Curiously, Joseph Smith, Jr. never said the Book of Abraham was scripture. That was somebody's idea in 1880, when it was canonized.
Don't get me started. The Book of Abraham has been thoroughly debunked by every source in the world - including LDS historians - except rabid apologists who are triple-jointed and intellectually dishonest to suggest it's anything other than a crass attempt to interpret hieroglyphics by somebody who had no idea what he was doing.
It’s not only the Book of the Dead, Smith claimed one of the ‘gods’ (Min) from the text was God. For those unfamiliar with Egyptian pantheon, Min is the Egyptian god with the erection.
Rather fitting considering LDS theology...
