1 Corinthians 8:8

But food will not commend us to God: neither if we eat not, are we the worse; nor, if we eat, are we the better.

In a sense, it was absolutely immaterial where the meat came from, whether sacrificed to idols or not; because salvation is simply not a matter of diet at all. Christ took away all prohibitions, "making all meats clean" (Mark 7:19); and Paul himself wrote that "every creature of God is good, and nothing is to be rejected, etc." (1 Timothy 4:4); but for a Christian who had not learned such vital truth, and who considered it sinful to eat certain things, it was definitely a sin for him to do so. In the situation at Corinth, therefore, it was not a question of determining what was right or wrong, merely in the abstract sense.
