The Bach Choir and Bach Collegium are supported by the registered society, “Bach-Chor an der Kaiser-Wilhelm-Gedächtnis-Kirche e.V.” The society was founded in 1963 after the cycle of cantatas was consolidated at the Kaiser Wilhelm Memorial Church; it replaced the “Arbeitskreis für Kantate-Gottesdienste” (Working Committee for Cantata Worship Services) and is entered in the association register of the local court of Charlottenburg under number VR 3471 B. The society‘s purpose, according to its charter, is the artistic cultivation and promotion of musica sacra, notably the sacred works composed by Johann Sebastian Bach. The purpose of the charter is realised in particular by the Bach Choir performing church music and by the Bach Collegium accompanying the musical performances of the Bach Choir as a chamber orchestra. The Bach Choir regards its practice as a church service.
