Seven leading cultural observers examine several regions and several religions and explain the resurgence of religion in world politics. Peter L. Berger opens with a global overview. The other six writers deal with particular aspects of the religious scene: George Weigel, with Roman Catholicism;David Martin, with the evangelical Protestant upsurge not only in the Western world but also in Latin America, Africa, the Pacific rim, China, and Eastern Europe; Jonathan Sacks, with Jews and politics in the modern world; Abdullahi A. An-Na'im, with political Islam in national politics and international relations; Grace Davie, with Europe as perhaps the exception to the desecularization thesis; and Tu Weiming, with religion in the People's Republic of China.
