Let me just ramble with this:
Go for it.
The remission of our sin in itself, which sin is unrighteousness, would be a moral change, as well as the change of our disposition from enemy of God to son of God.
No actual sanctification implied.
Atonement:
1 Peter 1:2 who have been chosen according to the foreknowledge of God the Father, through the sanctifying work of the Spirit, to be obedient to Jesus Christ and sprinkled with his blood: Grace and peace be yours in abundance.
Hebrews 13:12 And so Jesus also suffered outside the city gate to make the people holy through his own blood[/b].
Hebrews 9:14 How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God!
Hebrews 10:10 And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all.
Washing = cleansing of unrighteousness by the remission of our sin in its atonement.
Washing:
Titus 3:5 he saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit,
1 Corinthians 6:11 And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
Ephesians 5:25-27 Husbands, love your wives, just as Christ loved the church and gave himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless.
Renewal = re-impartation of God's divine eternal life within our immortal human spirit (which Adam lost in the rebellion).
No actual sanctification implied.
Total Depravity to Sanctification:
2 Corinthians 7:1 Therefore, since we have these promises, dear friends,let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God.
Ephesians 4:22 You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires;
Colossians 3:5-9 Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed, which is idolatry. Because of these, the wrath of God is coming. You used to walk in these ways, in the life you once lived. 8 But now you must also rid yourselves of all such things as these: anger, rage, malice, slander, and filthy language from your lips. Do not lie to each other, since you have taken off your old self with its practices
2 Corinthians 5:17 Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!
So, none of the phrases above indicate an actual sanctification at regeneration.
I won't be quick to rule out Titus 3:5, but there is another verse that implies at conversion.
1 Corinthians 1:2 To the church of God in Corinth, to those sanctified in Christ Jesus and called to be his holy people, together with all those everywhere who call on the name of our Lord Jesus Christ—their Lord and ours:
