Athanasius of Alexandria

One thing you can count on: Corruption does not save those who get into it. On the contrary, it sets itself up against them, tears them down and brings about their doom. Woe to those people against whom this prophecy is written! For the evil they pursue is sharper than a two-edged sword, and it will first slay those who lay hold of it. Even their own tongue, as the psalmist points out, "is a sharp sword, and their teeth are spears and arrows."
