As we think about food, here's a good few paragraphs from Doug Wilson:
"if you are a fastidious eater, and cannot be troubled to be a charitable guest at the table of another, then you are an enemy of love.
"In the meantime, every Christian who understands the gospel must fight — as part of our sanctification — the impulse to despise the food that God has given to somebody else. This applies even if the apple was not locally grown, if the coffee was not certified fair trade, if the bread came from a monoculture crop, if the asparagus was modified to taste horrible to asparagus predators, or if the food in question has “chemicals” in it.
"We live in a sinful and fallen world, so food must indeed be sanctified. But the only thing that sanctifies it is the gravy of grace and gratitude (1 Tim. 4:4-5)."
