The Importance of the Body in Christianity

Christ's Resurrection bestows new dignity on our bodies by revealing to us a new, unexpected, and glorious eternal destiny for them ... "In expectation of that day, the believer's body and soul already participate in the dignity of belonging to Christ" (CCC 1004).

In most religions (such as Hinduism), only spirit is immortal. In some (such as Gnosticism), only spirit is good. In some (such as Buddhism), only spirit is real. But for Christians, the body is real, good, and immortal. No religion exalts matter and the body as Christianity does:

1. God created it and declared it "good" (Gen 1).
2. God united man's body with his immortal soul to make one substance, one being.
3. And therefore he made the body immortal like the soul, through resurrection.
4. In sexual intercourse, he uses a material act to make new immortal souls.
5. And he kept his human body forever. Every since Christ took his human nature, body and soul, to heaven in the Ascension, God has a body forever. Christ did not "un-incarnate" when he ascended.
6. He now uses matter to save souls in Baptism and the Eucharist.

... The practical moral consequences of this doctrine of the resurrection as the body's destiny are radical, especially to contemporary culture. "This dignity entails the demand that he should treat with respect his own body, but also the body of every other person" (CCC 1004). "Do you know that your bodies are the members of Christ? ... Your body is a temple of the Holy Spirit ...You are not your own' you were bought with a price. So glorify God in your body" (1 Cor 6:15, 19-20).

The origin of modern hedonism and materialism (especially the "sexual revolution") is not the discovery of the goodness or greatness of the body, but the denial of it, by the Gnostic separation of body from spirit, by the confinement of religion and morality to subjective intention (the idea that if it is motivated by love, anything is moral). The "materialism" of the playboy really stems from the denial of the sacredness of matter and the body, which is then used as a mere tool, a means to the end of pleasure and excitement. His end is subjectively good feelings in the soul, not the objective good of the body.
