For if he that cometh
Meaning either some particular man, the apostle might have had some information of, who came from Judea to Corinth, under the character of a true apostle; or anyone of the false apostles whatever, who came of their own accord, and was never sent by Christ, or by any of his churches:
preacheth another Jesus whom we have not preached;
that is, if he proposes and recommends in his ministry, a better Saviour and Redeemer than had been preached by the apostles; one that was better qualified, and more fit for the purposes of salvation; one that they could more safely venture their souls upon, and believe in, as the alone able and all sufficient Saviour, a thing impossible to be: or the sense is, if this other apostle taught the doctrine of salvation by Christ, in another and better method and in a clearer manner, more to the honour of the Redeemer, the glory of God, and the good of their souls, they would have some reason then to pay a greater regard to him:
or if ye receive another spirit which ye have not received;
a better spirit than the Spirit of God, which the had received through the preaching of the Gospel by the apostles; either for graces, for they had received him as a spirit of regeneration and conversion, of sanctification and faith, of adoption and liberty, of peace and joy, and comfort; or for gifts, both ordinary and extraordinary, which could not possibly be; the spirit which the contrary ministers brought with it, and tended to not generate in them, must be the reverse of this, even a spirit of bondage again to fear:
or another Gospel which ye have not accepted,
or "embraced"; a better Gospel than had been preached by the apostles, and received by them; which contained more wholesome doctrines, more comfortable truths, more excellent promises, better tidings of good things, than those of peace, pardon, righteousness, life, and salvation, by a crucified Jesus; proposed a better scheme of things, more for the honour of the divine perfections, and for the comfort and safety of believers; and which laid a better foundation for faith and hope, and tended more to encourage true religion and powerful godliness:
ye might well bear with him;
receive his doctrine, submit to his authority, and prefer him to the apostles: but since another and a better Saviour than Jesus of Nazareth could not be proposed, or the doctrine of salvation by him be preached in another and better manner than it was; nor had they received, nor could they receive, another and a better spirit, than the spirit of grace and truth, which was communicated to them, through the apostle's ministry; nor was a better and a more excellent Gospel preached to them, than what they had heard; therefore they ought not to connive at, indulge and tolerate, such a false apostle among them, which it seems they did; and was the reason of the apostle's fears and jealousies, before expressed: and besides, supposing that this man that was among them, and caressed by many of them, did preach the same Jesus, and the same doctrine of salvation by him, and the same Spirit and power went along with his ministry, it being the same Gospel that was preached by Paul and others, there was no reason why he should be set up above them, who had been the instruments of conveying the Gospel, and the Spirit of it, to them, long before he was known by them.
