John Calvin Commentary 2 Corinthians 11:4

"For if he that cometh preacheth another Jesus, whom we did not preach, or [if] ye receive a different spirit, which ye did not receive, or a different gospel, which ye did not accept, ye do well to bear with [him]." — 2 Corinthians 11:4 (ASV)

For if he that cometh. He now reproves the Corinthians for the excessive readiness they showed to receive the false apostles. For while they were excessively morose and irritable towards Paul himself, so that on any, even the least occasion, they were offended if he gave them even the slightest reproof, on the other hand, there was nothing they did not tolerate from the false apostles.

They willingly endured their pride, haughtiness, and unreasonableness. He condemns such absurd reverence because, meanwhile, they showed no discrimination or judgment.

“How is it that they take so much liberty with you, and you submit patiently to their control? If they had brought you another Christ, or another gospel, or another Spirit, different from what you received through my hands, I would certainly approve of your regard for them, for they would deserve such honor. But since they have conferred nothing on you that I had not given you previously, what sort of gratitude do you show in almost adoring those to whom you are indebted for nothing, while you despise me, through whom God has bestowed so many distinguished benefits on you?”

Such is the reverence that is shown even today by Papists towards their pretended Bishops. For while they are oppressed by their excessively harsh tyranny, they submit to it without difficulty; but, at the same time, they do not hesitate to treat Christ himself with contempt.

The expressions — another Christ, and another gospel, are used here in a different sense from the sense they have in Galatians 1:8. For another is used there in opposition to what is true and genuine, and therefore it means false and counterfeit. Here, on the other hand, he means to say — “If the gospel had come to you through their ministry, and not through mine.”
