Porneia denotes sexual wrongdoing, named as conduct to flee, abstain from, repent of, or exclude from a community.

The term consistently names sexual wrongdoing: conduct to be fled, abstained from, put away, or repented of, and conduct listed among other evils. It also occurs in marriage-related exception clauses and in Revelation’s descriptions of Babylon and a woman whose conduct affects nations and kings.

   Across its singular and plural noun forms, the term identifies conduct treated as evil or forbidden. In 1 Corinthians 6:18 the APB renders the command “Flee sexual sin,” while 1 Thessalonians 4:3 says to abstain; in Mark 7:21 and Matthew 15:19 the plural form appears among evils that come from within the heart. In Revelation 2:21 and Revelation 9:21, it is conduct from which people are called to repent.
