One Angel is spirit creature that dwells in the sky and has the function of messenger between God and human beings.
The word angel comes from the Greek term aggelos which means messenger, and they are heavenly beings created by God to be messengers. They have no will of their own, that is, they do not have free will like Man, and are created with the sole purpose of giving glory and fulfilling God's will.
According to angelology, angelic beings are: seraphim, cherubim, thrones, dominations, virtues, powers, principalities, archangels and angels. St. Thomas Aquinas divided celestial beings into three spheres. The first is made up of seraphim, cherubim and thrones. The domains, virtues and powers are part of the second sphere. The third sphere is made up of archangels and angels.

In the context of the arts, angels were depicted in human form and with wings, to give them a less earthly and more supernatural appearance. Many angels are represented as children.
