All Commentaries on 1 Thessalonians 4:3 Go To 1 Thessalonians 4
Tertullian of Carthage
AD 220
That we should "abstain from fornication "not from marriage; that every one "should know how to possess his vessel in honour.".
The will of God is our sanctification.
(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."
