Not by works of righteousness. — This by no means asserts that such works ever had been done, and then produced, as it were, before the bar of God, and weighed and found insufficient; but it simply maintains that to win salvation such must be done. Sad experience, more forcibly than any theological assertion, has demonstrated to us all the utter impossibility of any of us, even the holiest, ever, even for one day, doing the works of a purely righteous man.
But according to his mercy. — As there was nothing in us which called for such a salvation, as there were no acts of ours which deserved reward, His gift of salvation, which includes (Titus 3:7) eternal life, was owing entirely to His divine love which saw and pitied our misery, our endless suffering. Out of this hopeless state the eternal pity lifted us, and put us into a state of salvation. The next clause specifies the outward and visible sign of the salvation our loving God was pleased to ordain in His Church, namely, “baptism;” but here great care must be taken properly to understand what St. Paul meant by this baptism, to which he attributed so great power. In St. Paul’s mind it was no mere observance, but was a sacrament, in which all that was inward properly and completely accompanied all that was outward. In another place the Apostle has grandly paraphrased his words here. In the Galatian Letter (Galatians 3:27) he writes how “that as many as were baptised into Christ have put on Christ,” that is, have entered into vital union with Him — a blessed state, which most surely leads to life eternal, if the baptised only remain faithful.
By the washing of regeneration, and renewing of the Holy Ghost. — Seeing, then, that God has saved us by His own act, independently of any work of ours, we ask, How has He effected this? The words we are here considering give the answer to the question. The Greek should be rendered, “by the laver of regeneration,” &c. Then, by means of the laver of regeneration, &c, has God put us into a state of salvation. In other words, He has effected this by means of “baptism” (for the laver here can only signify the baptismal font, and is called the laver of regeneration because it is the vessel consecrated to the use of that sacrament), whereby, in its completeness as a sacrament, the new life in Christ is conveyed. Baptism, then, is the means through which we receive the saving grace of Christ; in its laver we are born again to a new life, in it we receive strength through the Holy Ghost constantly to renew and to develop this new life, for it is not only the laver of regeneration but also of renovation by the Holy Spirit. But baptism is here understood in all its completion — the outward visible sign accompanied with the inward spiritual grace. In the case of one who is come to years of understanding seeking baptism, repentance and faith in the promises of God are absolutely required. In the case of infants, who have also from the very earliest times been, through this same laver, enrolled in the communion of Christians, the same profession is required, only they make it by their sureties, and directly that they have come to years of discretion they solemnly and publicly assent to what had been already affirmed in their name. Thus, by means of the laver of regeneration, &c, or, in other words, by baptism in all its completion — the outward act being accompanied with the inward faith — He saved us, that is, put us into a state of salvation. Of the difference between “regeneration” and “renovation,” the first, “regeneration,” is well explained in the words of the collect for Christmas Day, which speaks of the “regenerated” as “made God’s children by adoption and grace.” The second, “renovation,” the same collect goes on to speak of, when it prays that “the regenerated” “may daily be renewed by the Holy Spirit.” The first, “regeneration,” is spoken of by St. John in his words, “Ye must be born again” (John 3:7); the second is alluded to by St. Paul when he wrote, “the inward man is renewed day by day” (2 Corinthians 4:16).
