Is Mormonism a cult? Yes, no, maybe — who cares? From a Jewish perspective, you could say that Mormonism is simply one of the more recent additions to a very long line of cults. From an atheist perspective, it’s cults as far as the eye can see.
But from a moral perspective, contemporary Mormonism is squarely within the Judeo-Christian tradition, promoting decency, self-restraint, family values, etc.
The old Moral Majority had its flaws, but its core mission was admirable: to promote moral unity under the banner of theological pluralism. However you worship, if you shared the same “traditional values” you could work together. Jeffress turns all that on its head.
