He is best known for his spiritual theology. His
magnum opus in the field is
The Three Ages of the Interior Life (Les trois ages de la vie int
érieure), in which he propounded the thesis that infused
contemplation and the resulting
mystical life are in the normal way of holiness of
Christian perfection. This influenced the section entitled "Chapter V: The Universal Call to Holiness in the Church" in the
Second Vatican Council's Dogmatic Constitution on the Church,
Lumen gentium. He synthesized the highly abstract writings of
St. Thomas Aquinas with the experiential writings of
St. John of the Cross, attempting to show they are in perfect harmony with each other. Father Garrigou-Lagrange, the leading proponent of "strict observance
Thomism", attracted wider attention when in 1946 he wrote against the
Nouvelle théologie theological movement, criticizing elements of it as
Modernist. He is also said to be the drafter of
Pope Pius XII's 1950
encyclical Humani generis, subtitled "Concerning Some False Opinions Threatening to Undermine the Foundations of Catholic Doctrine". In politics, like many neo-scholastic theologians of his time, Garrigou-Lagrange was a strong supporter of the far-right movement
Action Française and he also sympathized with
Vichy France. In 1941 he praised the
French collaborationist regime and its Chief of State
Pétain in a letter written to his former disciple
Jacques Maritain: "I am entirely with the
Marshal, I see him as the Father of the
patrie, blessed with a good sense verging on genius, and as a truly providential man". Maritain described Garrigou-Lagrange as "valiantly fighting for Vichy," while Maritain's anti-Vichy student
Yves Simon wrote of Garrigou-Lagrange, "If I did not hold the sacerdotal role in such respect I would write to him that I would hold him responsible if some misfortune comes to any of my Jewish friends". Indeed, Garrigou-Lagrange went so far as to declare in a letter that for a Catholic to support
de Gaulle would be a mortal sin. However, as Matthew K. Minerd, Ph.D., states in an interview, Garrigou-Lagrange's support for the Vichy regime reflected a Catholic reaction against the French Revolution and the Republic, especially its anti-clericalism. Furthermore, in Garrigou-Lagrange's remarks on Pétain, Dr. Minerd has not found a single antisemitic statement. Garrigou-Lagrange also admitted a lack of engagement with political questions and acknowledged that politics was his weakest area. ==Influence==
