Re: Titus 3:4-11 taking this in pieces (all emphasis mine)
4 but when the goodness and loving kindness of God our Savior appeared, 5 he saved us, not because of deeds done by us in righteousness, but in virtue of his own mercy, by the washing of regeneration and renewal in the Holy Spirit,
“Washing of regeneration” & “renewal in the Holy Spirit” = Baptism
scborromeo.org/ccc/p2s2c1a1.htm#1215 refer to paragraph #1215 inside the link
6 which he poured out upon us richly through Jesus Christ our Savior, 7 so that we might be justified by his grace and become heirs in hope of eternal life.a]
That’s still refering to the effects of baptism. As an aside, “might be justified by his grace and become heirs in hope of eternal life” is said that way because grave (as in mortal) sin can wipe out a person’s salvation.
8 The saying is sure. I desire you to insist on these things, so that those who have believed in God may be careful to apply themselves to good deeds;**(“http://www.biblegateway.com/passage/?search=titus%203&version=RSVCE#fen-RSVCE-34090b”)] these are excellent and profitable to men. 9 But avoid stupid controversies, genealogies, dissensions, and quarrels over the law, for they are unprofitable and futile.
Okay, Paul is talking to those who believe and what Paul insists they should do. But v 10, Paul introduces another person here.
10 As for a man who is factious ( αἱρετικὸν ), after admonishing him once or twice, have nothing more to do with him, 11 knowing that such a person is perverted and sinful; he is self-condemned.
One can’t be a heretic unless they have been baptised. And as you can see, even one who has been baptised can be condemned.
And your point?

The same greek word is used in both readings. It’s διχοστασίαι . The word and understanding is clear.
11 And such were some of you. 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.
see Titus 3:5 above for the answer.
What point are you trying to make with baptism? If one dies in mortal sin, baptism won’t save them.
