Angels on Assignment - Types of Angels

And suddenly there was with the angel a multitude of the heavenly host praising God, and saying, Glory to God in the highest, and on earth peace, good will toward men.

The "Archangel" Gabriel - telling the shepherds a Savior is born (Luke 2:9) - other Luke 1:11-38, Dan 8:15–26, 9:21–27,

Warring Angels - from Rev 12 depicting the War in Heaven - which many believe already took place a long time ago

Seraphim - the Four Living Creatures - Holiness Angels - the burning ones (Isaiah 61-3, Ezek 1-2, Revelation 4:6–9; 5:6–14; 6:1–8; 14:3; 15:7; and 19:4)

Messenger Angels

Mixed appearance. Like the Seraphim, in Heaven there are animal, and "half-human-half-animal" like beings. In Isaiah, Ezekiel and Rev we hear of similar creatures. There are also other hybrids between human-like and animals. If we see these in Greek "mythology" (centaurs, minotaurs, mermaids, etc) it is because they were in Heaven before the rebellion, and some there still. In his book "In Heaven" by Dean Braxton, he says he saw a creature in Heaven like this whose name was "Righteousness".

Miracle Angel - from The Fiery Furnace with Shadrach, Meshach, and Abednego (Dan 3:8)

Mixed beings. In Rev 4, we hear of unusual beings called Seraphim. The centaur like we see in Narnia, likely exists as a being in Heaven as well. The devil does not create. He comes to steal, kill & destroy John 10:10. If these exist as Greek gods, you can bet we'll see them in Heaven.

Gatekeeper Angels - block or allow access through gates, doorways and portals much like the cherubs who guarded the entrance to the Garden of Eden after Adam & Eve left. This image was of the retelling of Tony Kemp's visit to Heaven on Sid Roth.
