Paul Evdokimov (1901-1970) was a well-known writer, professor and lay theologian of the Orthodox Christian Church in France. As professor of moral theology at St. Sergius Orthodox Institute in Paris, a teacher at both the Ecumenical Institute in Geneva and the L'Institut in Paris, and official Orthodox observer at Vatican II, Evdokimov served as a bridge between the tradition of the Eastern Church and the Churches of the West.
