Alphonsus Liguori (1696 – 1787) was an Italian Catholic bishop, theologian, and founder of the Redemptorist order. He was a prolific writer, composer, and philosopher, known for his contributions to moral theology. Liguori is also recognized as the patron saint of confessors.
Born near Naples, he excelled in law but abandoned it to become a priest in 1726. Liguori worked among the poor, emphasizing simple and clear preaching. He founded the Redemptorists in 1732, focusing on missions for the most neglected communities. His sermons and writings addressed moral theology, opposing legalistic rigidity while promoting a balanced approach to faith.
Appointed Bishop of Sant'Agata de’ Goti in 1762, he reformed the clergy and helped the poor. Liguori wrote over 100 works, including The Moral Theology (1748). He was canonized in 1839 and declared a Doctor of the Church in 1871. Liguori’s legacy remains central to Catholic teaching.
