>>God has bound salvation to the sacrament of Baptism<<
That is a misinterpretation of Scripture. The paragraph includes the statement “reborn of water and the Spirit”. The verse that comes from is John 3:5 (and it doesn’t say reborn but born)
5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
That refers back to Ezek 36
Ezek 36: 25 Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you.
He was not talking here about physical water but the cleansing of his word. He also calls His word “living water”.
God made this promise to Israel about a new covenant. He said, “Then I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your filthiness and from all you idols. Moreover, I will give you a new heart and put a new spirit within you; I will remove the heart of stone from your flesh and give you a heart of flesh. I will put my Spirit within you and cause you to walk in my statutes, and you will be careful to observe my ordinances or my commandments.”
Now what Ezekiel is writing there is, that the day is going to come when the Lord will wash your heart, he’ll wash your life; he’ll wash your inner man. He’ll put a new heart in you and he’ll put his Spirit in you.
So when Jesus talks to Nicodemus and says, “you must be born of the water and the Spirit,” Nicodemus knows immediately that he is saying, “I am come to bring the fulfillment of the promised new covenant, promised to and through Ezekiel.” Okay? See his is a Jewish Old Testament context, and so it would be actually what the apostle Paul calls, “The washing of regeneration.” The washing, the internal washing of regeneration, and the renewing that comes by the Holy Spirit, that’s Titus 3:5 where you have both the water and the Spirit.
The whole phrase “born of water” is only referring to “born of Jesus word” not physical baptism.
Do you have this verse in your Bible?
1 Peter 3:20 who had once been disobedient while God patiently waited in the days of Noah during the building of the ark, in which a few persons, eight in all, were saved through water.
21 This prefigured baptism, which saves you now. It is not a removal of dirt from the body but an appeal to God 7 for a clear conscience, through the resurrection of Jesus Christ,
22 who has gone into heaven and is at the right hand of God, with angels, authorities, and powers subject to him.
