John Calvin Commentary 2 Corinthians 7:2

"Open your hearts to us: we wronged no man, we corrupted no man, we took advantage of no man." — 2 Corinthians 7:2 (ASV)

Make room for us. Again he returns from a statement of doctrine to address what more specifically concerns himself, but simply with this intention—that his efforts in admonishing the Corinthians may not be in vain. Furthermore, he closes the preceding admonition with the same statement he had used as a preface. For what is meant by the expressions Receive us, or Make room for us? It is equivalent to, Be you enlarged (2 Corinthians 6:13); that is, “Do not allow corrupt affections or unfavorable perceptions to prevent this doctrine from entering your minds and finding a place within you. For as I devote myself to your salvation with a fatherly zeal, it would be unfitting for you to turn a deaf ear to me.”

We have done injury to no man. He declares that there is no reason why they should have their minds alienated from him, since he had not given them cause for offense in anything. Now he mentions three kinds of offenses, regarding which he declares himself to be guiltless:

1. The first is, manifest hurt or injury.
2. The second is, the corruption that springs from false doctrine.
3. The third is, defrauding or cheating in worldly goods.

These are three things by which, for the most part, pastors tend to alienate the minds of the people from them: when they conduct themselves in an overbearing manner and, using their authority as a pretext, erupt into tyrannical cruelty or unreasonableness; or when they lead astray from the right path those for whom they should have been guides, and infect them with the corruption of false doctrine; or when they show an insatiable covetousness by eagerly desiring what belongs to another.

If anyone wishes for a more concise summary:

1. The first is, fierceness and an abuse of power by excessive insolence.
2. The second, unfaithfulness in teaching.
3. The third, avarice.
