The Holy Body Is the Temple of the Holy Spirit

Ori, the holy body is the temple. And here he is not primarily talking about whether one should eat that extra piece of meat or have a doughnut. Sexually, to sleep with somebody other than one's spouse is using your body in an inappropriate way. Whatever behavior someone wants to condemn, we need to locate it in the context of the passage itself. It's important to remember that he did just get done calling them washed, sanctified and justified. He is not telling them to reform these behaviours in order to become those things.
