1 Corinthians 8:5-7

New Revised Standard Version Catholic Edition

⁵ Indeed, even though there may be so-called gods in heaven or on earth—as in fact there are many gods and many lords— ⁶ yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist.

⁷ It is not everyone, however, who has this knowledge. Since some have become so accustomed to idols until now, they still think of the food they eat as food offered to an idol; and their conscience, being weak, is defiled.
