by Fr. Alphonsus Rodriguez, SJ. In this classic spiritual treatise, Fr. Alphonsus Rodriguez puts us on guard against one of the most subtle and devasting snares laid by the enemy of our salvation: vainglory: “All the saints admonish us to be much on our guard against vainglory, because, say they, it is a cunning thief which often steals from us even our best actions, and which insinuates itself so secretly that it has even robbed and despoiled us before we perceive it... The malice of this vice consists in this, that the vainglorious man endeavors to walk off with the glory and honor that belong to God alone.” The remedy to this insidious vice is to cultivate purity of intention, and in this treatise, Fr. Rodriguez shows us how to do so. This little book is a must-read for anyone who wishes to attain holiness.
