This contribution to the forthcoming book Law and the Christian Tradition in Latin America: Biographies (London, Routledge, 2020, Rafael Domingo and Matthew Mirow, eds.) presents Professor German Jose Bidart Campos. A towering figure of Argentine Constitutional Law, Bidart Campos was at the same time a conscientious Christian. His religious beliefs, nevertheless, were ocassionally in tension with some of the policy positions he adopted, especially in his later years. This article attempts to prove that, notwithstanding that tension, Bidart Campos persevered to the end in reconciling constitutional conviction with Catholic dogma.
