Devotion to the Nine Choirs of Angels

Devotions

The traditional ninefold ranking of angels, from Seraphim to Angels, systematized by Pseudo-Dionysius the Areopagite and later refined by St. Thomas Aquinas.

Devotion to the Nine Choirs of Angels honors the traditional ninefold ranking of the angelic hosts: Seraphim, Cherubim and Thrones; Dominations, Virtues and Powers; and Principalities, Archangels and Angels. This scheme was systematized around the late fifth or early sixth century by the theologian known as Pseudo-Dionysius the Areopagite and later taken up and refined by St. Thomas Aquinas in the Summa Theologiae. While individual choir names appear in Scripture, the specific ninefold ordering itself is a respected theological tradition rather than a formally defined dogma, and Catholics are not bound to accept every structural detail as revealed truth.

Quick Facts

  • Category: Holy Angels — Angelic Devotions
  • Origin: A ninefold angelic hierarchy systematized by the theologian known as Pseudo-Dionysius the Areopagite, probably writing in the late fifth or early sixth century, and later developed by St. Thomas Aquinas
  • Feast: September 29 (Archangels); October 2 (Guardian Angels), the observances closest to two of the nine choirs
  • Church status: A longstanding and respected theological tradition rather than a dogmatically defined doctrine; Catholics may hold it without being obligated to affirm every structural detail
  • Private revelation: Not dependent on private revelation; the hierarchy is a work of theological synthesis, not a reported vision

What Is This Devotion?

This devotion honors the nine traditional ranks, or “choirs,” into which Catholic theological tradition has long organized the angels, grouped into three triads: Seraphim, Cherubim and Thrones closest to God; Dominations, Virtues and Powers governing the working-out of divine providence; and Principalities, Archangels and Angels most directly engaged with human affairs. Where devotion to the holy angels in general or to one’s own guardian angel is personal and direct, this devotion is more contemplative, inviting reflection on the sheer variety and order Catholic tradition perceives among purely spiritual creatures.

Origin and History

The ninefold scheme comes from a work called the Celestial Hierarchy, written under the name of Dionysius the Areopagite — the Athenian convert of St. Paul mentioned in Acts 17:34 — by an author modern scholars agree was writing centuries later, probably in the late fifth or early sixth century; historians refer to this anonymous author today as Pseudo-Dionysius. Drawing on scattered biblical terms for different kinds of heavenly beings — seraphim in Isaiah 6, cherubim in Genesis and Ezekiel, and thrones, dominions, principalities and powers in Colossians 1 and Ephesians 1 — Pseudo-Dionysius wove them into a single, ordered system that Scripture itself never assembles in one place.

St. Thomas Aquinas received this scheme in the thirteenth century and gave it lasting authority within Catholic theology, largely accepting Pseudo-Dionysius’s ninefold ordering while refining the reasoning behind each rank’s place in his Summa Theologiae (Prima Pars, Question 108). Because this synthesis came from theological reasoning rather than a direct scriptural revelation or a Church council’s formal definition, it holds the weight of a widely respected and long-taught tradition rather than binding dogma.

Catholic Theology

The nine choirs express, in angelic terms, a broader Catholic conviction: that God’s creation is marked by rich order and diversity even among purely spiritual beings, each rank reflecting different ways of knowing and serving God. This mirrors, in its own register, Catholic teaching on the diversity of gifts and vocations among the faithful on earth. The Church commends this tradition as a fruitful aid to prayer and reflection on creation’s order, without requiring precise assent to every detail as an article of faith.

How to Practice It

  • Pray the traditional Prayer to the Nine Choirs of Angels, invoking each rank in turn.
  • Study the biblical passages behind each choir’s name to ground the devotion directly in Scripture.
  • Treat the ninefold ordering as a respected aid to prayer and reflection, not a rigid doctrine requiring precise belief in every structural detail.
  • Pair this devotion with honoring the three named archangels and one’s own guardian angel, the choirs closest to ordinary Catholic life.

Associated Prayers

When It’s Observed

There is no dedicated universal feast for the ninefold hierarchy as such; the observances that touch it most directly are September 29, for the choir of Archangels, and October 2, for Angels understood as guardians.

Church Status

The nine choirs form a centuries-old theological tradition carried by a Doctor of the Church and reflected widely in Catholic art, liturgy and prayer, but the scheme has never been solemnly defined by the Church’s magisterium. Catholics may hold variant views on the precise ordering of the ranks without departing from the faith, so long as they affirm what the Church does teach with certainty: that angels are real, created, spiritual beings who serve God’s plan.

Common Misconceptions

“The ninefold hierarchy of angels is defined Catholic dogma that every Catholic must believe in exact detail.”

It is not. The nine choirs represent a theological tradition of great antiquity and authority, especially through St. Thomas Aquinas’s use of it, but it has never been solemnly defined as dogma by a pope or council. The Church requires belief that angels exist and serve God’s plan; it does not require adherence to every detail of one particular ranking system for organizing them.

Frequently Asked Questions

What are the nine choirs of angels, in order?

In the traditional ordering: Seraphim, Cherubim and Thrones form the first and highest triad; Dominations, Virtues and Powers form the second; and Principalities, Archangels and Angels form the third, closest to human affairs.

Is this hierarchy actually in the Bible?

The individual names are — seraphim appear in Isaiah 6, cherubim in Genesis and Ezekiel, and thrones, dominions, principalities and powers in Colossians 1 and Ephesians 1 — but Scripture never assembles them into one single ordered list of nine. That synthesis came later, from Pseudo-Dionysius the Areopagite.

Did St. Thomas Aquinas invent the nine choirs?

No. He inherited the scheme from Pseudo-Dionysius’s Celestial Hierarchy and refined and defended it in the Summa Theologiae, giving it lasting influence in Catholic theology, but he was not its original author.
