8:1 Now concerning food offered to idols. The Corinthians had raised the issue of idolatry dealt with in chs. 8–10, but the precise nature of their question is difficult to determine. According to some interpreters, the issues discussed in ch. 8 and in 10:25–30 are one and the same. Others, on the basis of 8:10, argue that ch. 8 deals with the serious problem that some Christians were attending pagan feasts and eating the food served there, while 10:25–30 concerns the lesser problem of meat purchased in the market.
all of us possess knowledge. Paul addresses the sin of arrogance as an introduction to the subject of idolatry (vv. 1–3). These comments reveal that behind the behavior of the Corinthians (or at least an important group among them) lay a serious problem of attitude. Their conduct was not guided by love (cf. ch. 13) but by pride.
