John Chrysostom : "Alexander the coppersmith did me much evil; the Lord reward him according to his works." Here he again makes mention of his trial, not wishing merely to censure and accuse the man, but to prepare his disciple for the conflicts, that he might bear them firmly. Though they be mean and contemptible persons, and without honor, who cause these trials, they ought all, he says, to be borne with fortitude. For he who suffers wrong from any great personage, receives no little distinction from the superiority of him who does the wrong. But he who is injured by a vile and abject person, suffers the greater annoyance. "He did me much evil," he says, that is, he persecuted me in various ways. But these things will not go unpunished! For the Lord will reward him according to his works. As he said above: "What persecutions I endured, but out of them all the Lord delivered me." (2 Tim iii. 11.) So also here he consoles his disciples by a double consideration, that he himself had suffered wrong, and that the other would be rewarded for his evil deeds. Not that the Saints rejoice in the punishment of their persecutors, but that the cause of the Gospel required it, and the weaker would derive consolation from it. "Of whom be thou ware also; for he hath greatly withstood our words." That is, he is hostile to us, and opposes us. He has not said, Revenge, punish, expel him, although by the grace given him he might have so done, but he does no such thing; nor does he arm Timothy against him, but only commands him to avoid him, leaving vengeance to God, and for the consolation of the weaker he has said that He will reward him, which is a prophecy rather than an imprecation. — Homily on 2 Timothy 10 Oecumenius : Alexander the coppersmith did me much harm; the Lord will repay him according to his deeds. Beware of him yourself, for he strongly opposed our words. Paul also showed Timothy to endure bravely the troubles from common people. For it is painful to be wronged, especially by common people. the Lord will repay him. Not because Paul was pleased with the punishment, but because for the sake of the weaker among the believers, those who were excessively opposing had to suffer badly, so that they would not despise the weakness of the preaching. according to his deeds. Or that it is a prophecy of things to come, not a curse. Beware of him yourself. Paul did not say, Punish, punish (for it was also permitted for Timothy to do this through the spirit), but, Beware. Do you see that he does not allow punishment? But the "Beware" is like a warning. opposed our words. That is, to those of the preaching. — COMMENTARY ON 2 TIMOTHY Tertullian : The famous Alexander, too, instigated by his love of disputation in the true fashion of heretical temper, has made himself conspicuous against us; he will have us say that Christ put on flesh of an earthly origin, in order that He might in His own person abolish sinful flesh. — On the Flesh of Christ
