1 Corinthians 8:5

However, not all men have this knowledge; but some, being accustomed to the idol until now, eat food as if it were sacrificed to an idol; and their conscience, being weak, is defiled.

For if someone sees you, who have knowledge, dining in an idol’s temple, will not his conscience, if he is weak, be built up to eat things sacrificed to idols?

For through your knowledge he who is weak is ruined, the brother for whose sake Christ died.

However at that time, when you did not know God, you were slaves to those which by nature are no gods.

who opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the sanctuary of God, exhibiting himself as being God.
