About this picture

The Diocese of Hildesheim ( Latin Dioecesis Hildesiensis ) is a Roman Catholic diocese in northern Germany. From its foundation in 815 to 1805 it belonged to the ecclesiastical province of Mainz and was then exempt . In 1824 the diocese was expanded considerably and in 1930 it became part of the Central German Church Province that was created at that time . Since 1995 the Diocese of Hildesheim has been part of the newly established North German Church Province . The seat of the bishop is the Hildesheim Cathedral in Hildesheim .


The area of ​​the diocese corresponds to the east of the Weser located portion of Lower Saxony and parts of the state of Bremen , namely Bremen-Nord ; thus the shares of the city of Bremen north of the Lesum , and Bremerhaven . It is one of the largest dioceses in Germany in terms of area, but almost exclusively comprises regions in which Catholics are a minority and therefore live in the diaspora . Only the dean's office in Untereichsfeld in the south of the diocese and the villages of the old “ (small) monastery ” in the Hildesheim area have a Catholic majority.



Around 800, Charlemagne built the mission diocese for Ostfalen in Elze , which at that time was called Aula Caesaris , or Aulica for short and is located about 19 km west of today's Hildesheim. The diocese was under the patronage of the Apostle Prince Peter and Paul , whose names the (old) Elzer Church still bears today. The diocese was re-founded in Hildesheim in 815 by Karl's son Ludwig the Pious and consecrated to Mary , the Mother of God (see also the founding legend ; Hildesheim Marian reliquary ).

Coat of arms of the Diocese of Hildesheim

At the time of its foundation, the Hildesheim diocese comprised the 17 Saxon districts of Astfala (around Hildesheim, Hanover, Peine, Braunschweig, Leine to Oker), Flutwidde (Dreieck Meinersen, Celle, Burgdorf), Liergau (Braunschweig Wolfenbüttel south-west of the Oker), Saltgau (around Salzgitter-Bad), Wenzigau (Dreieck Bilderlahe, Liebenburg, Lutter am Barenberge), Ambergau (around Bockenem to Woldenberg and Seesen), Flenithigau (Gandersheim, Winzenburg), Aringo (Gronau to Alfeld), Tilithigau (Viereck Lauenstein, Lauenau, Bad Münder, Hameln), Valingau (Gronau, Poppenburg, Elze), Gudingau (around Eime between Saale and Leine), Scotelingau (north of Steuerwald), Muldese (around Isernhagen), Marstemgau (Calenberg, Spiegelburg, Hanover, Deister), Osterwalde (Between Erse and Aller), Helingau (around Gifhorn) and Muthiwide (confluence of Aller and Oker).

Under Bishop Altfrid , the first stone cathedral was built in 852–872 , the layout of which has remained unchanged to this day. The diocese of Hildesheim attained its greatest importance at the time of the Saxon emperors through the holy bishops Bernward (993-1022) and Godehard (1022-1038). Architectural and art treasures from this period shape the image of the city to this day.


From 1235 to 1802 the Bishop of Hildesheim was also imperial prince. Its territory, the Hildesheim monastery , was smaller than the diocese. From 1500 it belonged to the Lower Saxony Empire . As a result of the Hildesheim collegiate feud (1519-1523), the area was reduced by half.

The traditional coat of arms of the diocese shows a shield split in gold and red. The diocese colors were also adopted by the city of Hildesheim after 1300 in a modified form.

Reformation time

The council and citizenship of the city of Hildesheim as well as the Guelph territories, which made up the largest part of the Hildesheim diocesan area, went over to the Lutheran creed in the 16th century . Only the cathedral and several monastery churches in the city as well as the villages of the monastery area after 1523, the so-called monastery villages Algermissen , Bettmar , Borsum , Detfurth , Diekholzen , Dinklar , Förste , Giesen , Harsum , Ottbergen , Moritzberg , Himmelsthür and others, remained Catholic. Of the northern German bishops' seats, apart from Osnabrück, only Hildesheim continued to exist without interruption.

The ecclesiastical diocesan borders from 815 were not changed until 1823, even when the neighboring bishoprics of Minden , Verden and Halberstadt had perished and their diocesan areas belonged to the Nordic Missions , later to the Apostolic Vicariate of the North .

Consequences of the Thirty Years War

In the course of the territorial reorganization of the empire as a result of the Thirty Years' War , the prince-bishopric of Hildesheim was re-established with the "Recess of Goslar" in 1643 within the borders before 1523. The now Lutheran areas, which now belonged again to the rule of the Hildesheim Chair, were not recatholicized . Only individual parishes (official parishes ), monasteries and church service stations were newly created ( Bolzum , Gronau , Lamspringe , Peine , Poppenburg , Ringelheim , Ruthe , Westfeld and others).

18th and 19th centuries

In the 18th century , the small prince-bishopric of Hildesheim maintained itself through personal unions with the more powerful spiritual states of northwest Germany. Prince-Bishop Clemens August from the House of Wittelsbach ruled Cologne , Münster , Paderborn , Osnabrück and Hildesheim at the same time for almost four decades .

