Two areas in which the approach to theology has undergone an obvious change in the past few years are those of the Incarnation and Original Sin. In the first instance, the change has resulted in an increased emphasis on Christ's humanity; in the second, Original Sin has come to be regarded more as a situation or condition of humanity than as a ""sin"" committed by Adam and Eve and passed on, willy nilly, to all men. De Rosa's purpose in selecting these two subjects for discussion is to illustrate the potential of, and the excitement in, a theology which has only recently become more concerned with relevancy than with intellectual gymnastics. That he succeeds so well is a tribute not only to the importance of the developments which he synopsizes and explains, but also to his skill as both theologian and writer. The book is a work of theology, albeit a popularization in the best sense of the term; as such, it will hardly sell extensively; but it should be recommended, for the spirit which it illustrates, to all students of theology as well as to the interested Catholic layman.
