such prominent Americans as the Firestone family, founders of the Firestone Tire and Rubber Company of Ohio. Though sometimes controversial (the group attracted opposition from the Roman Catholic Church), the group grew into a well-known, informal and international network of people by the 1930s. The London newspaper editor Arthur J. Russell joined the group after attending a meeting in 1931. He wrote For Sinners Only in 1932, which inspired the writers of God Calling. Among those influenced by the Oxford Group and Frank Buchman, one also finds: Paul Tournier, the Swiss physician and author whose Medicine of the Person became a worldwide success Emil Brunner, the Swiss Protestant (Reformed) theologian Theophil Spoerri, a Swiss writer and academic who was instrumental in setting up the Gotthardbund, a civil society organisation which fought against Nazi propaganda in Switzerland from 1940 to 1945. Gabriel Marcel, French philosopher, playwright and leading Christian existentialist Evaluation and critics Carl Jung on the Oxford Group Carl Jung on the matter of an individual and his involvement in the Oxford Group: Published literature critical of the Oxford Group In 1934 Marjorie Harrison, an Episcopal Church member, published a book, Saints Run Mad, that challenged the group, its leader and their practices. The theologian Reinhold Niebuhr criticized Buchman's philosophy and pursuit of the wealthy and powerful. "The idea is that if the man of power can be converted, God will be able to control a larger area of human life through his power than if a little man were converted. This is the logic which has filled the Buchmanites with touching solicitude for the souls of such men as Henry Ford or Harvey Firestone". He called its moral principles "a religious expression of a decadent individualism... bourgeois optimism, individualism and moralism expressing itself in the guise of religion", and added, "no wonder the rather jittery plutocrats of our day open their spacious summer homes to its message!" Confusion with Oxford Movement The Oxford Group is occasionally confused with the Oxford Movement, an effort that began in the 19th-century Anglican Communion to encourage high-church practice and demonstrate the church's apostolic heritage. Though both had an association with members and students of the University of Oxford at different times, the Oxford Group and the Oxford Movement are unrelated.
