They may number even two or three hundred million, and are growing fast. They are the self-styled Christians in China, who don’t clearly know what they are.
All read the Bible; some claim to be related to Christ, like Hong Xiuquan, the leader of the destructive Taiping Rebellion in the 19th century, which killed 20% of the Chinese population. Most add to the Bible and the Gospels their own tracts, drawing explanations from Buddhist or Taoist traditions. Lots claim to have dreams and visions of God and the apostles, and thus cure people of their ailments for free or small donations, whereas state hospitals charge stiff bills for any patient.
Some Chinese officials argue they can’t be regarded as Christians at all, but just the latest wave of the centuries-old Chinese syncretic tradition of pulling every faith and belief under one roof. But the new styled Chinese Christians claim to be so, perhaps in part because the label brings with it a more tolerant approach from the authorities, who are not against the spread of Buddhism and Christianity, but take much harsher measures against Islam, for fear of Muslim extremists.
In the past syncretism occurred over a period of 500–600 years to Buddhism, which became sinicized by drawing on homegrown Taoism since the first century AD. The same is happening now in China with Christianity; only the time frame is much shorter. Christianity went from about 2–3% of the total population in the late 1990s to presently being possibly as much as 20–30% of the population. The popularity of the Pope is apparently also helping all of this.
Many people hear about the Pope and the Catholic Church and claim to be Catholic, although they may have never attended Catholic mass.
