1 Corinthians 8:1

"Now concerning things sacrificed to idols, we know that we all have knowledge." Leaving alone the weak, which he always doth, he discourses with the strong first. And this is what he did also in the Epistle to the Romans, saying, "But thou, why dost thou judge thy brother?" for this is the sort of person that is able to receive rebuke also with readiness. Exactly the same then he doth here also. And first he makes void their conceit by declaring that this very thing which they considered as peculiar to themselves, the having perfect knowledge, was common to all. Thus, "we know," saith he, "that we all have knowledge." For if allowing them to have high thoughts, he had first pointed out how hurtful the thing was to others, he would not have done them so much good as harm. For the ambitious soul when it plumes itself upon any thing, even though the same do harm to others, yet strongly adheres to it because of the tyranny of vain-glory. Wherefore Paul first examines the matter itself by itself: just as he had done before in the case of the wisdom from without, demolishing it with a high hand. But in that case he did it as we might have expected: for the whole thing was altogether blameworthy and his task was very easy. Wherefore he signifies it to be not only useless, but even contrary to the Gospel. But in the present case it was not possible to do this. For what was done was of knowledge, and perfect knowledge. Nor was it safe to overthrow it, and yet in no other way was it possible to cast out the conceit which had resulted from it. What then doeth he? First, by signifying that it was common, he curbs that swelling pride of theirs. For they who possess something great and excellent are more elated, when they alone have it; but if it be made out that they possess it in common with others, they no longer have so much of this feeling. First then he makes it common property, because they considered it to belong to themselves alone. Next, having made it common, he does not make himself singly a sharer in it with them; for in this way too he would have rather set them up; for as to be the only possessor elates, so to have one partner or two perhaps among leading persons has this effect just as much. For this reason he does not mention himself but all: he said not, "I too have knowledge," but, "we know that we all have knowledge." This then is one way, and the first, by which he cast down their pride; the next hath greater force. What then is this? In that he shews that not even this thing itself was in all points complete, but imperfect, and extremely so. And not only imperfect, but also injurious, unless there were another thing joined together with it. For having said that "we have knowledge," he added, "Knowledge puffeth up, but love edifieth:" so that when it is without love, it lifts men up to absolute arrogance. "And yet not even love," you will say, "without knowledge hath any advantage." Well: this he did not say; but omitting it as a thing allowed by all, he signifies that knowledge stands in extreme need of love. For he who loves, inasmuch as he fulfils the commandment which is most absolute of all, even though he have some defects, will quickly be blest with knowledge because of his love; as Cornelius and many others. But he that hath knowledge but hath not love, not only shall gain nothing more, but shall also be cast out of that which he hath, in many cases falling into arrogance. It seems then that knowledge is not productive of love, but on the contrary debars from it him that is not on his guard, puffing him up and elating him. For arrogance is wont to cause divisions: but love both draws together and leads to knowledge. And to make this plain he saith, "But if any man loveth God, the same is known of Him." So that "I forbid not this," saith he, "namely, your having perfect knowledge; but your having it with love, that I enjoin; else is it no gain, but rather loss." Do you see how he already sounds the first note of

Paul means that knowledge only does good in company with love. Otherwise it merely puffs a man into pride.
