While social revolutionaries endeavoured to make the most out of Bergson, many religious leaders, particularly the more liberal-minded theologians of all creeds, e.g., the Modernists and Neo-Catholic Party in his own country, showed a keen interest in his writings, and many of them found encouragement and stimulus in his work. The Roman Catholic Church, however, banned Bergson's three books on the charge of pantheism (that is, of conceiving of God as immanent to his Creation and of being himself created in the process of the Creation). They were placed on the Index of prohibited books (Decree of 1 June 1914).
