"By the breaking of the bread, he makes it into a seedbed of food--for if the bread had been left intact and not pulled apart and broken into pieces, they would have been unable to feed the great crowds of men, women, and children...Mysteries are made manifest, so that what did not feed the multitude of people in its original whole and unbroken state now feeds them in its divided state."
