The series "Controversia et Confessio" documents the inner-Protestant disputes after the Interim of 1548. The nine-volume edition is based on the treated theological-historically relevant topics and offers those texts that were of central importance for the development of the denominations. Behind the controversy was the dispute about the legacy of the Wittenberg Reformation carried out by Luther and Melanchthon, as well as the question of the relationship between religion and politics, the search for authorities providing orientation and the struggle for theological authenticity with a simultaneous pluralization of positions. This tenth volume concludes the edition with a complete index.
