Perhaps you need to reread this
And if any man speak a doctrine which contradicts what is in the standard Church works, you may know by that same token that it is false and you are not bound to accept it as truth."
mcconkie spoke/taught doctrinal materials, heavly citing mormon canon - there is no excuse - he is a false teacher by mormon definition. The SECOND edition went out under the GA's blessing - their assurance that the doctrines taught WERE correct to those in the standard works. Now the GA then is allowing (since they reviewed and blessed the second edition) false doctrines to be taught.
So much for those living prophets eh?
Oliver Cowdery
Or does it prove there is no time,
Because some watches will not go?
............................................................ Or prove that Christ was not the Lord
Because that Peter cursed and swore?
Or Book of Mormon not His word
Because denied, by Oliver?
A second edition to Mormon Doctrine was created under the guidance of Spencer W. Kimball, who would later become the prophet of the Church. He guided Elder McConkie through the preparation of the second edition to Mormon Doctrine, suggesting approximately fifty changes to make, and Elder McConkie made other changes on his own.
No official doctrine was altered in the book, but the author softened the tone, removed material extraneous to the purpose of the book, and also took out material that was not official doctrine and clarified status on other items.
However, Mormon Doctrine is still not an official source of doctrine and the publisher of the second edition states in the front of the book that it is “a reflection on the times and culture in which it was written” and that it “should not be considered an official statement of doctrine.”
“Bruce R. McConkie was in the positions he held, for the decades he held them, because the Lord wanted him there. He was every bit as much an apostle as anyone else in the quorum. He was called by God and sustained by the church. There is no such thing as a lesser apostle. “Nor is there any such thing as an infallible man, and there may be random errors in Bruce R. McConkie’s writings. He may also have sometimes stepped on people’s toes – inadvertently or on purpose. But he honored his priesthood and he magnified his calling. And he did what he set out to do – he boldly declared the doctrines of the Mormon church.”
Often in his book, McConkie declared the meaning of prophecies from the Bible, or stated his own opinions. Because of his very authoritative tone, which left no room for other opinions, people assumed that everything he said was owned by the Church. Yet, McConkie’s disclaimer is there at the beginning, that this was his own work and his own opinions, and not those of the Church. ~ Mormon wiki
