Catholicism was introduced by western missioners during the Qing dynasty 1605. Yidu was first placed under the Archdiocese of Jinan in 1806 and later covered by the Diocese of Yantai. In 1931, the apostolic prefecture of Yidu was established and was first managed by the French Franciscan friars. The first prefect was Father Eugene Venance Guichard, OFM.
The Vatican's Annuario Pontificio 2007 (the Pontifical Yearbook) lists Yidu as an apostolic prefecture, but China?s government-sanctioned "open" Church recognizes it as a diocese. In 2006, there were 6 priests and 2 nuns serving about 10,000 Catholics. There are 5 seminarians and 2 postulants.
The last ordinary was Bishop Joseph Sun Zhibin. He was born to a Catholic family on April 1, 1911, in Linqu county, where Catholicism was introduced as early as in 1605. He received priestly formation in the minor and major seminaries in the neighboring dioceses in Shandong. He was ordained to priesthood in 1939. He was in prison for his faith during 1953-56 and was sent to reform-through-labor in Yidu 1966-1972 during the Cultural Revolution (1966-1976). Ordained on April 24, 1988, Bishop Sun was among the five "self-elected and self-ordained" bishops in Shandong province. He was later legitimized by the Vatican. He passed away on Oct. 23, 2008 at the age of 97.
