Today there are two pastoral units (German "Seelsorgeeinheiten") operating in the territory of Horb am Neckar: "Seelsorgeeinheit Steinachtal" includes the parishes in Altheim, Grünmettstetten, Bittelbronn, Untertalheim and Obertalheim; "Seelsorgeeinheit Horb" includes parishes in Horb itself, Ihlingen and Isenburg, Bildechingen, Mühlen, Rexingen and Nordstetten, Ahldorf and Mühringen, along with Wiesenstetten, which belongs to the municipality of Empfingen. Parishes in Betra, Dettensee, Dettingen, Dettlingen and Dießen have actually belonged to the Archdiocese of Freiburg (Deanery of Zollern) since 1827, due to those communities' former inclusion in the Principality of Hohenzollern-Sigmaringen.
