1 Corinthians 5:2

And "tell me not," saith he, "that the fornicator is but one: the charge hath become common to all." Wherefore at once he added, "and ye are puffed up:" he said not, "with the sin;" for this would imply want of all reason: but with the doctrine you have heard from that person. This however he set not down himself, but left it undetermined, that he might inflict a heavier blow. And mark the good sense of Paul. Having first overthrown the wisdom from without, and signified that it is nothing by itself although no sin were associated with it; then and not till then he discourses about the sin also. For if by way of comparison with the fornicator who perhaps was some wise one, he had maintained the greatness of his own spiritual gift; he had done no great thing: but even when unattended with sin to take down the heathen wisdom and demonstrate it to be nothing, this was indicating its extreme worthlessness indeed. Wherefore first, as I said, having made the comparison, he afterwards mentions the man's sin also. And with him indeed he condescends not to debate, and thereby signifies the exceeding greatness of his dishonor. But to the others he saith, "You ought to weep and wail, and cover your faces, but now ye do the contrary." And this is the force of the next clause, "And ye are puffed up, and did not rather mourn." "And why are we to weep?" some might say. Because the reproach hath made its way even unto the whole body of your Church. "And what good are we to get by our weeping?" "That such an one should be taken away from you." Not even here doth he mention his name; rather, I should say, not any where; which in all monstrous things is our usual way. And he said not, "Ye have not rather cast him out," but, as in the case of any disease or pestilence, "there is need of mourning," saith he, "and of intense supplication, 'that he may be taken away.' And you should have used prayer for this, and left nothing undone that he should be cut off." Nor yet doth he accuse them for not having given him information, but for not having mourned so that the man should be taken away; implying that even without their Teacher this ought to have been done, because of the notoriety of the offence.
