It is obvious that since nothing like this was done by any of Paul's colleagues, the unanimous verdict on him was that he was of good character, with no trace of avarice in him.
Wherefore also he proceeds by question, saying, "I exhorted Titus, and with him I sent the brother. Did Titus make a gain of you?" 'walked he not just as I walked.' That is to say, neither did he receive. Seest thou how intense a strictness [is here], in that he not only keeps himself clear of that receiving, but so modulates those also who are sent by him that he may not give so much as a slight pretence to those who were desirous of attacking him. For this is far greater than that which the Patriarch did. For he indeed, when he had returned from his victory, and the king would have given him the spoil, refused to accept aught save what the men had eaten; but this man neither himself enjoyed [from them] his necessary food, nor allowed his partners to partake of such: thus abundantly stopping the mouths of the shameless. Wherefore he makes no assertion, nor does he say that they did not receive either; but what was far more than this, he cites the Corinthians themselves as witnesses that they had received nothing, that he may not seem to be witnessing in his own person, but by their verdict; which course we are accustomed to take in matters fully admitted and about which we are confident. 'For tell me,' he says, 'Did any one of those who were sent by us make unfair gain of you?' He did not say, 'Did any one receive aught from you?' but he calls the things 'unfair gain;' attacking them and shaming them exceedingly, and showing that to receive of an unwilling [giver] is 'unfair gain.' And he said not 'did Titus?' but, "did any?" 'For ye cannot say this either,' he says, 'that such an one certainly did not receive, but another did. No single one of those who came did so.' "I exhorted Titus." This too is severely said. For he did not say, 'I sent Titus,' but, 'I exhorted' him; showing that if he had received even, he would have done so justly; but, nevertheless, even so he remained pure. Wherefore he asks them again, saying, "Did Titus take any advantage of you? Walked we not by the same spirit?" What means, "by the same spirit?" He ascribes the whole to grace and shows that the whole of this praise is the good result not of our labors, but of the gift of the Spirit and of Grace. For it was a very great instance of grace that although both in want and hunger they would receive nothing for the edification of the disciples. "Walked we not in the same steps?" That is to say, they did not depart the least from this strictness, but preserved the same rule entire.
A rebuke is contained in these words as well. He does not say: I sent, but: I urged, showing that even if Titus took anything, he took it by right, because he came at the request; but he nevertheless remained blameless. Together with him he also sent a certain other brother.
That is, was it not by the same spiritual gift? He calls the disinterestedness amid straitened circumstances a gift, and though it was his own doing, he ascribes it to God.
And they (those sent by me) did not deviate from my path in anything, but showed the same strictness toward themselves. Notice how Paul not only established himself in this strictness, but also his co-workers, having taught them not to stain themselves even with rightful collection.
He excludes their suspicion in particular when he says: I urged Titus to go, and sent the brother with him. As if to say: none of those whom I sent to you overreached you. For I sent Titus to you with entreaties. And this is what he says: I urged Titus to go, and sent the brother with him, namely, Barnabas or Luke: "With him," namely Titus, "we are sending the brother," namely one of those mentioned, "who is famous among all the churches for his preaching of the gospel" (2 Cor. 8:18). But did Titus take advantage of you? As if to say: No: "But thanks be to God who puts the same earnest care for you into the heart of Titus" (2 Cor. 8:16). That Titus did not overreach them he proves by showing that Titus was of the same mind as the Apostle, and he mentions two points of similarity: first, in the heart; hence he says: Did we not act in the same spirit?, i.e., have the same will; or we were inspired by the same spirit to act well and correctly: "Since we have the same spirit of faith as he had who wrote, 'I believed, and so I spoke,' we too believe, and so we speak" (2 Cor. 4:13). Secondly, in work; hence he says: Did we not take the same steps, i.e., intent on the same works? That is to say, in the steps of Christ, for I walk in the steps of Christ: "I have kept his way," namely, Christ's, "and have not turned aside" (Job 23:11); "Christ also suffered for you, leaving you an example, that you should follow in his steps" (1 Pet. 2:21). And Titus follows my steps: "Be imitators of me, as I am of Christ" (1 Cor. 11:1). Therefore, if he agrees with me in will and in work, and I have not overreached you and do not intend to overreach you, the conclusion is evident. That he did not overreach them is clear from Matt. (7:16): "By their fruits you shall know them."
