While the exact amount of archangels is debated among different faiths, seven archangels supervise angels who specialize in different types of work helping humanity, and four of those are considered by many believers to be the most important archangels. They are Michael, Gabriel, Raphael, and Uriel.
Dominions or Lordships The "Dominions" (Eph. 1:21; Col. 1:16) (lat. dominatio, plural dominationes, also translated from the Greek term kyriotētes, pl. of kyriotēs, as "Lordships") or "Dominations" are presented as the hierarchy of celestial beings "Lordships" in some English translations of the De Coelesti Hierarchia.
Powers or Authorities. The "Powers" (lat. potestas (f), pl. potestates), or "Authorities", from the Greek exousiai, pl. of exousia (see Greek root in Eph 3:10). The primary duty of the "Powers" is to supervise the movements of the heavenly bodies in order to ensure that the cosmos remains in order.
Seraphim Angels Celebrating Holiness. Seraphim celebrate God's holiness and the joy of experiencing God's pure love by leading worship in heaven. They constantly speak and sing about their love for God. The Bible and Torah describe seraphim with wings flying around God's throne while calling out: "Holy, holy, holy is the Lord God Almighty.
Lastly, the thrones, symbolizing divine justice and judicial power, contemplate God’s power and justice. Reference to “thrones” is found in Colossians 1:16, and in Jewish apocryphal literature, the Book of Enoch and the Testament of Levi.
Virtues or Strongholds. These angels are those through which signs and miracles are made in the world. The term appears to be linked to the attribute "might", from the Greek root dynamis (pl. dynameis) in Ephesians 1:21, which is also translated as "Virtue" or "Power". They are presented as the celestial Choir "Virtues", in the Summa Theologica.
