Heze Diocese covers eight counties, a district, and a development area. The Diocese was separated from the administration of Yanzhou Diocese in 1932, and was erected as an Apostolic Vicariate in 1937. It was made a diocese in the year 1946, and it came under the care of the Society of the Divine Word (SVD) until the 1950s. According to Vatican’s Annuario Pontificio, Heze had the largest number of Catholics—72,000, among the other 10 dioceses in Shandong, before the establishment of People’s Republic of China (PRC) in 1949. All foreign missioners were expelled and the local clergy were persecuted in the 1950s.
There had been more than 30 churches, including a beautiful cathedral, but by the time of the Cultural Revolution (1966-76), all of them were damaged or demolished. Heze went decades with no clergy as well as no church. When Bishop Wang Dianduo was ordained the bishop of Heze in 2000, the diocese did not have a single church, and there was only one priest assisting the bishop. The Rosary Church was built in 2001, and it was the only major place of worship in the diocese.
Heze has a population of 8.98 million.
Mandarin and Shandong dialect are in use.
