what is angel

An angel is a supernatural spiritual being who serves God in various theistic religious traditions. Angels are depicted as benevolent celestial intermediaries between God and humans in Abrahamic religions. According to Augustine of Hippo, the term angel refers to "the name of their office, not their nature", as they are pure spirits who act as messengers. Angels are beings who have greater power and ability than humans, and they exist in heaven or the spirit realm. Angels are ministering spirits, and they are sent out to serve for the sake of those who are to inherit salvation. Angels are the lowest of the celestial beings because they bring the divine message to us terrestrial creatures. The term "angel" denotes a function rather than a nature, and those holy spirits of heaven can only be called angels when they deliver some message.
