John 9:20

Now when there were three questions asked, whether he was their son, whether he had been blind, and how he received his sight, the parents only acknowledged two of them, but do not add the third. And this came to pass for the sake of the truth, in order that none other save the man that was healed, who was also worthy of credit, should acknowledge this matter. And how would the parents have favored Christ, when even of what they knew some part they spake not through fear of the Jews? What say they? "We know that this is our son, and that he was born blind; but by what means he now seeth we know not, or who hath opened his eyes we know not; he is of age, he shall speak for himself." By making him to be worthy of credit, they begged off themselves; "He is not a child, say they, nor incapable, but able to testify for himself."

They acknowledge as true that which was in no wise doubtful and for which it was hardly likely they would suffer anything disagreeable; for they say that they recognise their own offspring, and do not deny what really was the case at his birth, but distinctly affirm that he was born with the affliction. Nevertheless they shrink from relating the miracle, leaving the nature of the deed to speak for itself, and maintaining that it would be much more suitable to put the question as to how he had been healed to their son himself. Fear of danger is certainly a powerful motive to turn men aside from what it befits them to do. Being greatly alarmed by the harshness of the Pharisees, they do not observe that which is somewhere well said: Strive for the truth unto death. It is likely that they did suffer something of another sort; for the poor man is always timid, and, losing through, his poverty the power to offer bold resistance, often takes refuge in an unwilling silence, and a forced acquiescence: as if already completely crushed in spirit by the vexation of poverty, he seems insensible to being burdened with other misfortunes. We suspect that the parents of the blind man suffered something of this sort, even though their answer on the whole is composed with great plausibility. For every one would agree that the recognition of the man as their son was a matter as to which it was far more reasonable to interrogate them than the man himself, whereas the question as to the Physician was one not so much, for the parents to answer as for him who had experienced the benefit of the wonderful operation. Thus they distinctly acknowledge what they know, inasmuch as they are fairly called upon for this; but what he could tell more truly, since he had the more accurate knowledge, about that they call upon him to give information. And it is not without Divine guidance. I think, that they added to their speech the words: He is of age. For this too seems to indicate the impiety of the Pharisees. Because, if he that received sight was qualified by his time of life to form a sound opinion; when he relates the miracle and how he was treated, he will not speak with the mind of a boy, but with an understanding now well matured, and probably able to support by argument those speakers with whom he agrees. This then will of necessity tend to show the utterly shameless incredulity of…
