This paper examines the correspondence of Li Zibiao (1760–1826), a Chinese Catholic priest trained in Naples who worked as a missionary in North China. Whereas existing studies of Chinese theology mainly focus on contextualisation, Li responded to persecution by thinking in global terms and de-emphasising differences between Europe and China. Using developments in casuistry and the moral theology associated with Alphonso de Liguori he was able to avoid the strictures of the Chinese Rites Controversy. His story enriches the history of indigenous clergy in China and suggests some of the roots of China's resilient rural Catholicism.
