Saint Alphonsus Maria De liguori
Born to the nobility, he was a child prodigy, was extremely well-educated, and received his doctorate in law from the University of Naples at age 16. He had his own practice by age 21, and was soon one of the leading lawyers in Naples, though he never attended court without having attended Mass first. He loved music, could play the harpsichord, and often attended the opera, though he frequently listened without bothering to watch the over-done staging. As he matured and learned more and more of the world, he liked it less and less, and finally felt a call to religious life. He declined an arranged marriage, studied theology, and was ordained at age 29.
Noted for his simple, clear, direct style of preaching, and his gentle, understanding way in the confessional. Writer on asceticism, theology, and history; master theologian.
Alphonsus vowed early to never to waste a moment of his life, and lived that way for over 90 years. Declared a Doctor of the Church by Pope Pius IX in 1871.
