Angels are created spiritual beings — personal, rational, and moral — who serve as God's messengers, warriors, and ministers throughout Scripture. They are not divine, not human, not deceased believers, and not metaphors. They exist in a vast hierarchy (cherubim, seraphim, archangels, principalities, powers) and are wholly devoted to fulfilling God's purposes. Their primary role is not comfort to mankind but worship toward God and execution of His will. The "Angel of the LORD" in the Old Testament is widely understood as a pre-incarnate appearance of Christ (a Christophany). Holy angels never accept worship — only God is worshipped.
AN'GEL, n. A spirit, or a spiritual intelligent being employed by God to communicate his will to man. Angels are represented in Scripture as an order of beings superior to man, possessing greater wisdom and power, but ministering to God and to the heirs of salvation. The word is used for good and bad angels; the latter are called fallen angels, and are the angels of Satan. The word is sometimes used for men, as in Revelation chapters 1-3 (angels of the churches), and is applied to Christ, as the Angel of the covenant.
Contemporary culture has transformed angels into benign, gender-neutral comforters — decorations on greeting cards, spirit guides in New Age spirituality, or personifications of dead relatives "watching over us." None of this is biblical. Scripture presents angels as awesome, even terrifying, beings — their most common greeting is "Fear not!" precisely because their appearance provokes terror. The angel industry (books, trinkets, "angel communication") is spiritual confusion at best and demonic deception at worst.
