The angels are many, hierarchically arranged into nine choirs according to their different callings and responsibilities. They are, from the highest realms to the lower realms: the seraphim, also called “the burning ones” who attend God’s throne and constantly praise Him with the highest love, the cherubim, whose name means “fullness of wisdom,” and the thrones, who represent God’s power and authority.
The final choir, the angels, also known as the guardian angels, are the closest and most directly involved with humans. They watch over individuals, protecting, guiding, and communicating God’s love and grace.
