even as the testimony concerning Christ was confirmed in you,

Now concerning things sacrificed to idols, we know that we all have knowledge. Knowledge makes arrogant, but love edifies.

Therefore concerning the eating of things sacrificed to idols, we know that there is no such thing as an idol in the world, and that there is no God but one.

If I partake with thankfulness, why am I slandered concerning that for which I give thanks?

Now concerning spiritual gifts, brethren, I do not want you to be unaware.

Now concerning the collection for the saints, as I directed the churches of Galatia, so do you also.

But concerning Apollos our brother, I encouraged him greatly to come to you with the brethren; and it was not at all his desire to come now, but he will come when he has opportunity.
