Demas forsook me, having loved this present world, and departed into Thessalouica, Crescens to Galatia, Titus unto Dalmatia: 11. Only Luke is with me."
He is not mentioned elsewhere in the New Testament;(1) and his name is not again met with till Irenæus ascribes to him the authorship of the Gospel and Acts. There is nothing in these Pauline Epistles confirming the statement of the Fathers, but it is highly probable that these references to him largely contributed to suggest his name as the author of the Acts, the very omission of his name from the work itself protecting him from objections connected with the passages in the first person to which other followers of Paul were exposed, upon the traditional view of the composition. Irenæus evidently knew nothing about him, except what he learnt from these Epistles, and derives from his theory that Luke wrote the Acts, and speaks as an eye-witness in the passages where the first person is used. From these he argues that Luke was inseparable from Paul, and was his fellow-worker in the Gospel, and he refers, in proof of this, to Acts xvi. 8 ff.,(2) 13 ff., xx. 5 ff., and the later chapters, all the details of which he supposes Luke to have carefully written down. He then continues: "But that he was not only a follower, but likewise a fellow-worker of the Apostles, but particularly of Paul, Paul himself has also clearly shown in the Epistles, saying:..." and he quotes 2 Tim. iv. 10, 11, ending: "Only Luke is with me," and then adds, "whence he shows that he was
always with him and inseparable from him, &c, Ac."(1) The reasoning of the zealous Father deduces a great deal from very little, it will be observed, and in this elastic way tradition "enlarged its borders" and assumed unsubstantial dimensions. Later writers have no more intimate knowledge of Luke, although Eusebius states that he was born at Antioch,(2) a tradition likewise reproduced by Jerome.(3) Jerome further identifies Luke with "the brother, whose praise in the Gospel is throughout all the churches" mentioned in 2 Cor. viii. 18, as accompanying Titus to Corinth.(4) At a later period, when the Church required an early artist for its service, Luke the physician was honoured with the additional title of painter.(5) Epiphanius,(6) followed later by some other
writers, represented him to have been one of the seventy-two disciples, whose mission he alone of all New Testament writers mentions. The view of the Fathers, arising out of the application of their tradition to the features presented by the Gospel and Acts, was that Luke composed his Gospel, of the events of which he was not an eye-witness, from information derived from others, and his Acts of the Apostles from what he himself, at least in the parts in which the first person is employed, had witnessed.1 It is generally supposed that Luke was not born a Jew, but was a Gentile Christian.
Some writers endeavour to find a confirmation of the tradition, that the Gospel and Acts were written by Luke "the beloved physician," by the supposed use of peculiarly technical medical terms,(2) but very little weight is attached by any one to this feeble evidence which is repudiated by most serious critics, and it need not detain us.
As there is no indication, either in the Gospel or the Acts, of the author's identity proceeding from himself, and tradition does not offer any alternative security, what testimony can be produced in support of the ascription of
these writings to "Luke"? To this question Ewald shall reply: "In fact," he says, "we possess only one ground for it, but this is fully sufficient. It lies in the designation of the third Gospel as that 'according to Luke' which is found in all MSS. of the four Gospels. For the quotations of this particular Gospel under the distinct name of Luke, in the extant writings of the Fathers, begin so late that they cannot be compared in antiquity with that superscription; and those known to us may probably themselves only go back to this superscription. We thus depend almost alone on this superscription."(1) Ewald generally does consider his own arbitrary conjectures "fully sufficient," but it is doubtful, whether in this case, any one who examines this evidence will agree with him. He himself goes on to admit, with all other critics, that the superscriptions to our Gospels do not proceed from the authors themselves, but were added by those who collected them, or by later readers to distinguish them.(2) There was no author's name attached to Marcion's Gospel, as we learn from Tertullian.(3) Chrysostom
