This study provides an in-depth analysis of the relationship between modernity and Christianity. The author argues that the notion of revelation is eminently reasonable and indissolubly connected with being and reality. He takes Jaspers' philosophy of religion as representative of the 'classical' modern critique and gives it its due. He then takes a step backward, so to speak, and by means of a consideration of the history of ideas, seeks to rehabilitate the Christian understanding of revelation. To do this, he draws upon Schelling's remarkable philosophy of revelation and Baader's much less familiar speculative dogmatics. However, this study is much more than a profound philosophical and theological account of the thought of Jaspers, Schelling and Baader. It is above all an eloquent defence of the plausibility and intelligibility of what Christians have always believed. In fact, the author makes a compelling case for the claim that revelation is 'that without which Christianity cannot be thought'.
