This excellent essay categorizes the types of needs that religion fills and then ranks the faiths of the world by how “developed” they are, i.e., by how many of these categories they fill and how completely. (In his terms, “developed” is not the same as “true,” not necessarily). He concludes that Buddhism and Christianity are the most developed religions.
He then argues that Christianity is more developed than Buddhism. His argument is the same as my argument for why Christianity is superior to Buddhism. Buddhism offers surcease from pain and desire whereas Christianity offers transcendent meaningfulness of pain and fulfillment of desire.
But in many ways I would argue that Mormonism, in some of its possibilities, refines and develops even what Christianity has to offer. Deification, eternal families, the weeping God of Mormonism, all combine into a world view that is of the most sublime.
