John Chrysostom
"This is the stone rejected by you builders, which has become the chief cornerstone." He reminded them also of a saying sufficient to frighten them, for it is said: "He who falls on this stone will be broken; but on whomever it falls, it will crush him" (Mt 21:44). "And there is salvation in no one else." What wounds do you think they received from these words? Then, showing that they had dealt thus with a precious stone, he adds: "which has become the chief cornerstone." That is, the stone precious and genuine by nature has been rejected by you. So greatly did the miracle impart boldness to them.
