The tradition that the third gospel was written by Luke the doctor dies hard. We may realize that the ‘Luke the doctor’ of Colossians 4, 14 is not necessarily the same Luke as the one to whom the gospel is attributed (just as there is no shadow of an indication that the Mark of the second gospel is any of the Marks mentioned in the Acts and the Epistles). We may know that all attempts to show that the author of the third gospel used medical language collapse, simply because there was no such thing as technical medical language in those days. Yet there remains a sympathy with human suffering and appreciation of the many-sidedness of men’s characters, a power to make a penetrating yet kindly assessment which is often —rightly or wrongly—associated with the medical man, the Dr Camerons or even the Dr Findlays of this world. But Luke is no country doctor from the highlands or the valleys, and it is because of this that his special preoccupation with rich and poor is especially significant to Christians of an affluent society brought face to face with poverty.

Luke stands out among the other New Testament writers by a certain grace and dignity. The gospel of Mark, on which a large part of both Matthew’s and Luke’s gospels is based, is undisguisedly Kleinliteratur, stories told uncomplicatedly in simple, popular form, without literary pretension; he writes the sort of Greek which was probably spoken by the lower classes in the cities of the Roman empire.
