The overwhelming majority in the village is Evangelical, 507 of 640 inhabitants. Seventy-seven inhabitants, however, are Catholic. Adhering to other faiths are five villagers, while 34 belong to no religious group and 15 refused to answer the question. The council is made up of 12 council members, who were elected by majority vote at the municipal election held on 7 June 2009, and the honorary mayor as chairman. Erdesbach's mayor is Ralf Lukas, and his deputies are Helmut Fehrentz and Joachim May. The German blazon reads: "Von schwarz und blau durch einen silbernen Wellenbalken geteilt, oben ein rot gekrönter und rot bewehrter goldener Löwe, unten eine silberne mit roten Steinen belegte Mitra mit seitlich abflatternden Bändern." The municipality's arms might in English heraldic language be described thus: A fess wavy argent between sable a demilion Or armed, langued and crowned gules, and azure a mitre of the first garnished of the fourth. The charge below the wavy fess, a mitre, refers to Erdesbach's former feudal landlord, the Bishopric of Reims, under whose sway lay the "Remigiusland". The lion is drawn from the arms borne by the Wittelsbachs, the ruling house of the Duchy of Palatinate-Zweibrücken and later the Kingdom of Bavaria, to which Erdesbach once also belonged. The wavy fess stands for the river Glan. The following are listed buildings or sites in Rhineland-Palatinate’s Directory of Cultural Monuments:  Until 1966, the more than 500-year-old "Gallusmarkt" (“Saint Gall’s Market”) was celebrated together with the bigger neighbouring municipality of Ulmet in the middle of the week as a kermis (church consecration festival). Its dates were set at the first Tuesday and Wednesday after Saint Gall's Day (16 October). In 1966, following the citizens’ wishes, and after municipal council had voted unanimously on the question, the kermis date was moved from late autumn to summer, namely the first weekend in August. The raising of the Maypole on May Day is a job that was taken over years ago by the young men of the volunteer fire brigade.
