The question that rises to the Apostle's lips as he confronts the solemn situation created by the Gospel is not directly answered. "Who is sufficient for these things? Who? I say. For we are not as the many,[22] who corrupt the Word of God: but as of sincerity, but as of God, in the sight of God, we speak in Christ." Paul is conscious as he writes that his awful sense of responsibility as a preacher of the Gospel is not shared by all who exercise the same vocation. To be the bearer and the representative of a power with issues so tremendous ought surely to annihilate every thought of self; to let personal interest intrude is to declare oneself faithless and unworthy. We are startled to hear from Paul's lips what at first sight seems to be a charge of just such base self-seeking laid against the majority of preachers. "We are not as the many, corrupting the Word of God." The expressive word rendered here "corrupting" has the idea of self-interest, and especially of petty gain, at its basis. It means literally to sell in small quantities, to retail for profit. But it was specially applied to tavern-keeping, and extended to cover all the devices by which the wine-sellers in ancient times deceived their customers. Then it was used figuratively, as here; and Lucian, _e.g._, speaks of philosophers as selling the sciences, and in most cases (ὁι πολλοί: a curious parallel to St. Paul), like tavern keepers, "blending, adulterating, and giving bad measure." It is plain that there are two separable ideas here. One is that of men qualifying the Gospel, infiltrating their own ideas into the Word of God, tempering its severity, or perhaps its goodness, veiling its inexorableness, dealing in compromise. The other is that all such proceedings are faithless and dishonest, because some private interest underlies them. It need not be avarice, though it is as likely to be this as anything else. A man corrupts the Word of God, makes it the stock-in-trade of a paltry business of his own, in many other ways than by subordinating it to the need of a livelihood. When he exercises his calling as a minister for the gratification of his vanity, he does so. When he preaches not that awful message in which life and death are bound up, but himself, his cleverness, his learning, his humour, his fine voice even or fine gestures, he does so. He makes the Word minister to him, instead of being a minister of the Word; and that is the essence of the sin. It is the same if ambition be his motive, if he preaches to win disciples to himself, to gain an ascendency over souls, to become the head of a party which will bear the impress of his mind. There was something of this at Corinth; and not only there, but wherever it is found, such a spirit and such interests will change the character of the Gospel. It will not be preserved in that integrity, in that simple, uncompromising, absolute character which it has as revealed in Christ. Have another interest in it than that of God, and that interest will inevitably colour it. You will make it what it was not, and the virtue will depart from it.
In contrast with all such dishonest ministers, the Apostle represents himself and his friends speaking "as of sincerity." They have no mixture of motives in their work as evangelists; they have indeed no independent motives at all: God is leading them in triumph, and proclaiming His grace through them. It is He who prompts every word (ὡς ἐκ Θεοῦ). Yet their responsibility and their freedom are intact. They feel themselves in His presence as they speak, and in that presence they speak "in Christ." "In Christ" is the Apostle's mark. Not in himself apart from Christ, where any mixture of motives, any process of adulteration, would have been possible, but only in that union with Christ which was the very life of his life, did he carry on his evangelistic work. This was his final security, and it is still the only security, that the Gospel can have fair play in the world.
