Relic

What it is

A relic is a remnant of a saint—or of the Passion of Christ—honored by the Church. Tradition distinguishes classes: first-class (part of the saint's body), second-class (an object the saint used or wore), third-class (an object touched to a first- or second-class relic). The logic is Incarnational: God works through matter; the bodies of the saints were temples of the Holy Spirit.

What it is not

Veneration of relics is not worship of bone and cloth. It is not necromancy. It is not a guarantee of authenticity for every fragment sold online—the Church regulates the authentication and exposure of relics precisely because fraud and superstition are real. A relic is not a SacramentGlossaryOne of seven efficacious signs of grace instituted by Christ: Baptism, Confirmation, Eucharist, Penance, Anointing, Orders, Matrimony..

How a Catholic encounters it

You encounter relics in altar stones (historically), in reliquaries during feast days, at pilgrimage shrines, and sometimes in parish expositions. Kiss or touch a relic with reverence if the custom allows; ask the saint's intercession; give the glory to God. If you own a third-class relic or a blessed medal, treat it as sacred, not as merchandise.
