Venial Sin

Indeed, so great is the evil of sin, that if, through the blessing of God, this little treatise should be the means of preventing but one venial sin in any one of its readers, it will have accomplished a most glorious task, for it will have prevented an evil far greater (could one but realize it) than the Black Death, the bubonic plague, the earthquake in Tokyo, or even the universal Deluge itself. And we devoutly hope it may prevent not one only but many, and not in one only, but in many readers, which may God grant.
