St. Alphonsus Liguori's Moral Theology has long been praised and held in the highest regard by the Church, covering every moral question of his day. Mediatrix Press is pleased to bring you the first English Translation of this excellent work, once widely read but relegated to obscurity on account of the loss of Latin fluency in Western Society. Volume 1 embraces the first three Books of Alphonsus' Moral Theology.

Bl. Pope Pius IX declared: "Focusing his mind on the glory of God and the spiritual salvation of men he wrote many books, related with holy erudition and piety, whose opinions were between those embraced by both more lax and rigid theologians, to fortify the safe path by which the confessors of Christ's faithful could advance without dashing their foot upon a stone.
