IF THE MAIN topic of chapters 1 and 2 was the arrival of the Son of God in our world, it is easy to see that the next main topic is going to be his official introduction to the world of men and the beginning of his public ministry. The question arises, however, whether Luke intends us to read all the following chapters in one unbroken stream, or whether here, too, as in Stage 1, he has grouped his narratives so that we might the better see their significance.
