Just like with any large group of beings, Angels have a certain order or hierarchy. The different types of Angels are divided into different categories and have specific duties.
The Angel hierarchy consists of three larger levels known as “celestial spheres”, with each sphere containing three different groups of Angels called “choirs”.
These celestial spheres radiate outward with the inner circle containing the Angels closest to God while the outer levels contain the Angels closest to humans.
