References for 1 Corinthians 8:4
For even if there are so-called gods, whether in heaven or on earth-as there are many "gods" and many "lords"-
yet for us there is one God, the Father, from whom are all things, and we for Him; and one Lord, Jesus Christ, through whom are all things, and we through Him.
