First-Class, Second-Class and Third-Class Relics

Devotions

The Church’s precise classification of relics — the saint’s body, something the saint owned or used, and something touched to a relic — and the canon law governing their authentication and sale.

The Catholic Church classifies relics into three degrees: a first-class relic is a part of a saint’s body or, for Christ himself, an object connected to his Passion; a second-class relic is something the saint personally owned, wore or used during life; and a third-class relic is any object that has been touched to a first-class or, less commonly, second-class relic. This page focuses specifically on that classification system and the canon law governing authentication and the prohibition on selling relics; the broader theology and history of relic veneration is covered on the companion page <a href=’/devotions/veneration-of-relics/’>Veneration of Relics</a>.

What Is This Devotion?

This page sets out the Church’s precise vocabulary for classifying relics, a topic the companion page on relic veneration touches only briefly. A first-class relic is either a part of a saint’s body — bone, hair or the like — or, in the case of Christ, an object connected directly to his Passion, such as a piece of the True Cross. A second-class relic is something the saint personally used, wore or owned during life, such as a piece of clothing, a rosary, or a book the saint handled; second-class relics are sometimes further described informally as more or less significant depending on how closely tied the object was to the saint’s daily life. A third-class relic is any small piece of cloth or other material that has been touched to a first-class relic, a practice that allows the devotion connected to a major relic to be shared far beyond the single original object.

Origin and History

Formal degrees of relics developed gradually as the Church’s practice of venerating saints’ remains and possessions grew from the early centuries of Christianity. The custom of touching cloth to a saint’s tomb or relic to create what became known as a third-class relic (a brandeum) is documented from the early medieval period as a way to extend devotion to a saint’s holiness without disturbing or dividing the primary relic itself. Over time, dioceses and religious orders developed formal processes for authenticating relics, typically involving a wax seal and an accompanying document, called a theca or authentic, issued by a bishop or his delegate, a system aimed at guarding against the fraud and uncontrolled trade in relics that had periodically troubled the Church, particularly in the medieval period.

Catholic Theology

Relics are venerated, not worshipped, because the saint’s body was the temple of the Holy Spirit in life and awaits the resurrection of the body; the honor shown to a relic passes through it to the saint, and ultimately to God, never terminating in the physical object as though it had independent power (SRC-01; SRC-02). The three-class system exists to keep this veneration honest and well-ordered: it helps the faithful understand exactly what kind of physical connection a given relic has to the saint, rather than treating every object loosely associated with a holy person as equally significant.

How to Practice It

  • Only accept or display a relic that carries proper documentation of authenticity from a competent ecclesiastical authority.
  • Treat a first-class relic with the greatest reverence, typically kept in a proper reliquary and displayed for veneration under a priest’s or the parish’s care rather than treated as a casual personal possession.
  • Understand that owning even a genuine relic never guarantees any particular favor or protection; veneration works through prayer and faith, not through mere physical possession.
  • Never buy or sell a relic; if you are given one, it should have come as a gift, an inheritance, or through an approved ecclesiastical channel.

Associated Prayers

When It’s Observed

There is no feast day attached to the relic classification system itself; individual relics are typically venerated on the feast day of the saint to whom they belong, or on the anniversary of a relic’s translation to a particular church.

Church Status

The classification of relics and the process for their authentication belong to the Church’s canonical discipline on sacred objects. The Code of Canon Law places relics among the sacred objects subject to the Church’s oversight, and current Vatican norms require an accompanying authentication document from a competent ecclesiastical authority before a relic is considered properly verified for veneration; a relic without such documentation, however old or however it is claimed, cannot be presumed authentic (SRC-12).

Promises and Indulgences

The Church attaches no automatic promise or guaranteed grace to possessing any class of relic; whatever spiritual fruit comes from venerating a relic flows from the prayer and faith of the one venerating it, not from the object itself. Canon law is explicit on one closely related point: it is absolutely forbidden to sell sacred relics, and relics of great significance may not be permanently transferred or alienated without the permission of the Apostolic See (canon 1190, SRC-12). A Catholic offered a relic for purchase, whatever the seller’s claims about its origin, should treat that offer itself as a serious warning sign.

Common Misconceptions

“You can buy an authentic relic online or from a private seller.”

You cannot buy a genuine relic at all; canon law absolutely forbids the sale of sacred relics. An item offered for sale as a relic, however convincing the paperwork looks, should be treated with serious suspicion, and reputable religious goods retailers sell only reliquaries, cases and related items, never the relics themselves.

“A third-class relic is not a ‘real’ relic, just a souvenir.”

A properly made and documented third-class relic, a piece of cloth genuinely touched to a first-class relic, is a real relic in the Church’s own classification, even though it carries a less direct physical connection to the saint than a first- or second-class relic does.

Frequently Asked Questions

What is the difference between a first-class and second-class relic?

A first-class relic is part of the saint’s own body, or, for Christ, an object connected to his Passion; a second-class relic is an object the saint personally owned, wore or used during life, such as clothing or a personal item, rather than part of the body itself.

How is a relic authenticated?

A properly authenticated relic is accompanied by a document, sometimes called a theca or authentic, issued and sealed by a bishop or his delegate, certifying the relic’s identity and origin; a relic without this documentation cannot be considered verified.

Can I own a relic in my home?

Yes, ordinary Catholics may own and keep relics, most commonly third-class relics, provided they came through a legitimate, non-commercial channel and are treated with appropriate reverence rather than as curiosities.

Why is it forbidden to sell relics?

Canon law forbids the sale of sacred relics because a relic is not ordinary property to be bought and sold like merchandise; treating it as a commodity would contradict the reverence owed to the saint’s body and the Church’s exercise of oversight over sacred objects.

Is it true that some relics, like fragments of the True Cross, seem to exist in many places at once?

Many small third-class-style fragments and pious traditions have grown up around famous first-class relics over the centuries, and not every historical claim has been rigorously verified; the Church’s current authentication norms exist precisely to bring greater rigor to such claims going forward, rather than to certify every relic tradition inherited from past centuries.

Can a relic be placed inside an altar?

Yes; canon law and liturgical tradition provide for relics, especially of martyrs, to be placed beneath or within a fixed altar, a practice tied to the ancient custom of celebrating the Eucharist over the tombs of martyrs.
