that each one of you know how to possess himself of his own vessel in sanctification and honor,
      1. It is expressed in these words: That you should abstain from fornication (1 Thessalonians 4:3; 1 Thessalonians 4:3), by which we are to understand all uncleanness whatsoever, either in a married or unmarried state. Adultery is of course included, though fornication is particularly mentioned. And other sorts of uncleanness are also forbidden, of which it is a shame even to speak, though they are done by too many in secret. 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.
