Believers can also outside the official religious communities to worship and other gatherings take. Religious Communities, said outside the official "patriotic" churches exist but in a legal gray area. These communities are not registered as local concentrations accepted, but not in the manner and in the organization of larger churches. There is the monopoly of China's official churches. The non-registered communities are often described as house churches, but this is somewhat misleading. These communities often gather in a small frame, they also rent larger halls and some "house churches" have their own church.The house churches are no underground churches. The house churches are of the official Protestant church in general, with Bibles, song books and other writings, composed and also the social and charitable work of many of their church members will be recognized.However, the government, the churches not only support but also to control and the non-registered communities criticized the lack of legal certainty in the event of a dispute with local officials.This is a general problem in China, which is currently up in the top Party bodies (see administrative detention). According to Amnesty International, several thousand arrests annually.Other estimates are nearly 1,000 arrests.For more than 25 million members of the House Churches Although these are isolated cases, but it may in cases very well come to arrest. Between the Vatican and the Chinese government is always to dispute, and the Pope has been on a trip to China is not ready, but are now 85% to 90% of the bishops of the official "Chinese Catholic Patriotic Church" recognized by the Vatican and the Pope tries in recent years between the registered Catholics and non-registered Catholics to convey.One problem, both for the churches as well as for the state, is the growing of some very obscure sects, sometimes trying to poach all the house churches. For the Christian communities, the risks posed by these sects are now greater than the risks posed by the government manipulation and control. It tries, through better training of religious leaders to deal with this problem.
