In Reformed theology justification is officially distinguished from sanctification. The charge is that Catholicism and the Council of Trent especially confuses these clearly divided steps in the 'Ordo Salutis' (order of salvation - Why are the Reformed using Latin anyway? that's what I want to know). But is this "distinction" biblical? I have had a 42 page email debate with one Presbyterian minister about this before so I don't feel like rehashing it all over again, but I want to just point out one of many examples where St. Paul would be - according the Reformed charge - screwing up the ordo salutis. I'll be using the NRSV.
"Do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived! Fornicators, idolaters, adulterers, male prostitutes, sodomites, 10thieves, the greedy, drunkards, revilers, robbers—none of these will inherit the kingdom of God. 11And this is what some of you used to be. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and in the Spirit of our God." - 1 Corinthians 6:9-11
