What does 1 Corinthians 8:1 mean?

John Gill's Exposition of the Bible
1 Corinthians 8:1

Now as touching things offered unto idols
This was another of the things the Corinthians wrote to the apostle about, desiring to have his judgment in; it was a controversy that had been before moved, whether it was lawful to eat things that had been sacrificed to idols. This was considered in the council at Jerusalem, ( Acts 15:28 Acts 15:29 ) and it was agreed to, for the peace of the churches, that the Gentiles, among other things, be advised to abstain from them; which, it seems, the church at Corinth knew nothing of, for the controversy was now moved among them: some that were weak in the faith, and had not, at least, clear notions of Gospel liberty, thought it very criminal and sinful to eat them; others that had, or boasted they had, more knowledge, would not only eat them privately at home, having bought them of the Heathen priests, or in the common meat markets, where they were exposed to sale, and at public feasts, to which they were invited by their friends; but would even go into an idol's temple, and sit and eat them there, to the great grief and prejudice of weak Christians; and what they had to plead in their own defence was their knowledge, to which the apostle here replies:

we know that we all have knowledge;
said either affirmatively and seriously; and the meaning is, that the apostles and other Christians knew, and were conscious to themselves of their light and knowledge, and were assured, and might affirm with confidence, that they all, or the most part, only some few excepted, see ( 1 Corinthians 8:7 ) had the same knowledge of Christian liberty as they had; knew that an idol was nothing, and that eating meats offered to them could not defile, or do them any hurt; for they were very sensible there was nothing common or unclean of itself, and yet did not think fit to make use of their knowledge to the grieving and wounding of their fellow Christians: or else this is said ironically, we are wise folks; you particularly are men of knowledge, and wisdom will die with you; you know that you know; you are very knowing in your own conceits, and very positive as to your knowledge. It was the saying of Socrates, that that this one thing he knew, that he knew nothing; but men wise in their own opinions know everything:

knowledge puffeth up;
not true knowledge; not that which comes from above, which is gentle and easy to be entreated; not sanctified knowledge, or that which has the grace of God going along with it; that makes men humble, and will not suffer them to be puffed up one against another; but a mere show of knowledge, knowledge in conceit, mere notional and speculative knowledge, that which is destitute of charity or love:

but charity edifieth;
that is, a man that has knowledge, joined with love to God, and his fellow Christians, will seek for that which makes for the edification of others; and without this all his knowledge will be of no avail, and he himself be nothing.
