He Described 'Born Again' Only to One Person
The phrase 'born again' appears in Jesus's speech exactly once — in a single nighttime conversation with a single Pharisee.
The phrase 'born again' (or 'born anew') is among the most culturally embedded expressions in Christianity, yet in the four gospels it appears in Jesus's direct speech only in John 3, in conversation with Nicodemus alone. Jesus uses the construction twice within that exchange: 'Except a man be born again, he cannot see the kingdom of God' (John 3:3), and then again, 'Marvel not that I said unto thee, Ye must be born again' (John 3:7). Nowhere else in Matthew, Mark, Luke, or John does Jesus use this phrase or return to it — not in public teaching, not in synagogue discourse, not in the farewell discourses, not in post-resurrection speech. The structural oddity is significant: the two uses occur not in a public sermon where mass application would be natural, but in a private, nocturnal dialogue with a named individual, a ruler of the Pharisees. Jesus does not repeat 'born again' to the crowds, to his disciples, or to anyone else across 89 chapters of gospel speech. The phrase is exclusive not just in meaning but in addressee: it is spoken to Nicodemus, singular. The Greek anothen (ἄνωθεν) carries the double meaning 'again' and 'from above,' making the phrase already semantically dense — yet Jesus uses it only here, and Nicodemus's response shows he heard only one meaning, prompting Jesus to expand rather than repeat.

Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
Marvel not that I said unto thee, Ye must be born again.
Evidence Notes
The phrase 'born again' in red-letter text appears only in John 3:3 and 3:7. A full search of red-letter speech in Matthew, Mark, Luke, and John finds no other occurrence of 'born again,' 'born anew,' or the Greek anothen in this regeneration sense in Jesus's direct speech.
Greek Note
The Greek anothen (ἄνωθεν) means both 'again' (temporal) and 'from above' (spatial/divine). Nicodemus hears only the temporal sense, asking how a man can re-enter the womb (John 3:4), prompting Jesus to clarify with 'born of water and of the Spirit' (John 3:5). The ambiguity is embedded in Jesus's word choice itself.
