Some branches of Christian theology have proposed a nine-level hierarchy of angels as follows:

• Highest/First Order:
Seraphim
Cherubim
Thrones

• Middle/Second Order:
Dominions
Virtues
Powers

• Lowest/Third Order:
Principalities
Archangels
Angels [1]

The difficulty is that the Bible identifies no such hierarchy of angels. In the Bible we see that there could be different kinds of angels, and, if there are different kinds, there might be some sort of hierarchy. If a hierarchy exists, the Bible does not tell us about it explicitly. If it were important for us to know about it, the Bible would have told us. The term angel simply means “messenger” and emphasizes the work that angels do.
