What does it mean to defile the temple of God in 1 Corinthians 3:17?

In 1 Corinthians 3:17, defiling the temple of God refers to defiling one’s physical body, since the temple is the believer. God’s destruction is of that body—the flesh—not the soul and spirit. The example in 1 Corinthians 5:5 delivers the flesh to Satan for destruction, not the soul and spirit.

Les teaches that 1 Corinthians 3:17 says if any man defile the temple of God, him shall God destroy, for the temple of God is holy, and that temple is you. He explains that this defiling refers to the physical body, not the soul and spirit. The body is the third part of us and can be separated from the soul and spirit; when God speaks of destroying the body, the temple, He will not touch the soul and spirit. As an example, Les points to 1 Corinthians 5:4–5, where Paul, gathered with the local church in spirit and with the power of the Lord Jesus Christ, delivers such a one unto Satan for the destruction of the flesh, not the soul and spirit. This illustrates that the destruction concerns the flesh, while the soul and spirit remain untouched.
