Jesus answered, "Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.
John derives from Hebrew Yohanan (longer form y'hohanan), said to mean literally "Jehovah has favored".
Could be only a coincidence that just the “born of water” par excellence, John, was the only “favored by YHWH” who could enter the kingdom of God?
In addition to this, it seems that the role of John in the Gospels is to initiate the Jews, by the his secret knowledge, to the secret advent of Jesus.
We have another figure who initiated Valentinus by the secret teachings of Paul:
they say that Valentinus was a hearer of Theudas, and Theudas, in turn, a disciple of Paul.”
(Clement, Strom. VII.17)
The Theudas described in Josephus resembles strictly the John the Baptist figure:
Could the pauline Theudas precursor of Valentinus (a mythical figure) have inspired the creation of an anti-pauline anti-Theudas precursor of the Gospel Jesus (a mythical figure) in the figure of “John the Baptist” ?Now it came to pass, while Fadus was procurator of Judea [44-46], that a certain magician, whose name was Theudas, persuaded a great part of the people to take their effects with them, and follow him to the river Jordan; for he told them he was a prophet, and that he would, by his own command, divide the river, and afford them an easy passage over it; and many were deluded by his words. However, Fadus did not permit them to make any advantage of his wild attempt, but sent a troop of horsemen out against them; who, falling upon them unexpectedly, slew many of them, and took many of them alive. They also took Theudas alive, and cut off his head, and carried it to Jerusalem.
