Irenaeus : That he was not merely a follower, but also a fellow-labourer of the apostles, but especially of Paul, Paul has himself declared also in the Epistles, saying: "Demas hath forsaken me, ... and is departed unto Thessalonica; Crescens to Galatia, Titus to Dalmatia. Only Luke is with me." From this he shows that he was always attached to and inseparable from him. And again he says, in the Epistle to the Colossians: "Luke, the beloved physician, greets you." But surely if Luke, who always preached in company with Paul, and is called by him "the beloved," and with him performed the work of an evangelist, and was entrusted to hand down to us a Gospel, learned nothing different from him (Paul), as has been pointed out from his words, how can these men, who were never attached to Paul, boast that they have learned hidden and unspeakable mysteries? — Against Heresies Book III John Chrysostom : "Luke, the beloved physician, saluteth you." This is the Evangelist. It is not to lower this man that he placeth him after, but to raise the other, viz. Epaphroditus. It is probable that there were others called by this name. "And Demas," he says. After saying, "Luke, the physician, saluteth you," he added, "the beloved." And no small praise is this, but be beloved of Paul even great exceedingly. — Homily on Colossians 12
