Catena Aurea · Lukasevangelium 18
And it came to pass, that as he was come nigh unto Jericho, a certain blind man sat by the way side begging: And hearing the multitude pass by, he asked what it meant. And they told him, that Jesus of Nazareth passeth by. And he cried, saying, Jesus, thou Son of David, have mercy on me. And they which went before rebuked him, that he should hold his peace: but he cried so much the more, Thou Son of David, have mercy on me. And Jesus stood, and commanded him to be brought unto him: and when he was come near, he asked him, Saying, What wilt thou that I shall do unto thee? And he said, Lord, that I may receive my sight. And Jesus said unto him, Receive thy sight: thy faith hath saved thee. And immediately he received his sight, and followed him, glorifying God: and all the people, when they saw it, gave praise unto God. Now for this reason He asks what the blind man wished, that He might stir up his heart to prayer, for He wishes that to be sought in prayer, which He knows beforehand both that we seek and He grants.
(ubi sup.) The blind man seeks from the Lord not gold, but light. Let us then seek not for false riches, but for that light which together with the Angels alone we may see, the way whereunto is faith. Well then was it said to the blind, Receive thy sight; thy faith hath saved thee. He who sees, also follows, because the good which he understands he practises.
