Caesarius of Arles, on Gen 3:14

“And the Lord God said to the serpent: Because thou hast done this thing, thou art cursed among all cattle, and beasts of the earth: upon thy breast shalt thou go, and earth shalt thou eat all the days of thy life.”

“God said to the devil: "Dust you shall eat." Is it the earth that we tread underfoot that the devil eats, brethren? No, it is people who are earthly minded, sensual and proud, who love the earth and place all their hopes in it. They labor entirely for carnal advantages, rather for such pleasures, and think little or nothing of the salvation of their souls. People like these, then, the devil seeks. He seems to do so justly, for they were assigned to him at the beginning of the world when it was said to him, "Dust you shall eat." Therefore let each one look to his own conscience. If he sees that he has greater care for his body than for his soul, let him fear that he will become the food of the serpent.”
