Joseph was utterly alone in the Christian world in promulgating each one of those five ideas, with one possible exception. Those ideas being that-
 we believe God’s heart beats in sympathy with ours; that
 we lived with Him as pre-existent beings; that
 life is not a fall, but an ascent; that
 God has the capacity and the desire to save the entire human family (shared by some Universalists of the day); and that
 heaven is a perpetuation of those relationships we cherish here and now.
Now any one of those five ideas is sufficiently compelling, I think, to attract adherents, but put all five together and you have a unique combination that had no contemporary parallel. And I’m not surprised, that with those five doctrines at the core, that there have been few dissenters, once you embrace that original mosaic.

A few years ago at the time of the scandal relating to Mormons baptizing Holocaust victims, I was interviewed by a Jewish radio host in Philadelphia. And his first question was direct and to the point. He said, “What are you doing baptizing my dead ancestors?” And, Mormons tend to be very uncomfortable with the doctrine of baptizing the dead. It seems weird, and it conjures up gruesome or rather strange images in the mind, and we tend to avoid that topic. But what I said to this radio host on that occasion was, “Well, Mormons believe in a Heavenly Father who wants to save the entire human family. And at the last day will provide a wedding feast to which He wants His entire human posterity invited.” And I said, “Mormons see ourselves as putting everyone’s name on the guest list. And not everybody has to attend, but we feel everybody should be invited.” His answer to me on air was, “What a beautiful idea. How do I get my name on your list?” Now, that explanation isn’t always going to elicit that response. But that is an example of the fact that our theology is much more powerful and compelling and morally appealing than we have recognized, and I think we need to lead with that more often.(Terryl Givens, "Exclusive Interview with Terryl and Fiona Givens with the release of Terryl’s new book, ‘Wrestling the Angel’", Oct 8, 2014)
