THE study of "Eschatology in Luke," by E. Earle Ellis rates attention for at least four reasons. Two have to do with matters set forth in the very title: the function of "eschatology," and "Luke" as a reflection of the editorial craftsmanship and the theology of the author of Luke-Acts. A third is the role Luke's eschatology plays in early Christian history and in what has been dubbed "early catholicism." Finally there is the fact that Professor Ellis, as an articulate spokesman for a salvation-history perspective in New Testament scholarship, seeks to pose an alternative to what Hans Conzelmann, Helmut Flender, and others have done with Luke and his eschatology.
