Underground church

The term underground church (Chinese: 地下教会; pinyin: dìxià jiàohuì) is used to refer to Chinese Catholic churches in the People's Republic of China which have chosen not to associate with the state-sanctioned Chinese Patriotic Catholic Association. Underground churches came into existence in the 1950s, after the communist party's establishment of the People's Republic of China, due to the severing of ties between Chinese Catholics and the Holy See.

There continues to be tensions between underground churches and "open churches" which have joined the state-sanctioned Chinese Patriotic Catholic Association (Chinese: 中国天主教爱国会; pinyin: Zhōngguó Tiānzhǔjiào Àiguó Huì).

The description of an "underground church" reflects language that was made popular during the Cold War, when these churches came about. Underground churches are also sometimes referred to as "Vatican loyalists" because they have attempted to remain loyal to the Pope and the Holy See. There is no established organization structure of underground churches, though they tend to be clustered around a number of Vatican-ordained bishops. However, underground churches would in 1989 form the Bishops Conference of Mainland China (Chinese: 天主教中国大陆主教团; pinyin: Tiānzhǔjiào Zhōngguó Dàlù Zhǔjiào Tuán) as separate from the state-sanctioned Bishops Conference of Catholic Church in China (Chinese: 中国天主教主教团; pinyin: Zhōngguó Tiānzhǔjiào Zhǔjiào Tuán), which was established in 1980.
