This argument about the "we sections" can be completely overthrown by a consideration of the _linguistic evidence_ of Acts. If language implies anything, the peculiarities of Acts imply that the author of the "we sections," who was a companion of St. Paul, was the author of the whole book. And they also show that the author of the whole book was the person who wrote the third Gospel. There are many words and phrases found only in the "we sections" and in the rest of Acts. There is, too, a large number of words and phrases in the "we sections" which are rarely used in those books of the New Testament which are _not_ attributed to St. Luke, and occur frequently in the rest of Acts and in St. Luke's Gospel. If {104} we compare Acts with St. Luke's Gospel, we find that Acts contains 108 out of 140 which are characteristic of this Gospel, whereas it contains only about a half of those which are characteristic of Matt. and Mark. There are 58 Greek words which are found in both Acts and Luke and nowhere else in the New Testament.[2] Among the terms which serve as connecting links between St. Luke's Gospel and Acts, including the "we sections," occur various medical phrases. It is becoming more and more widely recognized that these phrases imply that the writer was a physician, such as we know St. Luke to have been (Col. iv. 14). It is all the more remarkable that many of the words peculiar to Acts are found in St. Luke's contemporary, the physician Dioscorides. It is true that the sections taken from Mark show numerous "Lucan" characteristics as they appear in our third Gospel, but these characteristics are due to the third evangelist, and not to St. Mark. So, it can be urged, the "Lucan" characteristics in the "we sections" are due not to the author, but to an expert editor of a later time. In reply, we can answer that the cases are not strictly parallel. For if the "we sections" are not by the writer of Acts, he must have almost entirely rewritten them, and, at the same time, have been guilty of a gross fraud, which he stupidly dropped in passages where it could have been effectively used.
