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, Bl. Pope Pius IX declared: “It happened, not without the most provident counsel of God almighty, that since the doctrine of the Jansenist innovators turned all eyes to themselves, enticing many to the sight of their error and leading them over to it, it was then that Alphonsus Maria Liguori stood up, the founder of the Congregation of the Most Holy Redeemer and the Bishop of St. Agatha of the Goths, who, ‘fighting the good fight, opened his mouth in the midst of the Church’; and by his learned writings and labors eradicated this plague, roused from hell, and saw to it tear it out and so exterminate it from the field of the Lord. Not only did Alphonsus appoint these shares for himself, but 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; whether to train and establish the clergy, or to confirm the truth of the Catholic faith and to defend against the heretics of every kind or name; or to assert the laws of this Apostolic See; or to rouse the souls of the faithful to piety.” [Apostolic Letter Honoring St. Alphonsus with the title of Doctor of the Church]
