Diocese of Hildesheim

What Diocese of Hildesheim does

The Diocese of Hildesheim (Bistum Hildesheim) is a Roman Catholic diocese and Körperschaft des Öffentlichen Rechts (public-law corporation) headquartered at Domhof 18-21, 31134 Hildesheim, Germany. Founded in 815 by Emperor Louis the Pious, it is one of the oldest dioceses in Germany and the third largest by area, covering approximately 30,000 km² of Lower Saxony across 17 deaconries, 119 parishes, and 416 churches. It serves a registered Catholic membership of approximately 523,000 to 550,000. The diocese's primary funding is the Kirchensteuer (church tax), an 8-9% surcharge on member income tax collected by the German state and redistributed to the diocese; this is supplemented by ancillary income from Catholic foundations, the Caritasverband für die Diözese Hildesheim e.V. social services subsidiary, and revenue from heritage and education assets.

Its core service offering is full-spectrum Catholic pastoral care: sacramental rites (baptism, first communion, confirmation, marriage, anointing), youth ministry, pilgrimage programs, marriage and family counseling (EFL), institutional chaplaincies in hospitals/prisons/schools/police, and Catholic education through diocesan schools and the Katholische Akademie. Operational units include the Bishop's General Vicariate (central administration), Bistumsarchiv, Dombibliothek Hildesheim, Dommuseum Hildesheim, LÜCHTENHOF education and conference center, Haus Wohldenberg youth center, and the Cathedral Music program with seven choir groups. The Hildesheim Cathedral (Mariendom St. Mariæ Himmelfahrt) and St. Michaelis Church have been UNESCO World Heritage Sites since 1985. Distribution is purely regional — the diocese does not operate outside Lower Saxony except for international mission partnerships (notably with the Church in Bolivia) and the multi-faith Braunschweiger Jakobsweg pilgrimage route.

The go-to-market model is community-led: parishioners are reached through the parish and deaconry network, specialized pastoral fields, institutional chaplaincies, and Caritas social services. Marketing and outreach use a multi-channel digital stack (TYPO3 CMS website, YouTube, Facebook, Instagram, SoundCloud, CleverReach email, Google Maps/Fonts), print (KirchenZeitung), radio (Hörfunkredaktion), and in-person events (pilgrimages, cathedral concerts, community gatherings). Pastoral services are provided free of charge; there is no commercial pricing. As of June 2026 the diocese is in sede vacante following the transfer of Bishop Dr. Heiner Wilmer SCJ to Münster, with Weihbischof Dr. Martin Marahrens serving as Diözesanadministrator.

• Erzbistum München und Freising: Major German archdiocese with comparable parish networks, Catholic schools, and a strong Kirchensteuer base. Functions as a similarly integrated pastoral, educational, and social-service organization with international partnership programs.
• Bistum Paderborn: Large Westphalian archdiocese with comparable parish scale, Catholic school network, Caritas operations, and historical heritage assets — operating the same dual role as ecclesiastical governance body and major social-service provider.

Others

• Caritasverband für die Diözese Hildesheim e.V. The Diocese's own Caritas affiliate, listed separately as a peer because it functions as a closely related but legally distinct social-services provider serving the same Lower Saxony catchment with family, senior, and migration support services.
