If Elizabeth is still aMormon, she is not a Christian and has not been saved.
I know Mormons believe in some weird sort of unbiblical universal salvation. But only those who place their faith in the finished work of Jesus Christ are saved. There is no other gospel (Galatians1). All the rest are false and will lead to hell, the great white throne of judgment and the lake of fire.(Revelation 20)
Unknown quantities and not for us to judge. I can't figure out why so many are so dang concerned with the souls of the Romneys and not so concerned about the sold they can reach with the Word. For all we know, the whole Romney clan, and even a whole bunch of Mormons, have acknowledged Christ as Lord and Savior and are as saved as the rest of us who either belong to more "traditional" religions (over 32K sects of Christianity and some of them are real doozies) or even non-denominational. I have heard Romney acknowledge Jesus Christ as his Lord and Savior and have no reason to not believe him. I got away from religion because it has so many ways to obfuscate the Word by mixing in a few thousand canons, doctrines, rites, ceremonies, etc., that it really whittles away at the pure carrying of the good news of the Gospels and the New Covenant. The Bible will not make me a theologian, but it carries ample Word to bring me to Christ.
There are a number of "universalist" Christian religions out there and we will never truly know until He comes back. Even the Rapture and its timing have not become "settled science" among all theologians - it makes no difference because it will be what it will be as He spoke it and all we can do is try to be prepared and to carry the Word that others can be prepared too. Carrying the Word itself is much more effective than leaving it out of the equation and just slamming the religions one doesn't like - I don't like any of them and consider them to be purveyors of sinfulness because so many get so caught up in the religion that they start to miss the MESSAGE. I won't go on a crusade against any religion (I love conversations though) because even the worst of the Christian religious sects has undoubtedly reached some souls with the message they needed to hear.
