Introduction
The fact that God has created a realm of personal beings other than mankind is a fitting topic for systematic theological studies for it naturally broadens our understanding of God, of what He is doing, and how He works in the universe.
We are not to think that man is the highest form of created being. As the distance between man and the lower forms of life is filled with beings of various grades, so it is possible that between man and God there exist creatures of higher than human intelligence and power. Indeed, the existence of lesser deities in all heathen mythologies presumes the existence of a higher order of beings between God and man, superior to man and inferior to God. This possibility is turned into certainty by the express and explicit teaching of the Scriptures. It would be sad indeed if we should allow ourselves to be such victims of sense perception and so materialistic that we should refuse to believe in an order of spiritual beings simply because they were beyond our sight and touch.1
The study of angels or the doctrine of angelology is one of the ten major categories of theology developed in many systematic theological works. The tendency, however, has been to neglect it. As Ryrie writes,
One has only to peruse the amount of space devoted to angelology in standard theologies to demonstrate this. This disregard for the doctrine may simply be neglect or it may indicate a tacit rejection of this area of biblical teaching.

Every reference to angels is incidental to some other topic. They are not treated in
