Roman Catholic Diocese of Mariannhill
The Roman Catholic Diocese of Mariannhill () is a diocese located in the city of Mariannhill in the Ecclesiastical province of Durban in South Africa. History
In 1880, at the request of Bishop James David Ricards of the Eastern Vicariate of the Capeof Good Hope, Trappist Franz Pfanner abbot of Mariastern Abbey in Banja Luka, Bosnia and Herzegovina, established a monastery near Sundays River Valley, South Africa. Due to drought and wind the site proved unsuitable and with the permission of Bishop Charles Jolivet, O.M.I., of the Natal Vicariate, Pfanner and his companions relocated to a part of the Zoekoegat farm, near Pinetown. He named it Mariannhill after St. Mary and St. Anne. As their missionary activity was not entirely compatible with the contemplative focus of the Trappists, in 1909 upon the recommendation of Edmond Obrecht, abbot of the Abbey of Our Lady of Gethsemani, the Holy See separated the monks of Mariannhill from the Trappists, forming the Congregation of the Missionaries of Mariannhill (CMM). In 1904 Henri Delalle C.M.M. was appointed appointed Apostolic vicar for Natal. On September 10, 1921 the Apostolic Vicariate of Mariannhill was established from the Apostolic Vicariate of Natal. The first apostolic vicars were members of the CMM. The Diocese of Mariannhill was erected on January 11, 1951 as suffragan to the Metropolitan Archdiocese of Durban. The Diocese measures 12,612 square kilometers. As of 2017, the diocese had a population of about 329,575 Catholics. St. Joseph’s Cathedral was built in 1908, and is the seat of the Bishop of Mariannhill. Bishop Adalbert Fleischer founded the Franciscans Familiars of St. Joseph’s (FFJ). Paul Themba Mngoma was appointed bishop on March 14, 1981; he was the first African Bishop of the Mariannhill Diocese. Mngoma worked to increae the number of indigenous clergy. In response to a request from Bishop Pius Dlungwane for an Apostolic Visitation, Pope Francis appointed the Archbishop Emeritus of Pretoria in South Africa, William Slattery O.F.M. to visit Mariannhill and meetings and consult with the clergy, religious and laity of the Diocese. As a result of the visitation, in September 2020, Slattery was named apostolic administrator of the diocese, while Biahop Dlungwane remained its spiritual head. In December 2021, Mons. Neil Augustine Frank, Provincial Superior of OMI in South Africa, was appointed Coadjutor Bishop. Frank noted that Marianhill is  almost completely a Zulu speaking Diocese, "...and this is great for the inculturation of the faith." Bishop Mlungisi retired in October 2022. Bishops
