The priest's cross depicts the crucified Christ, whether in painted form as an icon, or in relief. However, the Orthodox crucifix differs from the Western type by the fact that the "soma" (body of Christ) is not in full three-dimensional form, but in no more than three-quarter relief. It also bears the inscription INBI (the titulus that Pontius Pilate placed above the head of Jesus at the crucifixion) and the letters IC XC NIKA around the four arms of the cross. Orthodox pectoral crosses are almost always on chains of either silver or gold, sometimes with intricately worked links. Priest's crosses will often have an icon of Christ "Made Without Hands" at the top. This is the icon before which Orthodox Christians usually confess their sins. In Russian practice, the back of a priest's cross is usually inscribed with St. Paul's words to St. Timothy: "Be an example to the believers in speech and conduct, in love, in faith, in purity" (1 Tim. 4:12).
