This thesis examines and evaluates F.C. Baur's philosophical and theological ideas as they relate to the writing of Church history and historical theology. The study is undertaken within the context of the problem of the relation between faith and history, which can be stated in more relevant categories for Church historiography as the problem of the relation between subject (faith) and object (history), and proposes that Baur's thought on this problem can be useful for the modern faith/history debate, and especially for the consideration of writing Church history.
