Cardinal Henri de Lubac (February 20, 1896–September 4, 1991) is considered one of the outstanding theologians of the twentieth century. He was born in France and became a Jesuit priest in 1927. He taught theology at the Catholic University of Lyon from 1929 to 1961. His courses were interrupted twice, once by World War II and again from 1950 to 1958 over a disagreement with Pope Pius XII on certain points of dogma. After these “dark years” ended de Lubac was returned to teaching and grew in influence as a theologian. He was instrumental in shaping the Second Vatican Council and admired by successive pontiffs, eventually accepting an appointment to the cardinalate from Pope John Paull II. He wrote numerous books on spiritual and theological topics including The Christian Faith, Aspects of Buddhism, Catholicism, Corpus Mysticum, and The Eternal Feminine: A Study on the Poem by Teilhard de Chardin.
