Confession statistics
At the end of 2019, of the 168,876 residents, 49.0% were Roman Catholic, 12.5% were Protestant, and 38.5% belonged to another religious community or no religious community. In the previous year 2018, of the 168,426 residents, 50.2% were Catholic, 12.8% were Protestant, and 37.1% belonged to another religious community or no religious community. In 2017, 51.4% of Regensburg's population was Catholic, 13.1% was Protestant, and 35.5% belonged to other or no religious community. In 1970, 82.4% of the population had been Catholic and 14.5% Protestant. The term "Protestant" includes the Lutheran, Reformed and Uniate confessions, but not the free churches. Since 1950 (when 84.3% of the population were Catholic), the proportion of Catholics in the total population has been steadily decreasing.
Christianity
In 739, Saint Boniface founded the bishopric of Regensburg. In the following period, numerous monasteries were founded. Regensburg was in close cultural exchange with Cashel, Ireland. Clergymen were trained there who later came to Regensburg. The diocese of Regensburg was first subordinated to the archdiocese of Mainz, later to the archdiocese of Salzburg. Even though due to the accumulation of benefices Regensburg often lacked the personal presence of its chief shepherd, since the canonical erection of the bishopric there has been a succession of Regensburg bishops, only slightly interrupted by the modalities of appointment, up to the present day.
After the introduction of the Reformation in October 1542 and the first public communion on October 15, 1542 in the Neupfarrkirche, the city council and the citizens had converted to Protestantism, but the Catholic imperial estates remained in the city of Regensburg, as did the Catholic bishop's see and the imperial-free monasteries of Obermünster and Niedermünster and the imperial-free monastery of St. Emmeran, which did not belong to the territory of the imperial city itself. The Catholic confession continued to be represented in the city and became the predominant confession after 1810 due to numerous immigrants. The mixture of confessions had given Regensburg a special position in the empire at an early stage and, in addition to its proximity to imperial Vienna, was also a reason why the Perpetual Diet took its seat in Regensburg. The city offered a territory in the empire where both confessions could meet peacefully.
Until the Imperial Deputation in 1803, the office of the Imperial Chancellor was tied to the Archbishop's See of Mainz. In 1803, this was Carl Theodor Anton Maria Reichsfreiherr von Dalberg. With the Reichsdeputationshauptschluss the rights of Mainz were transferred to Regensburg, and Dalberg became Archbishop of Regensburg, which he remained until his death in 1817. In 1817/1821 the diocese of Regensburg was newly circumscribed and placed under the ecclesiastical province of Munich and Freising. The diocese of Regensburg is the largest Bavarian diocese in terms of area, covering 14,665 square kilometres, and is made up of 33 deaneries. The 24 parishes and 4 other pastoral offices of the city of Regensburg belong within the diocese to the deanery of Regensburg, which forms the region of Regensburg with the deaneries of Laaber, Alteglofsheim, Donaustauf and Regenstauf.
After the introduction of the Reformation, the Protestant congregations were led by a superintendent. A consistory existed as church administration authority. After the transfer to Bavaria in 1810, the congregations became part of the Evangelical Lutheran Church in Bavaria. Within this regional church, the seven Regensburg congregations belong to the Regensburg deanery in the church district of the same name.
In the area of the free churches, there are congregations of the Adventists, the Baptists, the Mennonites (since 1820) and the Methodists as well as a Pentecostal Free Christian Church and a Free Evangelical Church in Regensburg today.
In addition, there is an Old Catholic parish in Regensburg. The Russian Orthodox parish uses the Maria Schutz Church in the city park. The Romanian Orthodox parish of St. Trinity uses the monastery church of St. Matthias in Ostengasse. In its monk's choir behind the high altar a chapel was established in 1974 by the Eastern Church Institute Regensburg, which is used today by the Serbian Orthodox parish.
The Church of Jesus Christ of Latter-day Saints is represented by a congregation in Regensburg.
During his six-day pastoral tour of Bavaria in 2006, Pope Benedict XVI spent three days in Regensburg. He celebrated Holy Mass on the Islinger Feld, located on the southern outskirts of the city, together with about 230,000 people. In addition, he gave a lecture at the university that was subsequently criticized by the Islamic side and celebrated an ecumenical vespers in the cathedral with high representatives of the Protestant and Orthodox Churches.
From 28 May to 1 June 2014, the 99th German Catholics' Day took place in Regensburg. This was the third Katholikentag in Regensburg, the first was held in 1849 and the second in 1904.
