First published in the US in 1956, in these lectures Professor Tillich analyzes the development of Christian theology. This classic is for theology students and others interested in the range of Church history and teaching. In Paul Tillich has accomplished the supremely difficult feat of creating a work at once brilliantly authoritative and comprehensive, while remaining clear and uncluttered by scholarly annotation and debate. Originally delivered as lectures at the Union Theological Seminary and at the Divinity School of the University of Chicago, Professor Tillich guides the reader through the fascinating history of Christian thought with a confidence and clarity of presentation only a great scholar and teacher possesses.
