1 Corinthians 8:4-6

4As concerning therefore the eating of those things that are offered in sacrifice unto idols, we know that an idol is nothing in the world, and that there is none other God but one. 5For though there be that are called gods, whether in heaven or in earth, (as there be gods many, and lords many,) 6But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.
