1 Thessalonians 4:3

What, in short, does he write to the Thessalonians withal? "For our consolation (originated) not of seduction, nor of impurity: "and, "This is the will of God, your sanctification, that ye abstain from fornication; that each one know how to possess his vessel in sanctification and honour, not in the lust of concupiscence, as (do) the nations which are ignorant of God." What do the Galatians read? "Manifest are the works of the flesh.

The cardinal principles of chastity, brothers, are ancient. How so? Because they were ordained at the same time as the human race itself. For both her own husband belongs to the woman, for the reason that she may know no other besides him, and because …

Christ gave this judgment when, being inquired of, He said that a wife must not be put away, save for the cause of adultery; such honour did He put upon chastity. Hence arose the decree: "Ye shall not suffer adulteresses to live." Hence the apostle says: "This is the will of God, that ye abstain from fornication." Hence also he says the same thing: "That the members of Christ must not be joined with the members of an harlot." Hence the man is delivered over unto Satan for the destruction of the flesh, who, treading under foot the law of chastity, practises the vices of the flesh. Hence with reason adulterers do not attain the kingdom of heaven. Hence it is that every sin is without the body, but that the adulterer alone sins against his own body. Hence other authoritative utterances of the instructor, all of which it is not necessary at this time to collect, especially among you, who for the most part know and do them; and you cannot find cause for complaint concerning these things, even though they are not described. For the adulterer has not an excuse, nor could he have, because he might take a wife.

"For this is the will of God, even your sanctification." And observe how he nowhere so vehemently glances at any other thing, as at this. As elsewhere also he writes to this effect; "Follow after peace with all men, and the sanctification without which no man shall see the Lord." (Heb. xii. 14) And why dost thou wonder, if he everywhere writes to his disciples upon this subject, when even in his Epistle to Timothy he has said, "Keep thyself pure." (1 Tim. v. 22) Also in his second Epistle to the Corinthians he has said, "In much patience, in fastings, by pureness." (2 Cor. vi. 5, 6) And one may find this in many places, both in this Epistle to the Romans, and everywhere, and in all his Epistles. For in truth this is an evil pernicious to all. And as a swine full charged with mire, wherever he enters, fills all places with his ill odor, and chokes the senses with dung, so too does fornication; it is an evil not easy to be washed away. But when some even who have wives practice this, how excessive is the outrage! "For this," he says, "is the will of God, even your sanctification, that ye abstain from all fornication." For there are many forms of disorderly conduct. The pleasures of wantonness are of many kinds and various, it were not tolerable to mention them. But having said "from all fornication," he leaves it to those who know them.

Providence being a disciplinary art; in the case of others for each individual's sins, and in the case of the Lord and His apostles for ours. To this point says the divine apostle: "For this is the will of God, even your sanctification, that ye abstain from fornication: that each one of you should know how to possess his vessel in sanctification and honour; not in the lust of concupiscence, as the Gentiles who know not the Lord: that none of you should overreach or take advantage of his brother in any matter; because the Lord is the avenger in respect of all such, as we also told you before, and testified. For God hath not called us unto uncleanness, but to holiness. Wherefore he that despiseth, despiseth not man, but God, who hath also given His Holy Spirit to you."

That is, chastity. Everywhere he gives commandment concerning this virtue, both in the Epistle to Timothy (1 Tim. 5:22), and to the Corinthians (1 Cor. 6:6), and to the Hebrews (Heb. 12:14). For this passion is especially strong and therefore requires many and constant remedies. …

It is said through the voice of the prophet to the soul that grows proud, "You trusted in your beauty and played the harlot because of your renown." For a soul to trust in its beauty is to presume within itself on its righteous works. It plays the harlot on the basis of its renown when in its righteous acts it seeks the glory of its own reputation rather than the spread of its Creator's praise.… What then is to be done in this case but that, when the malignant spirit of pride enjoys the good things that we have done in order to exalt the mind, we should ever recall to memory our evil deeds. The goal is that we may acknowledge our sinful acts as our own and our avoidance of sin as the gift of Almighty God. And so Paul says, "For this is the will of God, even your sanctification, that you abstain from unchastity."

The precepts are as follows: this is the will of God, your sanctification, as if saying: All the commandments of God are for the purpose of making you holy; for sanctity means purity and constancy, and all of God's precepts lead thereto, so that a …

Sanctification - Entire holiness of heart and life: particular branches of it are subjoined. That ye abstain from fornication - A beautiful transition from sanctification to a single branch of the contrary; and this shows that nothing is so seemingly distant, or below our thoughts, but we have need to guard against it.

It is the will of God in general that we should be holy, because he that called us is holy, and because we are chosen unto salvation through the sanctification of the Spirit; and not only does God require holiness in the heart, but also purity in our bodies, and that we should cleanse ourselves from all filthiness both of flesh and spirit, 2 Cor. vii.

All that is contrary to chastity in heart, speech, and behaviour, is contrary to the command of God in the decalogue, and contrary to that holiness which the gospel requires. There are several arguments to enforce this caution. As, (1.) This branch of sanctification in particular is the will of God,

For this is the will of God, even your sanctification - It is the will or command of God that you should be holy. This does not refer to the purpose or decree of God, and does not mean that he intended to make them holy - but it means that it was his command that they should be holy. It was also true that it was agreeable to the divine will or purpose that they should be holy, and that he meant to use such an influence as to secure this; but this is not the truth taught here.

For--enforcing the assertion that his "commandments" were "by (the authority of) the Lord Jesus" (1Th 4:2). Since "this is the will of God," let it be your will also. fornication--not regarded as a sin at all among the heathen, and so needing the more to be denounced (Ac 15:20).

This is the will of God, even your sanctification - God has called you to holiness; he requires that you should be holy; for without holiness none can see the Lord. This is the general calling, but in it many particulars are included. Some of these he proceeds to mention; and it is very likely that these had been points on which he gave them particular instructions while among them. That ye should abstain from fornication - The word πορνεια, as we have seen in other places, includes all sorts of uncleanness; and it was probably this consideration that induced several MSS., some versions and fathers, to add here πασης, all. Directions of this kind were peculiarly necessary among the Greeks, and indeed heathens in general, who were strongly addicted to such vices.
