One might ask why such a study and why categorize the heavenly beings this way? I have tried to show that there are various types of spiritual beings working with and for the Heavenly Father and his elect. The main way these beings are categorized is by their appearances as well as their abilities, positions and purpose. These categories should help to give a better understanding and knowledge of heavenly beings. Mind you, I am not claiming to expose everything because I do not know all there is to know about them.
