1 Corinthians 8:6-7

yet for us there is only one God—the Father. Out of him is all things, and our lives are lived for him. And there is one Lord, Jesus, the Anointed One, through whom we and all things exist. But not everyone has this revelation. For some were formerly idolaters, who consider idols as real and living. That’s why they consider the food offered to that “god” as defiled. And their weak consciences become defiled if they eat it.
