Auguste Sabatier (born Oct. 22, 1839, Vallon, Fr.—died April 12, 1901, Paris) was a French Protestant theologian and educator who helped popularize biblical interpretation by applying methods of historical criticism. He also promoted the development of liberal Protestant theology and the Roman Catholic Modernist movement by his interpretation of Christian doctrine as the symbolism of religious feelings. Among his principal writings that have been translated into English are The Apostle Paul (1891), Outlines of a Philosophy of Religion (1897), and Religions of Authority and the Religion of the Spirit (1904).
