BEIJING — Chinese authorities have released the pastor of the country’s largest Protestant mega-church after he was detained for more than two months following protests against the government’s removal of crosses from churches, a church worker said Friday. Despite gaining his freedom, Joseph Gu Yuese has been confined to his home since his March 31 release and barred from meeting or communicating with others without permission, according to a U.S.-based Christian group. Gu was formally arrested on Feb.
