that each one of you know how to possess himself of his own vessel in sanctification and honor,

 It may seem strange that Paul should go to such lengths to inculcate sexual purity in a Christian congregation; but two things have to be remembered. First, the Thessalonians had only newly come into the Christian faith and they had come from a society in which chastity was an unknown virtue; they were still in the midst of such a society and the infection of it was playing upon them all the time. It would be exceedingly difficult for them to unlearn what they had for all their lives accepted as natural. Second, there never was an age in history when marriage vows were so disregarded and divorce so disastrously easy. The phrase which we have translated "that each of you should possess his own body in consecration and in honour" could be translated, "that each of you may possess his own wife in consecration and in honour."
