Origen

“ For it is a principle with us, not to worship any god whom we merely “suppose” to exist, but Him alone who is the Creator of this universe, and of all things besides which are unseen by the eye of sense. These remarks of Celsus may apply to those who go on another road and tread other paths from us,—men who deny the Creator, and make to themselves another god under a new form, having nothing but the name of God, whom they esteem higher than the Creator ”

“ In reference to the precept that we ought not to serve two masters, we have already shown what appears to us the principle contained in it, when we proved that no sedition or disloyalty could be charged against the followers of Jesus their Lord, who confess that they reject every other lord, and serve Him alone who is the Son and Word of God. ”
