If we can set aside the six-day creation doctrine, we have asserted our supremacy over Scripture. Our mind and our convenience now have a higher authority than the Bible, so that we have denied its authority totally and asserted our authority instead. If we claim the right at any point to set aside Scripture, we have established ourselves as the higher authority at every point. Clearly, therefore, the question of authority is at stake in Genesis 1: God or man? Whose word is authoritative and final?
