1 Corinthians 8:2

2 Those who think they know something really don't know as they ought to know.

1 Corinthians 8:2 Meaning and Commentary

1 Corinthians 8:2

And if any man think that he knows anything
Whoever has an opinion of himself, or is conceited with his own knowledge, and fancies that he knows more than he does; which is always the case of those that are elated with their knowledge, and treat others with contempt, and have no regard to their peace and edification:

he knoweth nothing yet as he ought to know;
if he did, he would know this, that he ought to consult the peace, comfort, and edification of his brother; and therefore whatever knowledge he may fancy he has attained to, or whatever he may be capable of, and hereafter obtain, for the present he must be put down for a man that knows nothing as he should do; for he knows neither his duty to God nor man; if he knew the former, he would know the latter.

1 Corinthians 8:2 In-Context

1 Now, concerning what you wrote about food offered to idols. It is true, of course, that "all of us have knowledge," as they say. Such knowledge, however, puffs a person up with pride; but love builds up.
2 Those who think they know something really don't know as they ought to know.
3 But the person who loves God is known by him.
4 So then, about eating the food offered to idols: we know that an idol stands for something that does not really exist; we know that there is only the one God.
5 Even if there are so-called "gods," whether in heaven or on earth, and even though there are many of these "gods" and "lords,"
