It follows that the serpent in paradise was certainly not brought into being without the will of God. In the figure of the serpent we see the devil. That the devil existed even in paradise we are informed by the prophet Ezekiel, who in discussing the prince of Tyre says, “You are in Eden, the garden of God.” The prince of Tyre stands for the devil. Shall we, therefore, accuse God because we cannot comprehend the treasures—with the exception of those that he has deigned to reveal—of his majesty and wisdom that lie hidden and concealed in Christ? Yet he did reveal to us the fact that the wickedness of the devil is fruitful for humanity’s salvation. This would not be the devil’s intention, but the Lord makes the wickedness of him who stands in opposition to us contribute something to our salvation. The wickedness of the devil has caused the virtue and patience of one holy man to shine in a clearer light—St Ambrose of Milan
