Text in German. The focus of the investigation is the cultural dimension of religion. Subject design, piety practice and coping with life of women, men and children of the pietistic and academically educated middle class of Altwuerttemberg as well as their communicative group culture and tradition are presented. The new and individual culture of this bourgeoisie can be summed up as the "spiritualization of everyday life". Astonishingly many pietistic-bourgeois cultural techniques refer in a secularized form to the bourgeois culture of modernity. The research period begins after the Thirty Years' War with the emergence of pietistic piety and leads over the 18th century to the practice of pietistic-bourgeois piety up to the middle of the 19th century.
