Not only that, but none of those things are even taught in the Book of Mormon. So you can add to this list of things neither taught in the Bible or BoM:
NEVER teaches that eternal hell or outer darkness is a temporary spirit prison
NEVER teaches anything about a "telestial" degree of the glory -- Smith himself made up the word [and note the BoM says NOTHING about "three degrees of glory"]
Not only is the BoM silent about the degrees of afterlife, but about the alleged Mormon "pre-life" -- the so-called "pre-existence"
And where oh where in the Bible or BoM is it taught that individual family units & marriages are forever?
Oops. Just not there.
(And here the D&C taught that the Book of Mormon was the "fulness of the everlasting gospel" ... looks like it's the emptiness of the perverted "gospel")
Aye!!
There's the rub!
Why doesn't the BoM actually CONTAIN the Restored Gospel®?
