1 Corinthians, chapter 10
"27": If any of them that believe not bid you to a feast, and ye be disposed to go; whatsoever is set before you, eat, asking no question for conscience sake.
"28": But if any man say unto you, This is offered in sacrifice unto idols, eat not for his sake that shewed it, and for conscience sake: for the earth is the Lord's, and the fulness thereof:
"29": Conscience, I say, not thine own, but of the other: for why is my liberty judged of another man's conscience?
"30": For if I by grace be a partaker, why am I evil spoken of for that for which I give thanks?
"31": Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God.
