1 Corinthians 8:7, 10

However, not all believers know this. Some are accustomed to thinking of idols as being real, so when they eat food that has been offered to idols, they think of it as the worship of real gods, and their weak consciences are violated.

For if others see you—with your “superior knowledge”—eating in the temple of an idol, won’t they be encouraged to violate their conscience by eating food that has been offered to an idol?
