Well if the "seed of Cain" is black, how do we know that Cain wasn't born black? Geez, how do we know that Adam wasn't Black? How do we know that Eve wasn't Black? Where in scripture is their skin color described?
Indeed, how do we know that anyone prior to the flood was White?
Can you name one verse in any scripture, including your own, that says that Adam was white?
And how do we know that the Book of Moses was correctly translasted?
We can check the translation of the bible because we have copies of the translated documents. How does anyone attest to the accuracy of the "book of Moses?"
Does the LDS Church have the original manuscripts? What language was it originally written in. What word in the original manuscript was used to translate the word "black?" Does the LDS Church have any links to its original manuscripts for the Pearl of Great Price?
Also what the heck does that scripture mean? Is god some kind of segregationist? "and had not place among them"
Sounds like bad 19th Century English. What does the original manuscript that Joseph Smith used say? Did Moses use poor English?
