John Chrysostom

What I have continually been saying, that we must frame our rebukes gently and gradually, this Paul doth here also; in that, being about to enter upon a subject full of many dangers and enough to tear up the Church from her foundations he uses very mild language. His word is that he "beseeches" them, and beseeches them "through Christ;" as though not even he were sufficient alone to make this supplication, and to prevail.

The emphatic force of the word "schism," I mean the name itself, was a sufficient accusation. For it was not that they had become many parts, each entire within itself, but rather the One Body which originally existed had perished. For had they been entire Churches, there might be many of them; but if they were divisions, in the next place, because he had sharply dealt with them by using the word "schism," he again softens and soothes them, saying, "That ye may be perfectly joined together in the same mind and in the same judgment." That is; since he had said, "That ye may all speak the same thing;" "do not suppose," he adds, "that I said concord should be only in words; I seek for that harmony which is of the mind." But since there is such a thing as agreement in words, and that hearty, not consenting, is no longer "perfected," nor fitted in to complete accordance. There is also such a thing as harmony of opinions, where there is not yet harmony of sentiment; for instance, when having the same faith we are not joined together in love: for thus, in opinions we are one, (for we think the same things,) but in sentiment not so. And such was the case at that time; this person choosing one leader, and that, another. For this reason he saith it is necessary to agree both in "mind" and in "judgment." For it was not from any difference in faith that the schisms arose, but from the division of their judgment through human contentiousness.
