Body-soul unity is the doctrine that man is a single, integrated whole—an embodied soul and an ensouled body—and not a soul merely housed in or imprisoned by a body, nor a body that happens to produce a soul. When God formed the body from the dust and breathed into it the breath of life, the result was not a soul wearing a body but a living person, a unity in which the material and immaterial are intimately joined and meant to be together. Scripture everywhere treats man as such a unity: he sins, worships, loves, and serves God with his whole self, body and soul; the body is not a contemptible shell but a member of the person, the temple of the Holy Ghost in the believer, to be presented as a living sacrifice and kept holy. This unity has profound implications. It dignifies the body as God’s good creation, against the Greek and Gnostic contempt that despised matter and longed to escape the flesh; the body is to be honored, disciplined, and one day redeemed, not abandoned. It explains why death—the rending of body and soul—is unnatural and dreadful, an enemy and a violence done to the integrity of the person, not a welcome liberation of the soul. And it grounds the hope of the resurrection: the believer’s redemption is not complete at death, when the soul goes to be with Christ, for the body still lies in the grave; the person is not whole again until soul and body are reunited in the resurrection, when the redeemed shall be glorified in body as well as soul. Body-soul unity thus stands against both the materialism that denies the soul and the spiritualism that despises the body, confessing that God made man a unity, that He redeems the whole man, and that He will raise the body to be reunited with the soul in everlasting life.
