That no man transgress and wrong his brother in any matter: because the Lord is the avenger of all such, as we also have forewarned you and testified.
All Commentaries on 1 Thessalonians 4:6 Go To 1 Thessalonians 4
John Chrysostom
AD 407
He has well said, that no man transgress. To each man God has assigned a wife, he has set bounds to nature, that intercourse with one only: therefore intercourse with another is transgression, and the taking of more than belongs to one, and robbery; or rather it is more cruel than any robbery; for we grieve not so much, when our riches are carried off, as when marriage is invaded. Do you call him brother, and wrongest him, and that in things which are unlawful? Here he speaks concerning adultery, but above also concerning all fornication. For since he was about to say, That no man transgress and wrong his brother, Do not think, he says, that I say this only in the case of brethren; you must not have the wives of others at all, nor even women that have no husbands, and that are common. You must abstain from all fornication; Because, he says, the Lord is an avenger in all these things. He exhorted them first, he shamed them, saying, even as the Gentiles. Then from reasonings he showed the impropriety of defrauding a brother. Afterwards he adds the principal thing; Because, he says, the Lord is an avenger in all these things, as also we forewarned you and testified. For we do not these things without being punished, neither do we enjoy so much pleasure, as we undergo punishment.
