Abrahamic religions often depict them as benevolent celestial intermediaries between God (or Heaven) and humanity.[1][2] Other roles include protectors and guides for humans, and servants of God.[3] Abrahamic religions describe angelic hierarchies, which vary by sect and religion. Some angels have specific names (such as Gabriel or Michael) or titles (such as seraph or archangel). Those expelled from Heaven are called fallen angels, distinct from the heavenly host.

Angels in art are usually shaped like humans of extraordinary beauty.[4] They are often identified in Christian artwork with bird wings,[5] halos,[6] and divine light.
