Pseudo-Chrysostom — as excerpted in the Catena Aurea on Matthew 21:10-16

“As though He had said, Be it so, it is My fault that these cry thus. But is it My fault that so many thousand years before the Prophet foretold that so it should be? But babes and sucklings cannot know or praise any one. Therefore they are called babes, not in age, but in guilelessness of heart; sucklings, because they cried out being moved by their joy at the wonderful things they beheld, as by the sweetness of milk. Miraculous works are called milk, because the beholding of miracles is no toil, but rather excites wonder, and gently invites to the faith. Bread is the doctrine of perfect righteousness, which none can receive but they who have their senses exercised about spiritual things.”
