Question 108. What does the seventh commandment teach us?

Answer: That all uncleanness is accursed of God: (a) and that therefore we must with all our hearts detest the same, (b) and live chastely and temperately, (c) whether in holy wedlock, or in single life. (d)

(a) Lev.18:27 (For all these abominations have the men of the land done, which were before you, and the land is defiled;) Lev.18:28 That the land spue not you out also, when ye defile it, as it spued out the nations that were before you. (b) Jude 1:23 And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh. (c) 1 Thess.4:3 For this is the will of God, even your sanctification, that ye should abstain from fornication: 1 Thess.4:4 That every one of you should know how to possess his vessel in sanctification and honour; 1 Thess.4:5 Not in the lust of concupiscence, even as the Gentiles which know not God: (d) Heb.13:4 Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge. 1 Cor.7:7 For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that. 1 Cor.7:8 I say therefore to the unmarried and widows, It is good for them if they abide even as I. 1 Cor.7:9 But if they cannot contain, let them marry: for it is better to marry than to burn. 1 Cor.7:27 Art thou bound unto a wife? seek not to be loosed. Art thou loosed from a wife? seek not a wife.

Question 109. Does God forbid in this commandment, only adultery, and such like gross sins?

Answer: Since both our body and soul are temples of the holy Ghost, he commands us to preserve them pure and holy: therefore he forbids all unchaste actions, gestures, words, (a) thoughts, desires, (b) and whatever can entice men thereto. (c)

(a) Eph.5:3 But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints; Eph.5:4 Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks. 1 Cor.6:18 Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body. 1 Cor.6:19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? 1 Cor.6:20 For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s. (b) Matt.5:27 Ye have heard that it was said by them of old time, Thou shalt not commit adultery: Matt.5:28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart. (c) Eph.5:18 And be not drunk with wine, wherein is excess; but be filled with the Spirit; 1 Cor.15:33 Be not deceived: evil communications corrupt good manners.
