"Paul Tillich sees the end of the Protestant era approaching--with the rise of technology and dehumanization--yet he argues for the continuing validity of Protestant principles in the affairs of mankind. Even if the modern world is witnessing the decline and fall of Protestantism's greatest historical age, a new spiritual and social reformation can take place, using the original prophetic and creative power that lies at the heart of Protestant thinking and action... Paul Tillich calls for the shaping of a new philosophy of history and culture to face the disasters of secularism and calls for a realization that Protestantism is not limited to any particular historical period but can always find new forms of expression to serve church and society."--From book jacket.
