To overcome sin, we must first recognize it in all its disguises. The Seven Deadly Sins (lust, gluttony, avarice, sloth, anger, envy, and pride) must be combatted even in their mildest forms lest they become more serious — and more deadly. This manual provides sound catechesis on sin and excellent advice on what to do about it. A key is to seek growth in the corresponding virtues (e.g., humility instead of pride, temperance instead of gluttony) and, of course, to stay close to the sacraments. This volume looks like a small prayerbook, complete with gilded edges and ribbon, but it reads like essential armor in the battle for our souls.
