In this brief but thorough exegetical study Dr. Haag dispenses with one of the enduring myths of Christianity, the concept of ""original sin"" as an individual rather than a cosmic state. By the use of sound logic and a sound methodology, he goes considerably beyond a simple negative answer to the question of the title and draws corollary conclusions which are of more than passing interest. Among them: whether mankind originated in monogenism or polygenism is a wholly non-theological concern; no man is born ""in sin""; baptism does not remove ""original sin,"" but makes man a member of Christ; there is, in fact, no such thing as ""original sin"" in the sense in which that term is generally understood. Haag's accomplishment is not merely that he jettisons a bit of pre-Copernican mythology that has long annoyed both theologians and laymen, but also that he does so on the soundest theological premise of them all, i.e., Sacred Scripture. This is a far cry from the we-don't-want-it-therefore-it-doesn't-exist school of demythologizing which seems in the ascendancy today, and therefore the book should have an enduring as well as a strong impact upon the current re-thinking of the doctrinal bases of Christianity.
