In this work, the author drew on passages from the New Testament, specifically Ephesians 6:12 and Colossians 1:16, to construct a schema of three Hierarchies, Spheres or Triads of angels, with each Hierarchy containing three Orders or Choirs. In descending order of power, these were:
During the Middle Ages, many other schema were proposed, some drawing on and expanding on Pseudo-Dionysius, others suggesting completely different classifications. Here is another example, which is expanded in the rest of this article:
The Seraphim are the highest order of angels, serving as the caretakers of God's throne and continuously singing his praises. It is said that they surround the throne of God, singing the music of the spheres and regulating the movement of the heavens as it emanates from God.
The Cherubim are beyond the throne of God; they are the guardians of light and of the stars. It is believed that, although they are remote from men's plane of reality, their light still touch their lives; the divine light that they filter down from Heaven.
The Cherubim are thought by some as an order or class of angels, though
others hold them to be a higher class of heavenly beings than angels. Their rank among angels is uncertain, but they are always categorized in the First Sphere.
Many Christians believe that the Devil is a fallen angel that was among the Cherubim prior to his fall from Heaven. They believe that the Devil was considered as the angel of light before his sin against God.
The Cherubim are mentioned in Genesis 3:24 [1]; Ezekiel 10:17–20 [1]; and 1 Kings 6:23–28 [1].
The Archangels are usually considered the lowest order of the First Sphere; these angels tend the larger arenas of human endeavor and act as the administrative leaders of the Heavenly beings. An archangel is usually given a task of great importance to men. According to Pseudo-Dionysius the Areopagite's Angelology, however, the Archangels lie just above the lowest of the angel orders, the common Angels.
The word archangel is used only twice in the canonical Scripture—but several times in the Septuagint, once to refer to Michael the archangel
[1] and the other to who is believed to be Gabriel during the return of the Lord (Gabriel is preferred over Michael since he is the messenger angel). [1]
Christians who disagree that Satan was a cherub before his fall from heaven are more modern and believe that he was an archangel, basing this belief on the facts that
(a) the cherub that fell was a King on earth (sorry, I'm unable to find the verse that even says that a cherub had fallen); and
(b) the matchup in Revelation against the archangel Michael seems to show that he was an archangel [1]
And they also believe that his name was never Lucifer, but always Satan. [1]
Thrones are fully equal in authority and power in comparison to the Powers. However, Thrones are politically, militarily and economically oriented, and their main concerns revolve around people and world events. Thrones have authority over major divisions of the world.
Paul used the term thrones in Colossians 1:16 [1] but he may have used it to refer to the thrones of the kings of nations, instead of referring to angels.
The Angels are the lowest order of the angels, and the most familiar to men. They are the ones most concerned with human affairs. Within the category of angels, there are many different kinds, with different functions. The angels are sent as messengers to men.
