St. Alphonsus Liguori, the Prince of Moral Theologians, was one of the greatest preachers in Church history. A religious founder, consummate theologian, and holy man of God, Saint Alphonsus never fails to utter a stirring word that draws out a lively penitence and redoubled dedication to the work of God from his audience. The Sermons of Saint Alphonsus Liguori contains sermons tailored to the traditional liturgy of the Roman Church for each Sunday in the year. Here, then, is the complete collection of St. Alphonsus’s holy words of admonition.

Resonating throughout these sermons is the profound sense of sin and its awfulness that St. Alphonsus undoubtedly feels and from which he longs to save his flock. He dwells repeatedly on the Four Last Things: Death, Judgment, Hell, and Heaven, bringing the reader to consider his own eternal destiny. Above all, St. Alphonsus’s sermons are permeated by what seems a prolonged meditation on the words of Our Lord: “What doth it profit a man if he gain the whole world and suffer the loss of his own soul?”

And yet, though St. Alphonsus can be a terrible and grave man to hear, it is only from the most unique tenderness and subtlety of his heart that such words can spring. For “out of the fullness of the heart, the mouth speaketh,” and St. Alphonsus’s heart is filled to the brim only with genuine desire for innocence and purity of heart in all his spiritual children. It is worth noting he never refused absolution to anyone in his life.

There is no better teacher on moral theology to ever grace the Church than St. Alphonsus Liguori. Let The Sermons of Saint Alphonsus Liguori guide you away from the mortal error of indifference to sin and into the joyful light and beatitude of holy suffering.
