2 Timothy 4:11

1. But that this Luke was inseparable from Paul, and his fellow-labourer in the Gospel, he himself clearly evinces, not as a matter of boasting, but as bound to do so by the truth itself. For he says that when Barnabas, and John who was called Mark, had parted company from Paul, and sailed to Cyprus, “we came to Troas;” and when Paul had beheld in a dream a man of Macedonia, saying, “Come into Macedonia, Paul, and help us,” “immediately,” he says, “we endeavoured to go into Macedonia, understanding that the Lord had called us to preach the Gospel unto them. Therefore, sailing from Troas, we directed our ship’s course towards Samothracia.” And then he carefully indicates all the rest of their journey as far as Philippi, and how they delivered their first address: “for, sitting down,” he says, “we spake unto the women who had assembled;” and certain believed, even a great many. …

2. If it should be asked why he addresses Epistles to Titus and Timothy alone, though Silas was approved, as also was Luke, for he writes, “Only Luke is with me” ( 2 Tim. iv. 11 .), and Clement was one of his associates, of whom he says, “with Clement and other my fellow-laborers” ( Philip. iv. 3 .), for what reason then does he write only to Titus and Timothy? It is because he had already committed the care of churches to these, and certain marked places had been assigned to them, but the others were in attendance upon him. For so preëminent in virtue was Timothy, that his youth was no impediment to his promotion; therefore he writes, “Let no man despise thy youth” ( 1 Tim. iv. 12, and v. 2 .); and again, “The younger women as sisters.” For where there is virtue, all other things are superfluous, and there can be no impediment. …

2 Timothy iv. 9-13 “Do thy diligence to come shortly unto me: For Demas hath forsaken me, having loved this present world, and is departed unto Thessalonica; Crescens to Galatia, Titus unto Dalmatia. Only Luke is with me. Take Mark, and bring him with thee: for he is profitable to me for the ministry. And Tychicus have I sent to Ephesus. The cloak that I left at Troas with Carpus, when thou comest, bring with thee, and the books, but especially the parchments.”

Why then does he put Luke last? And yet he elsewhere says, “Only Luke is with me” ( 2 Tim. iv. 11 .), and “Demas,” he says, was one of those who “forsook him, having loved the present world.” ( 2 Tim. iv. 10 .) All these things, although they are mentioned elsewhere, yet nevertheless ought not to be passed over here without enquiry, nor ought we merely to hear them as things of course. But how comes he to say that he who forsook him salutes them? For “Erastus,” he says, “abode at Corinth.” ( 2 Tim. iv. 20 .) He adds Epaphras, both as known to them, and being of their country. And Mark, as being himself also an admirable man. Why then does he number Demas with these? Perhaps it was after this that he became more remiss, when he saw the dangers multiplied. But Luke being last became first. …

6. In his second epistle to Timothy, moreover, he indicates that Luke was with him when he wrote, but at his first defense not even he. Whence it is probable that Luke wrote the Acts of the Apostles at that time, continuing his history down to the period when he was with Paul.
