1 Corinthians 6:12

All things are lawful] cp. 1 Corinthians 10:23. St. Paul seems to have stated this as a principle in regard to the use of certain kinds of food (e.g. meats offered to idols, 1 Corinthians 10:25; 1 Corinthians 10:27), and the Corinthians had applied it generally to sensual indulgences. The Apostles, therefore, while still asserting the principle, points out two qualifications of it; (a) that what is lawful should also be beneficial, and (b) that no one should become a slave even to a lawful habit. We shall best understand the principle and its application if we think of it in relation to some such modern practice as, e.g., the use of strong drink.
