All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any.
All Commentaries on 1 Corinthians 6:12 Go To 1 Corinthians 6
John Chrysostom
AD 407
Paul means that if we are free to choose, then we should remain free and not become a slave to any particular desire. Anyone who orders his desires properly remains the master of them, but once he goes beyond this limit he loses control and becomes their slave.
