Since the reform and opening-up era, the biggest religious change in China has been the rise of Christianity (Protestantism). (According to China’s current policies and regulations, Christianity generally refers to Protestantism, rather than other denominations, e.g., Catholicism or Eastern Orthodox beliefs.) According to the “Basic Viewpoints and Policies on Religious Issues during China’s Socialist Period,” which was released by the CPC in 1982, there were some 700,000 followers of Protestantism in China in 1949. By 1982, there were around three million followers. When it was published in 1997, the Current Situation on the Freedom of Religious Beliefs in China (the first “White Book on Religion”) said that there were 10 million Protestants in the country. In 2018, the second White Book was published, and this said there were 38 million Protestants in China. Protestantism is one of the top five religions in China (the major religions practiced in China are Buddhism, Taoism, Islam, Catholicism, and Protestantism), but it was the last religion to be introduced into the country. It has become the second-largest religion after Buddhism. Protestants have formed a “national presence and local settlements.” During China’s 40 years of reform and opening-up, Protestantism prospered in China. It grew at an average rate of 6.5% annually (Lu 2014). Therefore, religion has become an important topic in Chinese Sociology, and those who specialize in religion seek to understand why it has become so influential.
