John 9:13

(Hom. lvii. 2) The Jews, whom they asked, Where is He? were desirous of finding Him, in order to bring Him to the Pharisees; but, as they could not find Him, they bring the blind man. They brought to the Pharisees him that aforetime was blind; i. e. that they might examine him still more closely.

"They brought to the Pharisees him who had been blind. And it was the Sabbath when Jesus made the clay, and opened his eyes. Then again the Pharisees also asked how he had received his sight. And he said unto them, He put clay upon mine eyes, and I washed, and do see. Therefore said some of the Pharisees;" not all, but some; for some were already anointed. What then said those who neither saw nor were anointed? "This man is not of God, because he keepeth not the Sabbath." He it was rather who kept it, who was without sin. For this is the spiritual Sabbath, to have no sin. In fact, brethren, it is of this that God admonishes us, when He commends the Sabbath to our notice: "Thou shalt do no servile work." These are God's words when commending the Sabbath, "Thou shalt do no servile work." Now ask the former lessons, what is meant by servile work; and listen to the Lord: "Every one that committeth sin is the servant of sin." But these men, neither seeing, as I said, nor anointed, kept the Sabbath carnally, and profaned it spiritually. "Others said, How can a man that is a sinner do such miracles?" These were the anointed ones. "And there was a division among them." The day had divided between the light and the darkness.

It fell to the Pharisees to confirm or deny the miracle.
