Wis 19:17

“It rightly says that they were stricken with blindness, like those who were blinded by the darkness and wandered before the door of the righteous one—that is, of Lot—looking for the door's opening without finding it. In fact, whoever suffers interiorly because of the darkness of error is surrounded on all sides by extremely grave dangers, since he does not know the way to life. And nor can one who errs find that door who says in the Gospel, "I am the door. If someone enters through me, he will be saved. He will come in and go out and find pasture."”

“Just as in the instrument of the organ, different sounds differ from each other, but musicians agree to temper them for the harmony of the melody, so also, although the various elements differ from each other in quality, they are nevertheless bent to the will of their Creator, preserving the law of their nature; for our Maker did not create His creation contrary to Himself, but made it in all things conformable to His will.”

“(Vers. 16.). But they were struck, namely the Egyptians, with blindness, namely corporeal, through the plague of darkness, of which Exodus ten; and spiritual, through the blinding of the mind, so that amid the scourges they became worse: Exodus seven: "The heart of Pharaoh was hardened," etc. As those, namely the unspeakable Sodomites, on account of their unspeakable sin, which they themselves committed: Romans one: "God delivered them over to shameful passions." At the doors of the just man, namely Lot, of whom Second Peter two: "In sight and hearing he was just." They, I say, when they were covered with sudden darkness, namely aorasia, or non-seeing, struck by the Angel, each one, namely of them, the passage of his door, namely Lot's, sought, and could not find it: whence Genesis nineteen: "Those who were outside they struck with blindness, from the least to the greatest, so that they could not find the door."”
