John de Lugo, S.J. (Spanish: 1583-1660) taught theology and brought to the lecture halls of the College of Valladolid elegant expression, clear expositions and profound doctrine. John taught at the Roman College from 1621-1643 and then was made a cardinal. The cardinalate did not please him since he had to leave his theological research. One of his works was Justice and Law which was highly lauded by St. Alphonsus Liguori because of its lucid reasoning and accurate judgment. This book had a great influence on other theologians. John published little of the vast amount of material he had prepared because he was a perfectionist, polishing his works constantly. (Ban, Ham, JLx, Som)
