It is not surprising, then, that there should be dual or even triple ascriptions of authorship for various portions of the Scriptures, and Luke's writings have on this score suffered as much or more even than others, with the possible exception of Moses. It is now definitely settled, however, that the similarities of style between the Acts and the third gospel are too great for them to have come from two different minds. This is especially true, as pointed out by Harnack, in all that regards the use of medical terms. The writer of the Acts and the writer of the third gospel knew Greek from the standpoint of the physician of that time. Each used terms that we find nowhere else in Greek literature except among medical writers. What is thus true for one critical attack on Luke's reputation is also true in another phase of recent higher criticism. It has been said that certain portions of the Acts which are called the "we" portions because the narration changes in them from the third to the first person were to be attributed to another writer than the one who wrote the narrative portions. Here, once more, the test of the medical words employed has decided the case for Luke's sole authorship. It is evidently an excellent thing to be able to use medical terms properly if one wants to be recognized with certainty later on in history for just what one's business was. It has certainly saved the situation for St. Luke, though there may be some doubt as to the real force of objections thus easily overthrown. It is rather interesting to realize that many scholars of the present generation had allowed themselves to be led away by the German higher criticism from the old tradition with regard to Luke as a physician and now will doubtless be led back to former views by the leader of German biblical critics. It shows how much more distant things may influence certain people than those nearer home--how the hills are green far away. Harnack confesses that the best book ever written on the subject of Luke as a physician, the one that has proved of most value to him, and that he still recommends everyone to read, was originally written in English. It is Hobart's "Medical Language of St. Luke,"[34] written more than a quarter of a century before Harnack. The Germans generally had rather despised what the English were doing in the matter of biblical criticism, and above all in philology. Yet now the acknowledged coryphaeus of them all, Harnack, not only admits the superiority of an old-time English book, but confesses that it is the best statement of the subject up to the present time, including his own. He constantly quotes from it, and it is evident that it has been the foundation of all of his arguments. It is not the first time that men have fetched from afar what they might have got just as well or better at home.
