Irenaeus, on 1Cor 3:16

“Know you not, that you are the temple of God, and that the Spirit of God dwelleth in you?”

“Whence also he says, that this handiwork is "the temple of God," thus declaring: "Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? If any man, therefore, will defile the temple of God, him will God destroy: for the temple of God is holy, which [temple] ye are." Here he manifestly declares the body to be the temple in which the Spirit dwells. As also the Lord speaks in reference to Himself, "Destroy this temple, and in three days I will raise it up. He spake this, however," it is said, "of the temple of His body."”
