Author Bruce R McConkie of the work Mormon Doctrine, which is accepted in most all mormon seminaries is a third party publication.
secondly,
the author of the mormon book "the church and the negro " thanks staff of BYU for helping him with the work. So you would have to disqualify many many mormon books, and BYU by this rule.
again bookcraft is the holder of one of the books "Mormon Doctrine."
and lastly all these books were purchased through mormon bookstores locally.
in conclusion, I will include a scan with a brief quote from the book that in fact quotes the founder of the Mormon Churches:
View attachment 166105
This is one of those quote which is always taken out of context
“Elder Hyde inquired the situation of the negro. I
replied, they came into the world slaves, men- The pro h t ,
tally and physically. Change their situation view of the
with the whites, and they would be like them.
They have souls, and are subjects of salvation. Go into
Cincinnati or any city, and find an educated negro, who
rides in his carriage, and you will see a man who has risen
by the powers of his own mind to his exalted state of re-
spectability. The slaves in Washington are more refined
than many in high places, and the black boys will take the
shine off many of those they brush and wait on.
Elder Hyde remarked, "Put them on the level, and they
will rise above me." I replied, if I raised you to be my
equal, and then attempted to oppress you, would you not
be indignant and try. to rise above me,…
Had I anything to do with the negro, I would confine them by strict law to their own species, and put them on a national equalization.
Because faith is wanting ……Faith has been wanting, not only among the heathen, but in professed Christendom also, so that tongues, healings, prophecy, and prophets and apostles, and all the gifts and blessings
have been wanting…. “
I take it to mean that because we as men lack faith in Christ we will never treat each other with the Christ like love we should.
