1Cor.10.28

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:

1Cor.10.28

On the other hand, if he goes out of his way to tell you that this or that was sacrificed to god or goddess so-and-so, you should pass. Even though you may be indifferent as to where it came from, he isn't, and you don't want to send mixed messages to him about who you are worshiping.

1Cor.10.28

But if anyone says to you, "This has been offered in sacrifice," then do not eat it, both for the sake of the man who told you and for conscience' sake--

1Cor.10.28

But if anyone says to you, "This was offered to idols," do not eat it for the sake of the one who told you, and for conscience' sake; for "the earth is the LORD's, and all its fullness."
