Can Christians affirm their belief uneqivocally without denying the beliefs of others? They can, this book holds, by claiming that Christian revelation is both reasonable and faithful to tradition, but not necessarily infallible or exclusively definitive. To the Christian, in Dr. Ketcham's words: "It is in the life, death, and Resurrection of Christ that God presently reveals Himself; this is what is meant by the term Christ-event. . . . The Church is therefore the community of those whose identity has been and is being influenced by their encounter with God in this event." Thus the Christian "must participate in the suffering and conflict of this world, not out of superiority of insight but because of an integrity of dedication." Dr. Ketcham believes that current changes in the thinking and expression of the 19th and early 20th centuries are not matters of style or vogue. Rather, they are changes having to do with our understanding of the very nature of reality. No aspect or expression of life is left unaffected least of all our understanding of the person and work of Jesus the Christ. Therefore "the purpose of this book is to provide an alternative to the traditional doctrine of the incarnation, an alternative which will do justice to the witness of Scripture, to the history of faith, and to the insights of a phenomenological ontology. "Beginning with the ontology implicit in Buber's I and Thou and Heidegger's Being and Time and responsive to the insights of Husserl's phenomenology and Kierkagaard's existentialism, Dr. Ketcham takes a more radical position than most contemporary theologians. His purpose is to make a contribution toward the revitalization and unification of the Church: "The mission of the Church is to achieve community, a oneness through the Christ-event, so that every man may affirm with freedom his authentic being with God and with his fellow man.""
