St John's Cathedral,[a] today known as Gospel Church,[b] is a Protestant church situated on Yangtianjing Street in the county-level city of Langzhong, Nanchong, Sichuan Province.

[4] It has been subjected to the control of the state-sanctioned Three-Self Patriotic Church since 1954.

The first Anglican church in Langzhong (then known as Langchung, Paoning or Paoning Foo [Baoning / Baoning Fu]), the Trinity Church, built in 1893, had become too small as the number of converts had increased.

[3][5] After a series of problems, St John's was eventually built on Yangtianjing Street, under the supervision of William Cassels, one of the Cambridge Seven, and the then missionary bishop in the Diocese of Western China.

[6] The cathedral was designed by the Australian architect George A. Rogers, and built in the fusion of neo-Gothic and traditional Sichuanese architectural styles.
