During the Second World War de Lubac joined a movement of "spiritual resistance" assisting in the publication of an underground journal of Nazi resistance called Témoinage chrétien or Christian Witness. Professor and theologian
De Lubac served as a professor of fundamental theology at the Catholic University of Lyon from 1929 to 1961 with two interruptions; the first during World War II when he was forced underground because of his activities with the French Resistance and the second from 1950 to 1958 when the Jesuit order under pressure from Rome removed him from his teaching responsibilities and sent him away from the Jesuit residence at Fourvière.

His writings and doctrinal research played a key role in the shaping of the Second Vatican Council.
