Réginald Marie Garrigou-Lagrange, O.P. (February 21, 1877, Auch, France – February 15, 1964, Rome) was a Catholic theologianand, among Thomists of the scholastic tradition, is generally thought to be the greatest Catholic Thomist of the 20th century^{[citation needed]}. Outside the ranks of Thomists of that sort, his reputation is somewhat more mixed. He taught at the Pontifical University of St. Thomas Aquinas, commonly known as the Angelicum, in Rome from 1909 to 1960.

By 1917 a special professorship in ascetical and mystical theology was created for him at the Angelicum, the first of its kind anywhere in the world. His great achievement was to synthesise the highly abstract writings of St Thomas Aquinas with the experiential writings of St John of the Cross, showing how they are in perfect harmony with each other.^[1]

Father Garrigou-Lagrange, the leading proponent of "strict observance Thomism," initially attracted attention when he wrote against the Modernist Nouvelle Théologie theological movement.^[2] He is also said to be the drafter or "ghostwriter" of Pope Pius XII's 1950encyclical Humani Generis, subtitled "Concerning Some False Opinions Threatening to Undermine the Foundations of Catholic Doctrine."^[3]

He is best known for his spiritual theology. His magnum opus in the field is The Three Ages of the Interior Life, in which he propounded the thesis that infused contemplation and the resulting mystical life are in the normal way of holiness of Christianperfection. 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.^[4]

He taught many eminent Catholic theologians during his academic career, the most illustrious being the future Pope John Paul II, whose encyclical Fides et Ratio is the mature fruit of his training under the learned Dominican. Fr. Garrigou-Lagrange is also known to have introduced Thomism to fellow theologian and priest Yves Congar.
