Angelology, coming from the Greek words angelos (meaning messenger) and logos, (meaning word), is the study of the doctrine of angels. The Greek word angelos (and the Hebrew equivalent malʾāk) has the generic meaning of messenger, and can refer in Scripture to both human messengers and spirit beings. The English term angelology, however, is normally restricted to refer to those “ministering spirits” that are the messengers of the Lord of Hosts. While Scripture does not encourage excessive speculation on the matter, believers are given the assurance that these messengers are, because of Christ, at constant work on their behalf. As the first chapter of Hebrews makes clear, it is His Person and work that must always be our focus.
