Although Christianity has been a minority religion in Chinese societies, Christians have been powerful catalysts of social activism in seeking to establish democracy and rule of law in mainland China, Taiwan, Hong Kong, and diasporic communities. The chapters gathered in this collection reveal the vital influence of Christian individuals and groups on social, political, and legal activism in Chinese societies. Written from a range of disciplinary and geographical perspectives, the chapters develop a coherent narrative of Christian activism that illuminates its specific historical, theological, and cultural contexts. Analyzing campaigns for human rights, universal suffrage, and other political reforms, this volume uncovers the complex dynamics of Christian activism, highlighting its significant contributions to the democratization of Greater China.
