The Bible tells us that when Jesus returns to earth, he will physically raise all those who have died, giving them back the bodies they lost at death. These will be the same bodies people had in earthly life—but our resurrection bodies will not die and, for the righteous, they will be transformed into a glorified state, freed from suffering and pain, and enabled to do many of the amazing things Jesus could do with his glorified body (cf. 1 Cor. 15:35–44, 1 John 3:2). The resurrection of the body is an essential Christian doctrine, as the apostle Paul declares: “[I]f the dead are not raised, then Christ has not been raised. If Christ has not been raised, your faith is futile and you are still in your sins. Then those also who have fallen asleep in Christ have perished” (1 Cor. 15:13–18). Because, as Paul tells us, the Christian faith cannot exist without this doctrine, it has been infallibly defined by the Church. It is included in the three infallible professions of faith—the Apostles’ Creed, the Nicene Creed, and the Athanasian Creed—and has been solemnly, infallibly taught by ecumenical councils. The Fourth Lateran Council (1215), infallibly defined that at the second coming Jesus “will judge the living and the dead, to render to every person according to his works, both to the reprobate and to the elect. All of them will rise with their own bodies, which they now wear, so as to receive according to their deserts, whether these be good or bad [Rom. 2:6–11]” (constitution 1). Most recently, the Catechism of the Catholic Church reiterated this long-defined teaching, stating, “‘We believe in the true resurrection of this flesh that we now possess’ (Council of Lyons II). We sow a corruptible body in the tomb, but he raises up an incorruptible body, a ‘spiritual body’ (cf. 1 Cor 15:42–44)” (CCC 1017).
