In the case of Acts 12:15, we should understand it to mean that the believers thought that at this particular time God had sent this angel to probably encourage them and they referred to this angel as “Peter’s angel” implying an angel that was sent to them for the cause of Peter whom they were praying for.
It is important to guard against the belief of guardian angels because it can easily lead to the worship of angels which is prohibited in Scripture (Rev. 22:8, 9). Herman Bavinck observes, “The problem with the doctrine of guardian angels is that it leads to veneration and worship, a practice apparently referred to in Colossians 2:18.” If a believer is so occupied with the thoughts of a special angel who cares and protects them, they stand in danger of obliterating God in their minds as a sole sustainer and preserver of their lives and instead accredit this sustenance and preservation to an angel.
Having said this, it is important to point out that the Bible does teach that angels do minister to God’s people (but not a particular angel specifically for a particular Christian). Angels are ministering spirits (Heb. 1:14). So, God uses angels to help believers in various ways. For instance we read in Psalms 34:7 and 91:11 that they watch over believers. Angels also intervene is some special ways in some events of God’s people (Isaiah 63:9; Daniel 6:22; Acts 5:19). They also execute judgments against God’s enemies (Genesis 19:1, 13; 2 Kings 19:35; Matthew 13:41).
So, yes God uses his angels to help or minister to his people but God never sets aside or assign a particular angel to a particular Christian. This belief is hardly supported by Scripture and can easily lead to worship of angels which the Bible prohibits. I fully agree with the Belgic Confession Article 12 which clearly states: “He (God) also created the angels good, to be His messengers and to serve His elect (all believers).”
I also agree with John Calvin when he writes:
“But whether individual angels have been assigned to individual believers for their protection, I dare not affirm with confidence… Indeed, those who confine to one angel the care that God takes of each one of us are doing a great injustice both to themselves and to all the members of the church; as if it were an idle promise that we should fight more valiantly with these hosts supporting and protecting us round about!”
