But the Jews did not believe concerning him, that he had been blind, and received his sight, until they called the parents of him that had received his sight.
All Commentaries on John 9:18 Go To John 9
John Chrysostom
AD 407
The Pharisees being unable, by intimidation, to deter the blind man from publicly proclaiming his Benefactor, try to nullify the miracle through the parents. But the Jews did not believe concerning him, that he had been blind, and received his sight, until they had called the parents of him that had received his sight.
But it is the nature of truth, to be strengthened by the very snares that are laid against it. A lie is its own antagonist, and by its attempts to injure the truth, sets it off to greater advantage: as is the case now. For the argument which might otherwise have been urged, that the neighbors knew nothing for certain, but spoke from a mere resemblance, is cutoff by introduction of the parents, who could of course testify to their own son. Having brought these before the assembly, they interrogate them with great sharpness, saying, Is this your son, (they say not, who was born blind, but) who you say was born blind? Say. Why what father is there, that would say such things of a son, if they were not true? Why not say atonce, Whom you made blind? They try two ways of making them deny the miracle: by saying, Who you say was born blind, and by adding, How then does he now see?.
Three things then being asked, - if he were their son, if he had been blind, and how he saw, - they acknowledge two of them: his parents answered them and said, We know that this is our son, and that he was born blind. But the third they refuse to speak to: But by what means he now sees, we know not. The inquiry in this way ends in confirming the truth of the miracle, by making it rest upon the incontrovertible evidence of the confession of the healed person himself; He is of age, they say, ask him; he can speak for himself.
What sort of gratitude is this in the parents; concealing what they knew, from fear of the Jews? as we are next told; These words spoke his parents, because they feared the Jews. And then the Evangelist mentions again what the intentions and dispositions of the Jews were: For the Jews had agreed already, that if any man did confess that He was Christ, he should be put out of the synagogue.
