1 Corinthians 8:4-6
4-6Some people say, quite rightly, that idols have no actual existence, that there's nothing to them, that there is no God other than our one God, that no matter how many of these so-called gods are named and worshiped they still don't add up to anything but a tall story. They say—again, quite rightly—that there is only one God the Father, that everything comes from him, and that he wants us to live for him. Also, they say that there is only one Master—Jesus the Messiah—and that everything is for his sake, including us. Yes. It's true.
7In strict logic, then, nothing happened to the meat when it was offered up to an idol. It's just like any other meat. I know that, and you know that. But knowing isn't everything. If it becomes everything, some people end up as know-it-alls who treat others as know-nothings. Real knowledge isn't that insensitive.
We need to be sensitive to the fact that we're not all at the same level of understanding in this. Some of you have spent your entire lives eating "idol meat," and are sure that there's something bad in the meat that then becomes something bad inside of you. An imagination and conscience shaped under those conditions isn't going to change overnight.
