No I don’t.
I think you would view the YHWH worshipping religions under the umbrella of Abrahamic religions as a parallel to viewing the various Jesus worshipping religions under the umbrella of Christianity.
Anyways, we’re talking about Mitt Romney’s view on Mormonism, which he has flatly declared he believes is a Christian religion.
That is indisputable. Which is what makes Focus on the Family a bunch of bald faced liars.
That does not mean that an individual Mormon cannot find a faith in Jesus that He is able to credit by His grace, despite Mormonism.
Even if they took liberties saying “Mitt said” we should try not get caught up in their spirit to invalidate.
