Alphonsus Liguori sometimes called Alphonsus Maria Liguori was an Italian Catholic bishop, spiritual writer, composer, musician, artist, poet, lawyer, scholastic philosopher, and theologian.
He founded the Congregation of the Most Holy Redeemer (the Redemptorists). In 1762 he was appointed Bishop of Sant’Agata dei Goti. A prolific writer, he published nine editions of his Moral Theology in his lifetime, in addition to other devotional and ascetic works and letters.
Among his best known works are The Glories of Mary and The Way of the Cross, the latter still used in parishes during Lenten devotions.
