Book excerpt: The second volume of the eminent Christian philosopher’s magnum opus, in which he explores humanity’s quest for Christ. Paul Tillich’s Systemic Philosophy is the most comprehensive and definitive presentation of his groundbreaking theological message: his “method of correlation”, which finds the answers to humanity’s most urgent existential dilemmas in the principles of Christian revelation. In volume two of this three-volume work, Tillich comes to grips with the central idea of his system—the doctrine of the Christ. Here, Tillich describes the human predicament as the state of “estrangement” from ourselves, from our world, and from the divine Ground of Being. This situation drives us to the quest for a new state of things, in which reconciliation and reunion conquer estrangement. This is the quest for the Christ.
