The Bible mentions the Thrones angelic rank (as well as the principalities and dominions) in Colossians 1:16:
“𝘍𝘰𝘳 𝘣𝘺 𝘩𝘪𝘮 [𝘑𝘦𝘴𝘶𝘴 𝘊𝘩𝘳𝘪𝘴𝘵] 𝘸𝘦𝘳𝘦 𝘢𝘭𝘭 𝘵𝘩𝘪𝘯𝘨𝘴 𝘤𝘳𝘦𝘢𝘵𝘦𝘥, 𝘵𝘩𝘢𝘵 𝘢𝘳𝘦 𝘪𝘯 𝘩𝘦𝘢𝘷𝘦𝘯, 𝘢𝘯𝘥 𝘵𝘩𝘢𝘵 𝘢𝘳𝘦 𝘪𝘯 𝘦𝘢𝘳𝘵𝘩, 𝘷𝘪𝘴𝘪𝘣𝘭𝘦 𝘢𝘯𝘥 𝘪𝘯𝘷𝘪𝘴𝘪𝘣𝘭𝘦, 𝘸𝘩𝘦𝘵𝘩𝘦𝘳 𝘵𝘩𝘳𝘰𝘯𝘦𝘴, 𝘰𝘳 𝘥𝘰𝘮𝘪𝘯𝘪𝘰𝘯𝘴, 𝘰𝘳 𝘱𝘳𝘪𝘯𝘤𝘪𝘱𝘢𝘭𝘪𝘵𝘪𝘦𝘴, 𝘰𝘳 𝘱𝘰𝘸𝘦𝘳𝘴: 𝘢𝘭𝘭 𝘵𝘩𝘪𝘯𝘨𝘴 𝘸𝘦𝘳𝘦 𝘤𝘳𝘦𝘢𝘵𝘦𝘥 𝘣𝘺 𝘩𝘪𝘮, 𝘢𝘯𝘥 𝘧𝘰𝘳 𝘩𝘪𝘮.”
They are angels who have direct access to God’s throne in heaven, that is the thrones angels, the cherubim, and seraphim, exude light so bright that it’s compared to fire or gemstones that reflect the light of God’s glory in his dwelling place. The lower Choir of Angels need the Thrones to access God.
Dominions are Angels of Leadership. Members of the dominion angelic choir regulate the other angels and supervise how they perform their God-given duties.
Dominions also often act as channels of mercy for God’s love to flow from him to others in the universe.
Virtues work to encourage human beings to strengthen their faith in God, such as by inspiring people and helping them grow in holiness. They often visit Earth to perform miracles that God has empowered them to perform in response to people’s prayers. Virtues also watch over the natural world God has created on Earth.
Members of the powers choir engage in spiritual warfare against demons. The Powers confront and fight against any evil forces opposed to God’s providential plan. Again, reference is made to these choirs in Colossians 1:16:
𝘍𝘰𝘳 𝘪𝘯 𝘩𝘪𝘮 𝘸𝘦𝘳𝘦 𝘤𝘳𝘦𝘢𝘵𝘦𝘥 𝘢𝘭𝘭 𝘵𝘩𝘪𝘯𝘨𝘴 𝘪𝘯 𝘩𝘦𝘢𝘷𝘦𝘯 𝘢𝘯𝘥 𝘰𝘯 𝘦𝘢𝘳𝘵𝘩: 𝘦𝘷𝘦𝘳𝘺𝘵𝘩𝘪𝘯𝘨 𝘷𝘪𝘴𝘪𝘣𝘭𝘦 𝘢𝘯𝘥 𝘦𝘷𝘦𝘳𝘺𝘵𝘩𝘪𝘯𝘨 𝘪𝘯𝘷𝘪𝘴𝘪𝘣𝘭𝘦, 𝘵𝘩𝘳𝘰𝘯𝘦𝘴, 𝘳𝘶𝘭𝘪𝘯𝘨 𝘧𝘰𝘳𝘤𝘦𝘴, 𝘴𝘰𝘷𝘦𝘳𝘦𝘪𝘨𝘯𝘵𝘪𝘦𝘴, 𝘱𝘰𝘸𝘦𝘳𝘴 — 𝘢𝘭𝘭 𝘵𝘩𝘪𝘯𝘨𝘴 𝘸𝘦𝘳𝘦 𝘤𝘳𝘦𝘢𝘵𝘦𝘥 𝘵𝘩𝘳𝘰𝘶𝘨𝘩 𝘩𝘪𝘮 𝘢𝘯𝘥 𝘧𝘰𝘳 𝘩𝘪𝘮.
They also help human beings overcome the temptation to sin by giving them the courage they need to choose good over evil.
The principality angels encourage people to pray and practice spiritual disciplines that will help them grow closer to God. They work to educate people in the arts and sciences, communicating inspiring ideas in response to people’s prayers. Principalities also oversee the various nations on Earth and help deliver wisdom to national leaders as they face decisions about how best to govern people.
