Stark, a prolific sociologist in the realm of religion, critiques a couple of well accepted theories using recent surveys of global religion. He debunks the secularization theory (that the entire world is marching toward secularization) and other commonly held assumptions about religion in our world.
Dr. Scott Sunquist, Dean of the School of Intercultural Studies at Fuller Theological Seminary, provides a learned overview of major themes in twentieth-century world Christianity. He masterfully shows how such factors as migration, political turmoil, persecution, the decline of Western Christianity, and Pentecostalism have created a religion far different from that of a century ago.
In 1900 many assumed the twentieth century would be a Christian century because Western “Christian empires” ruled most of the world. What happened instead is that Christianity in the West declined dramatically, the empires collapsed, and Christianity’s center moved to Africa, Asia, Latin America, and the Pacific.
