All these evil things come from within, and defile the man.
All Commentaries on Mark 7:23 Go To Mark 7
Augustine of Hippo
AD 430
For some things are joined to others in such a way as both to change and be changed, just as food, losing its former appearance, is both itself turned into our body, and we too are changed, and our strength is refreshed by it. Further, a most subtle liquid, after the food has been prepared and digested in our veins, and other arteries, by some hidden channels, called from a Greek word, pores, passes through us, and goes into the draught. Wherefore it goes on: “And He said, That which cometh out of a man, that defileth a man.”
