Fr. Reginald Marie Garrigou-Lagrange, O.P. (1877-1964) is considered the greatest Catholic theologian of the 20th century. Fr. Garrigou-Lagrange came to the attention of Catholic scholars early in the last century, when he wrote against Modernism. Knowing that Modernism---which denied the objective truth of Divine revelation and taught an heretical conception of the evolution of dogma---attacked the very heart of the Catholic faith, Fr. Garrigou-Lagrange authored what are now classic works on apologetics, in defense of the Catholic Faith by way of both philosophy and theology. He taught at the Angelicum in Rome from 1909 to 1960, and served as a consultor to the Holy Office and other Roman Congregations for several years. He is most famous, however, for his works, an astonishing 500 books and articles. In these he has demonstrated that he is a true son of St. Thomas Aquinas [full-color picture above] in the classic Dominican tradition. The sepia image of Fr. Lagrange is one of the few of the theologian in later life that does not feature the glasses he often wore.
Fr. Garrigou-Lagrange was best known for his spiritual theology, especially for insisting "that all are called to holiness and for zealously propounding the thesis that infused contemplation and the resulting mystical life are in the normal way of holiness or Christian perfection. His classic work in this field---and his overall masterpiece---is The Three Ages of the Interior Life, in which the Catholic Faith stands out in all its splendor as a Divine work of incomparable integrity, structure and beauty, ordered to raise man to the Divine life of grace and bring to flower in him the "supernatural organism" of Sanctifying Grace and the Seven Gifts of the Holy Ghost---the wellsprings of all true mysticism. Among his other famous theological works are The Three Ways of the Spiritual Life, Christian Perfection and Contemplation (a forerunner of The Three Ages of the Interior Life), The Love of God and the Cross of Jesus, The Mother of the Saviour and our Interior Life, and Christ the Saviour."