After Hanover's annexation of some of the former ecclesiastical principalities, the Kingdom of Hanover began negotiations with the Holy See for a concordat in 1816 , but these finally failed in 1821. Thereupon Hanover sought - following the Prussian example ( De salute animarum ) - only one circumscription bull . According to the treaty between Hanover and Rome of 1824, the Pope then issued the corresponding bull Impensa Romanorum Pontificum , which redrew the borders of the Hanoverian dioceses of Hildesheim and Osnabrück so that all state territory belonged to one of the two dioceses. However, the chair in Osnabrück initially remained vacant and was also looked after by Hildesheim by a vicar general and auxiliary bishop, as Rome and Hanover had remained divided over the financing of this diocese and had postponed the clarification until later. Hanover also ensured that both dioceses did not become suffragans of a foreign metropolitan, but that Hildesheim remained exempt and Osnabrück became one.

Since then, Hildesheim's diocesan area has included, with a few deviations, the part of Hanover east of the Weser or the state of Lower Saxony , thus also the former Electoral Mainz , Catholic lower area with Duderstadt and the former diocesan areas of Bremen, which until then belonged to the Nordic Mission, excluding the northern Elbe cities of Hamburg, Holstein and Dithmarschen, Mindens east of the Weser and Verdens without the Altmark.

20th century

The number of diocesans rose sharply due to the influx of East German expellees after the Second World War (about 646,000 on December 31, 2007). These came in particular from Silesia and the East Prussian Warmia , but also from Czechoslovakia . New parishes and churches were built for them in all parts of the diocese. These new churches were often built in the simple style of the 1950s and 1960s, so that they could have been demolished quickly if necessary, since it was initially assumed that the expellees would one day return to the formerly German eastern territories and thus the number of parishioners as well would fall off again quickly as they had risen after the war. In the course of the savings after the decline in church tax revenues at the turn of the millennium, the closure of many churches is also planned. Former displaced persons and their descendants, immigrants from West and South Germany , late repatriates from Poland and the former Soviet Union as well as immigrants from Italy , Spain , Portugal and Croatia represent large groups in the communities that shape everyday life.

In 1930 the area of the Grafschaft Schaumburg district came from the diocese of Fulda , and in 1965 the area of ​​the former state of Schaumburg-Lippe from the diocese of Osnabrück to the diocese of Hildesheim. Together they formed the Bückeburg dean's office, which was merged with the Hameln-Holzminden dean's office on September 1, 2012 to form the new Weser Uplands dean's office. Also in 1965, Cuxhaven , which had already changed state in 1937 through the swap of territory from Hamburg to the province of Hanover, was reclassified from the Diocese of Osnabrück to the Diocese of Hildesheim.

During the existence of the GDR , six churches on the territory of the GDR belonged to the diocese of Hildesheim, but were subordinate to apostolic administrators in the GDR: the church in Neuhaus to the administrator in Schwerin, the churches in Blankenburg , Elbingerode , Hasselfelde and Hesse to the administrator in Magdeburg and the church in Lower Saxony to the administrator of Erfurt and Meiningen. The church in Neuhaus still belongs to the diocese of Hildesheim today, the other churches today belong to the dioceses of Magdeburg and Erfurt, which have existed since July 8, 1994 .

Since the Archdiocese of Hamburg was founded on January 7, 1995, the Diocese of Hildesheim has belonged to the Hamburg Church Province (previously it was the suffragan of the Archdiocese of Paderborn ). The parishes of Harburg and Wilhelmsburg , located south of the Elbe and which have belonged to the state of Hamburg since 1937, were ceded to the neighboring archdiocese.

21st century

Josef Homeyer had been Bishop of Hildesheim since November 13, 1983 . After Pope John Paul II granted his resignation on his 75th birthday, the longest serving Auxiliary Bishop Hans-Georg Koitz took over the management of the diocese in August 2004 and was elected diocesan administrator by the cathedral chapter . On November 29, 2005, the then Auxiliary Bishop of Cologne, Norbert Trelle, was appointed the 70th Bishop of Hildesheim. The official inauguration ( taking possession of the Cathedra ) was on February 11, 2006 in Hildesheim Cathedral.

Auxiliary Bishop Koitz retired on May 1, 2010 after his 75th birthday. Pope Benedict XVI appointed his successor. on December 4, 2010 the then head of the HR / Pastoral Care Department in the Diocese of Hildesheim, Heinz-Günter Bongartz . The episcopal ordination of Heinz-Günter Bongartz was on February 26, 2011 in the Hildesheim Basilica of St. Godehard. Nikolaus Schwerdtfeger has held the office of second auxiliary bishop since 1995 . Heinz-Günter Bongartz has also been Vicar General since October 1, 2016, appointed by Bishop Norbert Trelle and reappointed by Bishop Heiner Wilmer on September 1, 2018.

Until his retirement, Bishop Josef Homeyer invited the young people of the diocese to Christian Mass for over 20 years . This tradition is unique in its form. Bishop Norbert Trelle continues this tradition after taking office.

