Well the entire John 3 conversation is supports my understanding but I was starting with just the next verse.
What is an ECCF?
Early Catholic Church fathers
Vs 22 don’t it says baptism
Jn 1,2,3,4 baptismal regeneration
John1:26 John answered them, saying, I baptize with water: but there standeth one among you, whom ye know not; (John prepared the way by baptism)
John 2:6 And there were set there six waterpots of stone, after the manner of the purifying of the Jews, containing two or three firkins apiece. (Old covenant prefiguring of baptism, purification from sin)(His disciples believed because the ever Virgin mother of God interceded Jn 2:11)
John3:5 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. (Baptism)
(Key verse! Actions speak louder than words: verse 22)
John 3:22 After these things came Jesus and his disciples into the land of Judaea; and there he tarried with them, and baptized. 23 And John also was baptizing in Aenon near to Salim, because there was much water there: and they came, and were baptized.(Baptism / water)
John 4:1 When therefore the Lord knew how the Pharisees had heard that Jesus made and baptized more disciples than John.
Born again means Baptismal regeneration!
Thanks
