17, 18. Do not ye yet understand that whatsoever entereth in at the mouth, &c.—Familiar though these sayings have now become, what freedom from bondage to outward things do they proclaim, on the one hand; and on the other, how searching is the truth which they express—that nothing which enters from without can really defile us; and that only the evil that is in the heart, that is allowed to stir there, to rise up in thought and affection, and to flow forth in voluntary action, really defiles a man!

     13. The argument drawn from the indifference of meats (1Co 8:8; Ro 14:14, 17; compare Mr 7:18; Col 2:20-22) to that of fornication does not hold good. Meats doubtless are indifferent, since both they and the "belly" for which they are created are to be "destroyed" in the future state. But "the body is not (created) for fornication, but for the Lord; and the Lord for the body" (as its Redeemer, who hath Himself assumed the body): "And God hath raised up the Lord, and will also raise up us" (that is our bodies): therefore the "body" is not, like the "belly," after having served a temporary use, to be destroyed: Now "he that committeth fornication, sinneth against his own body" (1Co 6:18). Therefore fornication is not indifferent, since it is a sin against one's own body, which, like the Lord for whom it is created, is not to be destroyed, but to be raised to eternal existence. Thus Paul gives here the germ of the three subjects handled in subsequent sections: (1) The relation between the sexes. (2) The question of meats offered to idols. (3) The resurrection of the body.