The resignation that Bishop Norbert Trelle submitted on his 75th birthday, September 5, 2017, was accepted by Pope Francis with effect from September 9, 2017. On September 11, Auxiliary Bishop Nikolaus Schwerdtfeger was elected diocesan administrator. On April 6, 2018, Pope Francis appointed the superior general of the Dehonians , Heiner Wilmer , as the 71st Bishop of Hildesheim. He was ordained bishop on September 1, 2018 and took up his office as Bishop of Hildesheim.

Around 2010 the Diocese of Hildesheim was in a process of reorientation. The pan-German phenomenon of “evaporation of faith” is exacerbated in the diaspora situation. For a long time the parishes were shaped by displaced people from Catholic backgrounds, most of whom came from Silesia, Warmia or Czechoslovakia. They were followed by a second and third generation who did not get to know the Catholic customs of the former family areas of origin. In Eichsfeld and the abbey villages, too, the dominant force of the festival calendar and the Catholic associations is waning. In recent times repatriates from Poland and the former Soviet Union and their relatives have made up a large part of the communities. In addition, there are many families who have immigrated from Catholic regions in Germany and from southern Europe.

In the statistics of church attendants, Hildesheim and here again the dean's office in Verden, with eleven percent, bring up the rear among the German dioceses. An important reason for the decline in church membership is an imbalance between baptisms and funerals in favor of funerals, with the average age continuing to rise.

The diocese management is reacting to this development by amalgamating parishes, reducing staff and, in the medium term, also by closing churches . At the same time, through the promotion of “small spiritual communities” and the subject of the laity, a renewal and intensification of church and spiritual life is sought.

Economic constraints due to a decline in church tax revenues, a shortage of priests and a decline in the number of practicing Catholics mean that on the one hand congregations are merged into larger parishes, but on the other hand churches are also closed . The buildings are being converted into living space, given to other religious communities or demolished.

In January 2008 the diocese published a provisional administrative draft with a categorization of the churches in the diocese. 216 churches are currently not available; in the case of other 56 churches, their pastoral needs are to be reviewed again in the medium term. The remaining 166 churches no longer receive any money from the diocese. Of these, 80 churches are to be closed from 2009 onwards. For the other 86 churches, the parishes alone would have to raise the financial means to maintain them. As long as they manage this, the church will remain.


Heiner Wilmer has been Bishop of Hildesheim since September 2018

Key points 2020

Due to the decrease in the number of Catholics and the shortage of priests in the diocese of Hildesheim as well as the increasingly deteriorating financial situation of the diocese, the concept "Key Points 2020" was developed in 2003, which in addition to direct savings (e.g. by closing facilities) also achieved a reduction through amalgamation the number of municipalities from 350 at that time to 124 in 2014. The implementation of the concept began in 2004 with the merging of 49 parishes into 19 larger parishes. Overall, the diocese's expenditures should only amount to around 2/3 of the 2003 budget annually by 2020.

Since 2006, as with other German dioceses and Protestant regional churches, the income of the spouse of different faiths has been included in the calculation of the church tax (special church money in marriage of different faiths). This resulted in an increased number of people leaving the church.

German Bishops' Conference

On the occasion of the diocese anniversary, the spring general assembly of the German Bishops' Conference took place in the Diocese of Hildesheim for the first time from February 23 to 26, 2015 . Topics were the Synod of Bishops in October 2015, migration, church asylum and refugees as well as the training of priests, as well as the inter-diocesan discussion process and the ecumenical social initiative. The exchange about the difficult situation in Ukraine was particularly important for the world church. Guests were in addition to the Apostolic Nuncio in Germany, Archbishop Dr. Nikola Eterović , Archbishop Antonio Javellana Ledesma SJ ( Archdiocese of Cagayan de Oro , Philippines) and Bishop Crispin Barrete Varquez ( Diocese of Borongan , Philippines).


Historical development

The Diocese of Hildesheim consisted of around 41 archdeaconates in the 12th century . it was thus fragmented compared to Mainz (22), Cologne (7), Trier (5), Worms (10) or Würzburg (12). A amalgamation of archdeaconates was in the making, as they were each loaned to a canon and their number was at times greater than the number of canons at the chapter of the cathedral . When it turned out that the canons did not always comply with the residence obligation required for the office, it was decided to merge. The first documented example is the union of Hildesheim and Rheden under Rainald von Dassel . This reorganization gradually established itself in the entire diocese. Officials were used for administration. Ultimately, twelve archdeaconates crystallized:

The organizational structure composed in archdeaconates actually collapsed in the middle of the 16th century. The main reasons were the Hildesheim collegiate feud and the Reformation . In the course of general secularization, the Prussian government also formally ordered the archdeaconates to be called in in 1805.


Today the church and pastoral tasks of the diocese are divided between 17 regional deaneries . Their deans are responsible to the bishop. The vicar general directs all other administrative tasks.

Pilgrimage sites

The pilgrimage sites are all in the south of the diocese in the area of ​​the cities of Hildesheim and Göttingen.
