Second Interrogation: The Healed Man's Bold Testimony (Part 1)
24So they called the man who was blind a second time, and said to him, “Give glory to God. We know that this man is a sinner.”25He therefore answered, “I don’t know if he is a sinner. One thing I do know: that though I was blind, now I see.”26They said to him again, “What did he do to you? How did he open your eyes?”27He answered them, “I told you already, and you didn’t listen. Why do you want to hear it again? You don’t also want to become his disciples, do you?”28They insulted him and said, “You are his disciple, but we are disciples of Moses.29We know that God has spoken to Moses. But as for this man, we don’t know where he comes from.”30The man answered them, “How amazing! You don’t know where he comes from, yet he opened my eyes.31We know that God doesn’t listen to sinners, but if anyone is a worshiper of God and does his will, he listens to him.
John 9:24–31 depicts a confrontation between Pharisaic authorities and a formerly blind man they healed by Jesus, who refuse to validate his testimony and demand he denounce his healer. The man resists their coercive interrogation by affirming the undeniable fact of his healing and turning their own theological logic against them to argue that Jesus must be from God.
A man with nothing but his own experience outargues the theologians—because transformed lives are the argument religion cannot counter.
Commentary
John 9:24 — "Give glory to God. We know that this man is a sinner." The Pharisees' command to "give glory to God" is a solemn judicial formula found in Joshua 7:19, where Achan is urged to confess his sin before execution. It carries the force of a sworn oath and an implicit demand that the man recant his positive account of Jesus. The phrase is not an invitation to worship but a legal pressure tactic: acknowledge the truth (as we define it) or be held in contempt of God. Their declaration "we know that this man is a sinner" is stated with the same confident plural ("we know") they will use again in John 9:29 — revealing that their "knowledge" is ideological certainty, not inquiry. The irony John cultivates is exquisite: those who claim to know are blind; the one who was blind is coming to see.
John 9:25 — "I don't know if he is a sinner. One thing I do know…" The healed man's reply is a masterpiece of honest epistemology. He does not claim more than he can verify, conceding uncertainty about the theological classification of Jesus. But he plants his feet on what no argument can dislodge: the fact of his own transformation. "Though I was blind, now I see" (τυφλὸς ὢν ἄρτι βλέπω) is stated with perfect simplicity, in the present tense — the seeing is ongoing, the change is permanent. Augustine famously meditated on this verse: the man cannot answer the philosophical question, but the miracle answers for him. He is not a theologian; he is a witness. This models the patristic distinction between scientia (theoretical knowledge) and sapientia (wisdom born of experience of God).
John 9:26 — "What did he do to you? How did he open your eyes?" The Pharisees circle back, hoping for an inconsistency or an admission they can use. The repetition of the question exposes their bad faith — they are not seeking understanding; they are seeking a pretext. Legally and rhetorically, repeating the same question is a technique of exhaustion. John's narrative pacing here deliberately slows, forcing the reader to feel the harassment of the interrogation.
John 9:27 — "I told you already… You don't also want to become his disciples, do you?" At this point the healed man's patience snaps into irony. His question — "You don't also want to become his disciples, do you?" — is sarcastic in tone (μὴ καὶ ὑμεῖς θέλετε; uses the particle μή, expecting a negative answer), but its content is deeply provocative. He speaks as though he himself is already numbered among Jesus' disciples — "also" (καί) implies you too, like me. This is the first moment in the narrative where the healed man implicitly identifies himself with Jesus' following. His journey from passive recipient of healing to active defender of his healer reaches a new stage.
John 9:28–29 — "You are his disciple, but we are disciples of Moses." The Pharisees' insult and counter-claim reveals what is truly at stake: not the healing, but competing authorities. Moses versus Jesus. They invoke Moses as the validating source of revelation ("God has spoken to Moses") while dismissing Jesus' origin as unknown and therefore suspect. "We don't know where he comes from" is deeply ironic in John's Gospel, where "whence" (πόθεν) is a repeated theological keyword. The reader of the Fourth Gospel knows exactly where Jesus comes from: from the Father (John 1:1–14; 8:42). The Pharisees' ignorance of Jesus' origin is not geographical; it is spiritual blindness.
John 9:30–31 — "How amazing! You don't know where he comes from, yet he opened my eyes." The healed man's rhetorical counterattack is brilliant. He uses the Pharisees' own theological principle — that God does not listen to sinners — to argue for Jesus' divine authorization. His reasoning is syllogistic: (1) God only hears those who worship Him and do His will (a commonplace drawn from Psalm 66:18 and Proverbs 15:29); (2) Jesus performed an unprecedented miracle (restoring sight to one born blind, v.32 — unheard of since the world began); (3) Therefore, God must have heard Jesus; (4) Therefore, Jesus cannot be a sinner outside God's favor. This is a reductio ad absurdum of the Pharisees' position using their own premises. The man who was born blind is now delivering theological argument with more cogency than his interrogators. Sight — literal and spiritual — is spreading within him even as the scene unfolds.
Catholic Commentary
Catholic tradition reads this passage on multiple levels simultaneously, consistent with the four senses of Scripture articulated in Dei Verbum §12 and expounded by the Catechism (CCC 115–119).
Literal/Historical: A legal interrogation in which a miracle-recipient refuses to be silenced, ultimately arguing from experience and Scripture for Jesus' divine authority.
Allegorical: The healed man is a figure of the soul illumined by Baptism. Augustine's Tractates on John (Tract. 44) explicitly connects the man's progressive boldness to the deepening of baptismal grace — just as the newly baptized move from reception of light to active testimony. The washing in the Pool of Siloam (v.7) is already interpreted by Augustine and Cyril of Alexandria as a type of Baptism; the man's growing courage before authorities mirrors the post-baptismal strengthening of Confirmation (CCC 1303).
Moral: The man models the virtue of fortitude in witness — what CCC 2471 calls the "duty" of every Christian to bear witness to the truth even at personal cost. He is insulted (v.28), implicitly threatened with synagogue expulsion (anticipated in v.22), and yet does not flinch.
Anagogical: The exchange prefigures the eschatological reversal: those who see will be made blind; those who were blind will receive eternal sight (John 9:39). The Pharisees' stubborn "knowledge" is a warning against the spiritual pride that forecloses the grace of conversion.
The Catechism's teaching that "faith seeks understanding" (fides quaerens intellectum, CCC 158) is embodied inversely here: the man does not begin with understanding, but from faith born of experience he arrives at a kind of natural theological reasoning that surpasses his formally educated interrogators. Pope Francis in Evangelii Gaudium §265 calls this the "mystical fraternity" of those who, having encountered Christ, cannot be argued out of that encounter.
For Today
Contemporary Catholics face a version of the Pharisees' intimidation whenever they are asked to deny or qualify their experience of Christ in secularized or hostile contexts — in workplaces, universities, or even within Church communities fractured by controversy. The healed man offers a model that is neither intellectually dishonest nor spiritually naive. He says, in effect: I cannot win every theological argument, but I cannot deny what has happened to me. This is the irreducible core of Christian witness — the personal testimony of transformation.
Catholics who feel ill-equipped to debate doctrine should take courage: the healed man wins no formal theological debate, yet his simple, unshakeable testimony is the most powerful argument in the room. Parish communities, RCIA sponsors, and individuals sharing faith in hostile environments should note that verse 25 is not an abdication of reason but a claim about the priority of personal encounter with Christ — entirely consistent with Benedict XVI's teaching in Deus Caritas Est §1: "Being Christian is not the result of an ethical choice or a lofty idea, but the encounter with an event, a person." Do not be ashamed to say: I was blind; now I see.
