John 9:18-23

However, the Jews did not believe that he had been blind and had received his sight until they called the man’s parents. They asked them, “Is this your son, who you say was born blind? Then how does he now see?” His parents answered, “We know that this is our son, and that he was born blind; but as to how he now sees, we do not know; or who has opened his eyes, we do not know. Ask him [and stop asking us]; he is of age, he will speak for himself and give his own account of it.” His parents said this because they were afraid of [the leaders of] the Jews; for the Jews had already agreed that if anyone acknowledged Jesus to be the Christ, he would be put out of the synagogue (excommunicated). Because of this his parents said, “He is of age; ask him.”
