Salt and Light presents the life stories of outstanding Chinese Christians who, as early modernizers, promoted China’s nation building and moral progress in the early twentieth century. Lively anecdotes and photographs highlight the strong character of ten pioneers in the modern professions of education, medicine, journalism, and diplomacy. These professionals were motivated by faith to introduce practical social reforms and build up China’s civil society. They modeled and promoted virtues essential to social progress during the golden age of Chinese Protestantism. Their stories touch on themes important in today’s global era: patterns of cooperation between foreign and Chinese partners, the contributions to China of Western-educated professionals, Christianity’s role in furthering East-West understanding and exchanges, and the transnational nature of modern Chinese Christianity. The editors and authors articulate the importance of recovering China’s Christian heritage as part of world Christianity.
