This study of St. Luke's theology is, by its approach to the problems, for the most part not dependent on any particular literary theories about St. Luke's Gospel and the Acts of the Apostles, for it is concerned with the whole of Luke's writings as they stand. If these form a self-contained scheme, then for our purpose literary critical analysis is only of secondary importance. Nevertheless, in this secondary sense it is important, and is therefore not to be despised. We must make it plain, however, that our aim is to elucidate Luke's work in its present form, not to equire into possible sources or into the historical facts which provide the material.
