1 Corinthians 6:15-18 - Joseph Benson’s Commentary on the Old and New Testaments

Know ye not that your bodies are the members of Christ Mystically united to him, as well as your souls, if you are his true disciples, as you profess to be. Shall I then take the members of Christ My body, which is united to him, with its members; and make them the members of a harlot United to her, and used to gratify her sinful inclinations? Know ye not Need I inform you; that he who is joined to a harlot is one body with her? But he that is joined unto the Lord By faith and love; is one spirit with him. And shall he make himself one flesh with a harlot? Flee fornication All unlawful commerce with women, with speed, with abhorrence, with all your might. Every sin that a man doeth Every other sin, except gluttony and drunkenness, or every other sin that a man commits against his neighbour; is without the body Terminates in an object out of himself, and does not so immediately pollute his body, though it does his soul. But he that committeth fornication Or any kind of lewdness; sinneth against his own body Pollutes, dishonours, and degrades it to a level with brute beasts; and perhaps infects and enfeebles, wastes and consumes it, which these vices have a manifest tendency to do. Inasmuch as the person who is addicted to gluttony and drunkenness sins against his own body, as well as a fornicator, and debilitates it by introducing into it many painful and deadly diseases: in this prohibition of fornication, those vices likewise are comprehended, being indeed the ordinary concomitants of it. And the way to flee whoredom, is to banish out of the mind all lascivious imaginations, and to avoid carefully the objects and occasions of committing that vice, and to maintain habitual temperance in the use of meat and drink.
