relics. In Christian usage the word is most commonly applied to the material remains of a saint after his death and to sacred objects which have been in contact with his body. The most important relic, however, has been the True Cross (or fragments of it), according to tradition discovered by St
Helena in 326. From an early date the bodies of
martyrs were venerated; clear evidence comes from the ‘Martyrdom of Polycarp’ (
c.156–7). At Rome the cult was linked with the
catacombs, where services were held at their tombs. In opposition to the
Iconoclasts, who rejected the veneration of relics as well as of
icons, the Second Council of
Nicaea (787) anathematized those who despised relics and ordered that no church should be consecrated without them. In the W. the cult increased enormously during the
Crusades, when quantities of relics, often spurious, were brought back from the Holy Land. They were kept in
reliquaries, carried in procession, and often gave rise to superstitious practices.
The theological foundation for the cult of relics was developed in the Middle Ages. Stress was laid on the special dignity of the bodies of saints as temples of the Holy Spirit destined to a glorious resurrection, and on the sanction given by the Godhead in making them the occasion of miracles. The doctrine was confirmed by the Council of
Trent against the Reformers. See also
