Augustine of Hippo

(Tr. xliv. 16, 17) The day then was divided between light and darkness. So it is rightly added, that they which see not, may see; for He relieved men from darkness. But what is that which follows: And that they which see might he made blind. Hear what comes next. Some of the Pharisees were moved by these words: And some of the Pharisees which were with Him heard these words, and said unto Him, Are we blind also? What had moved them were the words, And that they which see might be made blind. It follows; Jesus saith unto them, If ye were blind, ye should have no sin; i. e. If ye called yourselves blind, and ran to the physician. But now ye say, We see; therefore your sin remaineth: for in that saying, We see, ye seek not a physician, ye shall remain in your blindness. This then which He has just before said, I came, that they that see not might see; i. e. they who confess they cannot see, and seek a physician, in order that they may see: and that they which see not may be made blind; i. e. they which think they can see, and seek not a physician, may remain in their blindness. This act of division He calls judgment, saying, For judgment have I come into this world: not that judgment by which He will judge quick and dead at the end of the world.
