Peter Chrysologus, on Isa 28:16

“Therefore thus saith the Lord God: Behold I will lay a stone in the foundations of Sion, a tried stone, a corner stone, a precious stone, founded in the foundation. He that believeth, let him not hasten.”

“Therefore, brothers, we should be careful neither to give scandal to others nor to take it ourselves when another gives it. It is scandal that troubles the senses, perturbs the mind, confuses our judgment otherwise sharp. It is a scandal that changed an angel into the devil, an apostle into a traitor; that brought sin into the world and allured humankind to death.… Scandal tempts the saints, fatigues the cautious, throws down the incautious, disturbs all things, confuses all people.… He uttered a warning to keep anyone else from coming to this, by saying, "It is impossible that scandals should not come; but woe to him through whom they come! It would be better for him if a millstone were hung about his neck and he were thrown into the sea, rather than that he should cause one of these little ones to sin."Why a millstone and not an ordinary stone? Because, while a millstone is grinding the grain, and pouring out the flour and separating the bran from the meal, it is simultaneously furnishing bread to those who are dutifully toiling. Rightly, therefore, is a millstone tied to the neck of the person who chooses to be a minister of scandal rather than of peace; the very same thing that should have drawn him to life may drag him down to death. For [such a person] has changed those senses given to aid him toward life into a stumbling block bringing death. Then they persuaded him to see something else, and hear, feel and relish something else than was in Christ and in his saving knowledge. In this way he has encompassed the cornerstone, the stone symbolizing help, the stone cut out without hands, that is, Christ, and he has turned it into a stumbling for the weak.”
