Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Spirit;
All Commentaries on Titus 3:5 Go To Titus 3
Augustine of Hippo
AD 430
For if anyone should ask of me whether we have been saved by baptism, I shall not be able to deny it, since the apostle says, “He saved us by the washing of regeneration and renewing of the Holy Spirit.” But if he should ask whether by the same washing he has already in every way immediately saved us, I shall answer: It is not so. Because the same apostle also says, “For we are saved by hope.” .
