The city was part of the Diocese of Konstanz until 1821.
That same year, Freiburg became an episcopal see of the Roman Catholic Archdiocese of Freiburg.
Due to a dispute between the government of Baden and the Holy See, the archbishop officially took office in 1827.

The borders of the archdiocese correspond with the borders of the former province of Baden and the former Margraviate of Hohenzollern.

The Archbishop of Freiburg holds the title of metropolitan and the German headquarters of the Caritas International is in Freiburg.

Saint George (the flag of Freiburg has the cross of George), Lambert of Maastricht and the catacomb saint, Alexander, are the patron saints of Freiburg.
Many works of art depicting these saints are in the Freiburg Minster, on the Minster square, just as in the museums and archives of the city, including some by Hans Baldung Grien, Hans Holbein the Younger and Gregorius Sickinger.

In 1805, with the attack of Breisgau on the Grand Duchy of Baden by a Catholic ruler, many Protestants moved into the city.
Since 2007, any Protestants who are not part of a ‘free church’ belong to the newly founded deanery of Freiburg as part of the parish of Südbaden which in itself is a part of the Landeskirche Baden.

The seat of the Evangelical Lutheran Church in Baden, a free Lutheran church, is situated in Freiburg.
There are multiple other free Protestant churches: e.g. the Calvary Chapel or Chrischona International.

The Catholic Church of St. Maria Schutz has been made available for Masses by Greek, Serbian, Russian and Rumanian Orthodox congregations.

Judaism
Jews are said to have lived in the city before 1230, but it was only after 1230 that they supposedly founded an official community in the Webergasse (a small street within the city center).
The counts of Freiburg bought the lucrative Schutzjude, which means that all personal information on Jews living in Freiburg was directly sent to Konrad II and his co-reigning son Friedrich.
The two issued a comprising letter promising safety and liberty to all local Jews on 12 October 1338.
It lost all value shortly after, however, on 1 January 1349.
Even though the plague had not yet broken out in the city, Jews were accused of having spread it and taken into custody.
All Jewish people with the exception of pregnant women were burned alive on 31 January 1349.
The remaining children were forced to be baptized.
This pogrom left Jews very hesitant to settle in the city again.

Middle High German dialect: “daz dekein Jude ze Friburg niemmerme sin sol”[27].
This was also officially reaffirmed by King Sigismund with a ban for life (orig.
German: “Ewige Vertreibung”) in 1424.

They subsequently founded a Jewish community in 1836.

At the Kristallnacht in 1938, the synagogue, built in 1870, was set afire.
Numerous shops and apartments of Jewish citizens of Freiburg were devastated and plundered by National Socialists without the intervention of police or fire department.
