Pastor Wang Yi of the Early Rain Covenant Church, one of China’s most prominent unofficial churches, has been criminally detained for allegedly inciting subversion of state power, according to his mother. The church in Chengdu, in Sichuan province, was raided at around 6pm on Sunday, and more than 100 leaders, seminary students and worshippers were taken into custody. Some were taken from their homes or the streets. Church members also said they were abused while in police custody. The whereabouts of Wang’s wife, Jiang Rong, are not known. She was removed from her mother-in-law’s home on Sunday night. Chen Yaxue, Wang’s 73-year-old mother, told the South China Morning Post that Chengdu police went to her flat on Wednesday morning. “They brought along an arrest notice asking me to sign. It said my son has been placed under criminal detention for allegedly inciting subversion of state power,” Chen said. 100 Christians snatched in overnight raids on underground church She said she did not understand what that meant so did not sign the document. According to China’s criminal code, the charges could result in a sentence of up to five years, but up to 15 years in extreme cases. Wang has yet to be allowed to meet lawyers or family members. Chen said she and her 11-year-old grandson were under round-the-clock surveillance by three to four security personnel outside her home. “They follow us whenever and wherever we go,” she said. “The surveillance has taken a huge toll on my grandson. He is emotionally shocked with [his parents taken away]. He has not slept for two nights.” The surveillance has taken a huge toll on my grandson. He is emotionally shocked … He has not slept for two nights Chen Yaxue, Wang Yi’s 73-year-old mother “I’m very sad and confused, not sure what to think now. I just want to take my grandson to Xishaungbana [in Yunnan province] to run away from all this madness.” Chen said police escorted her grandson and Wang’s wife to her home at around 8pm on Sunday to arrange care for the boy. Jiang was allowed to stay for only two hours. Chen said local community officers kept pressuring her to send her grandson to a nearby school. The boy was previously a student of a primary school run by the raided church. Meanwhile, Wang’s assistant Li Yingqiang, who had been posting updates about the crackdown online, has been criminally detained for allegedly picking a quarrel and inciting trouble on the internet, according to members of the church. Ge Yingfeng, a church staff member, and Lu Jinheng, a church member, were detained for alleged illegal operations. The Chengdu city government did not respond to requests for comment. Chinese underground church raided ahead of Tiananmen service Two days after Wang was taken away, church members released an open letter he wrote in September. He had given instructions that the document be publicised if he went missing for more than 48 hours. In it, the pastor said he would use non-violent methods to stand by his faith and oppose the laws that he said were against the Bible and God, including those that allowed crackdowns on churches. “My saviour Christ also requires me to joyfully bear all costs for disobeying wicked laws,” Wang wrote. Before becoming a pastor, Wang was a human rights activist and a constitutional scholar. His reputation reaches far overseas, especially among the Chinese Christian community. In 2006, Wang met then US president George W Bush in the White House. The round-up in Chengdu is part a broader crackdown on unofficial or underground churches that Beijing has escalated this year. The moves were bolstered by amendments to the Religious Affairs Regulation that gave grass-roots officials more power to act against churches and impose tougher penalties for “unauthorised religious gatherings”. While most of China’s Protestant house churches operate underground, the Early Rain congregation openly practises its faith, posting sermons online and evangelising on the streets. It has about 500 followers but its weekly gatherings spread across more than a dozen meeting points around Chengdu, attracting more than 800 congregants each week, according to church leaders. It also has about 100 seminary students and a primary school catering to about 40 children.
