Revivalist Charles Finney refuted the false Calvinistic doctrine of “justification by faith” while living unsanctified in “daily sin.”
You ought to understand, brethren, that the doctrine of justification by faith, as it is now generally held by the orthodox churches, is a modern invention, and was unknown to the ancient church. It is this, that men are justified by faith in Christ, while they are not sanctified. In other words, that faith is so substituted for holiness, that they are accounted as righteous, while in fact they are not so, but are living in the daily and hourly practice of sin.
The doctrine of the primitive Church was, that men are made righteous by faith. In other words, that they are sanctified, or made holy, by faith, and that they were justified only so far as they were made just by the grace of God through faith. Now this must be the truth. And take heed to the doctrine, brethren, that you do not convey the idea, that men are justified while living in sin.
This is what the Bible teaches on justification as well:
“Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.” 1 Corinthians 6:9-11
