Officially, China recognized five religions—Taoism, Buddhism, Islam, Catholicism, and Protestantism—and believers could worship in state-controlled settings. More than twenty million Catholics and Protestants attended churches run by the Chinese Catholic Patriotic Association, and its counterpart the Three-Self Patriotic Movement. But more than twice that number worshipped in unregistered “house churches,” which ranged in size from small farmhouse study groups to large semipublic congregations in the cities.
