what does the bible say?
Angelology is the section of systematic theology that focuses on the study of angels. Angelology also includes the study of fallen angels or demons, called Demonology, as well as the study of Satan, called Satanology. Angelology explores the nature of angels, their creation before the earth, and their various ranks and roles. It also examines their appearances throughout biblical history, the rebellion of some angels resulting in demons, and their participation in end-times events. Studying angels provides insight into God's sovereign plan and kingdom, encouraging believers to live with greater faith, to align their actions with God's will, and to adopt an eternal perspective.
