The Parents Summoned: Fear and Evasion
18The Jews therefore didn’t believe concerning him, that he had been blind and had received his sight, until they called the parents of him who had received his sight,19and asked them, “Is this your son, whom you say was born blind? How then does he now see?”20His parents answered them, “We know that this is our son, and that he was born blind;21but how he now sees, we don’t know; or who opened his eyes, we don’t know. He is of age. Ask him. He will speak for himself.”22His parents said these things because they feared the Jews; for the Jews had already agreed that if any man would confess him as Christ, he would be put out of the synagogue.23Therefore his parents said, “He is of age. Ask him.”
Fear of losing your place in the world can silence you even when you've witnessed the miraculous—and the authorities are counting on it.
When the religious authorities refuse to accept the healing of the man born blind, they summon his parents to interrogate them as witnesses. The parents confirm the fact of their son's blindness but, out of fear of excommunication from the synagogue, refuse to testify about how or by whom he was healed. Their evasion contrasts sharply with their son's growing boldness, revealing how the threat of social and religious exclusion can silence even those who know the truth.
Verse 18 — Institutional Disbelief The phrase "the Jews therefore didn't believe" is not a generic ethnic slur but refers specifically to the temple authorities—the Pharisees who function as the interrogating body throughout John 9. Their disbelief is not passive skepticism; it is an active refusal to accept testimony that threatens their theological and institutional control. John characteristically uses the verb episteusan (they believed) in the aorist negative—a completed, decisive rejection. So entrenched is their disbelief that they require the testimony of the man's parents, treating the healing as a legal matter demanding corroboration under a quasi-judicial process. This mirrors the Mosaic requirement of two or three witnesses (Deut 19:15), yet the authorities invoke it not in pursuit of truth but as a strategy of delay and discrediting.
Verse 19 — The Three-Pronged Question The authorities ask three linked questions: Is this your son? Was he born blind? How does he now see? The structure is deliberately lawyerly. The first two questions acknowledge the possibility of a miracle; the third demands an explanation that will either implicate Jesus or expose fraud. The words "whom you say was born blind" carry a subtle accusation—they cast doubt on the parents' own prior testimony, sowing seeds of suspicion. This is the rhetoric of intimidation dressed in procedural language.
Verses 20–21 — The Parents' Partial Testimony The parents are caught in an agonizing bind. They confirm what is certain and public—their son's identity and his congenital blindness—because denial would be absurd and self-incriminating. But they refuse three times to address the healing: "we don't know… we don't know… ask him." The triple repetition is Johannine emphasis. They did not refuse because they were ignorant; the man was an adult living in their household. Their triple "we don't know" is a deliberate act of studied ignorance—they know very well what they don't dare say. St. Augustine (Tractates on John, 44.5) observes that the parents loved their son in the flesh but feared for themselves in the flesh, choosing bodily safety over truthful witness.
Verse 21b — "He Is of Age" The Greek hēlikian echei means literally "he has maturity" or "he has the years." The phrase is a legal and social disclaimer—a parent washing their hands of responsibility for a son's public testimony. In Jewish custom, a man above thirteen bore full legal responsibility. But here the phrase is also ironic in John's theological narrative: the son who was spiritually illumined by Christ is indeed "of age" in a deeper sense—he has received the light and is growing into full witness, while his parents retreat from it.
Catholic tradition reads this passage through the lens of the theology of witness (martyria) and the virtue of fortitude. The Catechism of the Catholic Church teaches that fortitude "ensures firmness in difficulties and constancy in the pursuit of the good" and that it "strengthens the resolve to resist temptations and to overcome obstacles in the moral life" (CCC 1808). The parents of the blind man exhibit the precise failure fortitude is meant to remedy: they capitulate not to violence but to the mere threat of social exclusion. This is the sin of human respect—placing human opinion above divine truth—which the Church has always identified as a grave obstacle to authentic witness.
