Flee fornication. Every sin that a man does is outside the body; but he that commits fornication sins against his own body.
All Commentaries on 1 Corinthians 6:18 Go To 1 Corinthians 6
Ambrosiaster
AD 400
If someone hangs himself or kills himself with a dagger, he does not sin against his body but against his soul, on which he inflicts violence. But to fornicate is a sin of the body which touches both the body and the soul. Commentary on Paul’s Epistles.
