He receives here a remarkable and honourable title, "my fellow-prisoner." I suppose that it is to be taken literally, and that Aristarchus was, in some way, at the moment of writing, sharing Paul's imprisonment. Now it has been often noticed that, in the Epistle to Philemon, where almost all these names re-appear, it is not Aristarchus, but Epaphras, who is honoured with this epithet; and that interchange has been explained by an ingenious supposition that Paul's friends took it in turn to keep him company, and were allowed to live with him, on condition of submitting to the same restrictions, military guardianship, and so on. There is no positive evidence in favour of this, but it is not improbable, and, if accepted, helps to give an interesting glimpse of Paul's prison life, and of the loyal devotion which surrounded him. Mark comes next. His story is well known--how twelve years before, he had joined the first missionary band from Antioch, of which his cousin Barnabas was the leader, and had done well enough as long as they were on known ground, in Barnabas' (and perhaps his own) native island of Cyprus, but had lost heart and run home to his mother as soon as they crossed into Asia Minor. He had long ago effaced the distrust of him which Paul naturally conceived on account of this collapse. How he came to be with Paul at Rome is unknown. It has been conjectured that Barnabas was dead, and that so, Mark was free to join the Apostle; but that is unsupported supposition. Apparently he is now purposing a journey to Asia Minor, in the course of which, if he should come to Colossæ (which was doubtful, perhaps on account of its insignificance), Paul repeats his previous injunction, that the church should give him a cordial welcome. Probably this commendation was given because the evil odour of his old fault might still hang about his name. The calculated emphasis of the exhortation, "receive him," seems to show that there was some reluctance to give him a hearty reception and take him to their hearts. So we have an "undesigned coincidence." The tone of the injunction here is naturally explained by the story in the Acts. So faithful a friend did he prove, that the lonely old man, fronting death, longed to have his affectionate tending once more; and his last word about him, "Take Mark, and bring him with thee, for he is profitable to me for _the ministry_," condones the early fault, and restores him to the office which, in a moment of selfish weakness, he had abandoned. So it is possible to efface a faultful past, and to acquire strength and fitness for work, to which we are by nature most inapt and indisposed. Mark is an instance of early faults nobly atoned for, and a witness of the power of repentance and faith to overcome natural weakness. Many a ragged colt makes a noble horse.
