I am not sure exactly what you mean Bushmaster, but I know that angel are mainly servants of God.
They either bring a message of Doom and calamity{ For we will destroy this place, because the cry of them is waxen great before the face of the LORD; and the LORD hath sent us to destroy it. Genesis 19:13}
Or they bring a message of Hope{And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people, Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters. Genesis 14:6,7}
God Bless!
