Summary: Paul takes the Corinthians' own words and clarifies them. With regard to the cleanliness of food, he'd much rather not eat and not cause someone to stumble than persuade someone, even passively, to sin.
Response: Apparently this doublespeak has been happening for a while now and I'm just now noticing. Of course, it's not just about food; it's different for each person. I pray God shows me how I might choose more carefully what I do, buy, and say that He can do better work through me.
