If the nature of the first is that there will be no covenants with others, and the nature of the second is the addition of a covenant, then there is something irreconcilable between the claimed natures.
I am not saying that there is more than one creator, but that the ideas of the divine, that image of the creator, are not synonymous with the image of the creator claimed by the other. There is only one George Washington who president, but if you claim that he was a human, and I claim he was an alien, then the two visions of GW contradict. There still is only one, but someone has a wrong idea about him.
