John 9:17

We must go over the Scriptures not in a chance way or carelessly, but with all exactness, that we be not entangled. Since even now in this place one might with show of reason question, how, when they had asserted, "This man is not of God, because he keepeth not the Sabbath," they now say to the man, "What sayest thou of him, that he hath opened thine eyes?" and not, "What sayest thou of him, that he hath broken the Sabbath?" but put now that which was the ground of the defense, not that of the accusation. What then have we to reply? That these (who speak) are not the men who said, "This man is not of God," but those who separated themselves from them, who also said, "A man that is a sinner cannot do such miracles." For desiring to silence their opponents the more, in order that they may not seem to be partisans of Christ, they bring forward the man who had received proof of His power, and question him. Observe now the wisdom of the poor man, he speaketh more wisely than them all. First he saith, "He is a Prophet"; and shrank not from the judgment of the perverse Jews who spake against Him and said, "How can this man be of God, not keeping the Sabbath?" but replied to them, "He is a Prophet."

(Tr. xliv. 9) Or they sought how they could throw reproach upon the man, and cast him out of their synagogue. He declares however openly what he thinks: He said, He is a Prophet. Not being anointed yet in heart, he could not confess the Son of God; nevertheless, he is not wrong in what he says: for our Lord Himself says of Himself, A prophet is not without honour, save in his own country. (Luke 4:24)

"They say then unto the blind man again, What sayest thou of him who hath opened thine eyes?" What is thy feeling about him? what is thine opinion? what is thy judgment? They sought how to revile the man, that he might be cast out of the synagogue, but be found by Christ. But he steadfastly expressed what he felt. For he said, "That he is a prophet." As yet, indeed, anointed only in heart, he does not thus far confess the Son of God, and yet he speaks not untruthfully. For the Lord saith of Himself, "A prophet is not without honor, save in his own country."

See with what good intent they put the question. They do not say, What sayest thou of Him that keepeth not the sabbath, but mention the miracle, that He hath opened thine eyes; meaning it would seem, to draw out the healed man himself; He hath benefited them, they seem to say, and thou oughtest to preach Him.