Judaism
→ Main article: Judaism in Regensburg
Regensburg was the first Jewish community in Bavaria and one of the most important in Europe in the Middle Ages. The earliest documented mention of a Jew in Regensburg dates from 981. In the following centuries, the community flourished and produced some of the most famous contemporary scribes and lyricists such as Isak ben Mordechai, Efraim ben Isaak (Efraim the Great from Regensburg) and Jehuda ben Samuel he-Chasid (Jehuda the Pious). The Jewish quarter was located on what is now Neupfarrplatz. In 1519 the synagogue was destroyed and the Jews were expelled. From 1669 Jews again lived in the city. Between 1861 and 1871 the community grew from 150 to 430 members. A new synagogue was built in 1912.
The eventful history of the Jewish community in Regensburg ended for the time being with the destruction of the synagogue on the night of the pogroms in 1938 and the deportation and murder of Regensburg's Jews during the Second World War. The approximately 400 Jews in Regensburg were dispossessed, robbed and deported. About 250 were murdered.
After the end of the war in 1945 Regensburg took in about 3,500 Jews who had been liberated from the Flossenbürg concentration camp. In addition, there were Jews with unclear nationality who had fled from camps in Eastern Europe to the Bavarian US occupation zone and were therefore counted among the large group of so-called displaced persons. They were accommodated in the Ganghofer Settlement. Most of them emigrated to the USA or Israel, so that in 1953 Regensburg counted only about 400 Jews. At the beginning of the 1990s there were just 60. Since the collapse of the Soviet Union the number has risen again to about 400.
During excavations at Neupfarrplatz, remains of the synagogue were rediscovered in 1995. The city set up an information centre there, the document Neupfarrplatz. It provides information underground about the eventful history of Neupfarrplatz: Jewish ghetto and religious centre of international importance, expulsion of Jews, Catholic pilgrimage church Zur Schönen Maria, Protestant Neupfarrkirche as the mother church of Austrian and south-eastern European Protestantism. The floor plan of the former synagogue is traced by a walk-on floor relief of white concrete designed by Israeli artist Dani Karavan, which was inaugurated on July 13, 2005. The Jewish Community Center with a synagogue, inaugurated in 2019, stands on the site of the previous building destroyed in the Pogrom Night a few 100 meters east of Neupfarrplatz in the street "Am Brixener Hof". Jewish cemeteries are located in Schillerstraße west of the city park and in a section of the municipal cemetery on the Dreifaltigkeitsberg.
Islam
The number of Muslims registered as living in Regensburg is probably between 4,000 and 5,000, of whom a good half are probably of Turkish descent. From the remaining countries of origin of Muslim immigrants, which range from Morocco to Pakistan and Indonesia, as in many other large German cities, a larger group of Tunisians, who have lived in the city since 1969, and the Iraqis, who became residents especially in the years after 1995, are worth mentioning. In addition to two Turkish mosque associations of the DITIB (Merkez Mosque, Lindnergasse, founded in 1978, later DITIB Association) and the VIKZ (Adolf-Schmetzer-Strasse) there is an "Albanian-Islamic Cultural Centre" (Alte Straubinger Strasse), a branch of the Ahmadiyya (Von-Donle-Straße) and two Arab associations, the "Islamic-Arabic Cultural Association" (As-Siddiq, Walderdorffstraße) and the "Islamic-Arabic Cultural Centre" (Al-Rahman-Mosque/Masjid Arrahman).
After moving out of its former premises in Hemauerstraße, the latter built a large community centre on Alte Straubinger Straße in 2009.
Muslim cemeteries are located in a section of the municipal cemetery on the Dreifaltigkeitsberg as well as in the village of Kareth, which lies to the north of Regensburg.
Buddhism
In 1978 a Buddhist meditation group was established in Regensburg under the guidance of Lama Ole Nydahl. Subsequently, the Buddhist Center Regensburg was founded, since 1999 in the historic building Brixener Hof, currently the largest Buddhist group in the city. The Buddhist Centre is organised in the non-profit association Buddhist Centres Bavaria of the Karma Kagyu Lineage e. V. under the Buddhist umbrella organisation Diamantweg (BDD) e. V.. In addition to the Diamond Way Centre, several other Buddhist groups are active in Regensburg, such as the Regensburg Buddhist Meditation Group, Zen Buddhists and Won Buddhists.
