Angel

Three angels, in a picture made in about 1420 by the Russian, Andrej Rublev.

In many religions, an angel is a good spirit. The word angel comes from the Greek word angelos which means "messenger". Angels appear frequently in the Old Testament, the New Testament, and the Qur'an. In all of these, angels appear like humans. In Christianity angels are helpers of god who are ministers to the faithful.

Angels do have the ability to sin. Satan & a third of the angels rebelled against God & were cast out of heaven, creating the demon world.

In the Bible angels often punished peoples for their sins. They tested people's faith in God. They are often depicted in art as having wings and a halo. The wings represent their speed, and the halo represents their holiness. Angels named in the Bible are Michael and Gabriel and Raphael.