St. Thomas Aquinas identifies the specific vice at work here as pusillanimity in one dimension and human respect (timor humanus) in another (ST II-II, q. 125, a. 1). The parents are not apostates; they do not deny Christ explicitly. But their calculated silence makes them complicit in the suppression of a miraculous work of God.
The Second Vatican Council's Lumen Gentium (§11) teaches that all the baptized are called to give witness to the faith in their daily lives, particularly within their families and social settings. The parents' failure is thus a failure of the baptismal vocation itself, which demands that every Christian, in the ordinary circumstances of life, be prepared to confess Christ at personal cost.
Pope John Paul II, in Veritatis Splendor (§88–89), insists that martyrdom—the supreme act of witness—is the endpoint of a continuum of testimony that begins in ordinary daily choices about truth and evasion. The parents' evasion is the low end of that continuum; the martyrs of the early Church occupy the high end. Both are measured against the same standard: fidelity to the truth one has received.
The Church Fathers also note the Eucharistic overtone: the man born blind is a type of the catechumen illumined in baptism (Greek: phōtismos, enlightenment, a term for baptism in Justin Martyr and Cyril of Jerusalem), and his parents' refusal to accompany him into full witness suggests those who receive the sacraments but fail to live their transformative demands.
Contemporary Catholics face their own versions of the aposynagōgos threat—not expulsion from synagogues, but professional marginalization, social ridicule, family tension, or cancellation for confessing unpopular truths that flow from Catholic faith. The parents' story is disturbingly contemporary: it is easier to say "I don't know" or "ask someone else" than to risk one's standing in a community by owning what one actually believes.
This passage invites a concrete examination of conscience: Where do I know the truth about Christ—about His Church's teaching on life, marriage, justice, or the sacraments—but deflect, change the subject, or offer studied ambiguity to protect a professional relationship, a family peace, or a social reputation? The parents' three-fold "we don't know" is a mirror for every "it's complicated" or "that's just my private faith" that Catholics deploy when public witness demands a cost.
The antidote the Gospel proposes is not recklessness but the fortitude of the healed man himself—honest, incremental, grounded in personal experience of Christ: "One thing I know: I was blind, and now I see" (v. 25). Catholics are called to speak from that same place of personal encounter, which no authority can argue away.
Verse 22 — The Threat of Aposynagōgos This verse is among the most historically and theologically dense in the Fourth Gospel. John uses the term aposynagōgos—"put out of the synagogue"—which he employs only three times in the Gospel (9:22; 12:42; 16:2). This formal exclusion meant social death in the Jewish world: loss of community, commerce, identity, and worship. Scholars such as J. Louis Martyn have argued that this verse reflects the situation of Johannine Christians facing exclusion from Jewish communities in the late first century, giving the passage a double historical horizon. Yet whatever its compositional history, at the narrative level it reveals the machinery of religious coercion: an a priori agreement (synetetheinto—they had already agreed, a pluperfect of settled policy) to expel anyone who confessed Jesus as Christos. The authorities are not conducting an inquiry; they have pre-decided the verdict.
Verse 23 — Repetition as Condemnation John repeats the parents' deflection word for word: "He is of age. Ask him." The repetition is not literary accident. It is the Evangelist's way of passing moral judgment through narrative form. The parents' words echo hollowly. They have chosen synagogue membership over testimony to the Light of the World. Their silence becomes a structural foil to their son's escalating courage in verses 24–34, where he argues openly, even scornfully, with the Pharisees. The parents who gave him physical sight refuse to stand in the light; the son who received spiritual sight moves ever further into it.
Typological Sense: The parents' fear of the aposynagōgos typifies the broader human temptation to protect one's place within a human institution at the cost of divine truth. In the allegorical reading favored by Origen and Augustine, the man born blind is every soul in the darkness of original sin; his parents represent those who acknowledge faith in part—enough to avoid scandal—but will not proclaim it publicly when it costs something real.
