Notice the mind reading. I've never heard anyone say Satan was our "Elder Brother", ever.

Lds "apostle" Russell Ballard, circa 2010:

So?? Notice nowhere is the term "Elder Brother" like is used to describe Christ.

We never refer to Lucifer as "Elder Brother" like you claimed. You fail at mind reading.

I said many times that Lucifer is part of the human family and is our brother. So you run off and find a quote that proves me right... cool.

Never? (I guess you just don't speak for all Mormons or Mormon general authorities like you think you do)

I expect a humbling acknowledgement here that you are wrong, or were simply mistaken:

1

“..That Lucifer, the son of the morning, is our elder brother and the brother of Jesus Christ.” (Lds "apostle" Bruce R. McConkie, Mormon doctrine pp.163-164)

Elder Trevor Christensen, who was serving as a Mormon missionary in the Florida Tallahassee Mission. Here's what "Elder" Christensen blogged:

"There was one thing needed, a Savior, an ultimate and eternal sacrifice. Lucifer, or Satan, his name means "Son of the Morning" meaning that he was a very choice spirit of our Heavenly Father, offered himself to be the sacrifice so that all will be saved no matter what, but he wanted all the glory to be his, and not our Father's. Christ then offered himself as the sacrifice and said the glory should go to our Father. Christ is our elder brother, Lucifer is our elder brother, we all are sons and daughters of God, so therefore, Satan and Christ are brothers.
Where'd all the good people go? (Sept. 28, 2009)

Lds "prophet" Spencer W. Kimball, in mentioning the Mormon jesus, cited this jesus as referencing Satan as "his brother" in an official Lds publication...so not sure why the cartwheels on your part to avoid such a reference:

Perhaps his brother, Lucifer, had heard him say when he was still but a lad of twelve: “Wist ye not that I must be about my Father’s business?” (Luke 2:49).
Ensign, December, 1980: Jesus of Nazareth

Never? (Shall I keep going?)

"You will recall that Lucifer, our elder brother, proposed that he should be sent to this earth as our savior."
Marie Fox Felt, The Instructor, May 1941

Here's a Mormon writing online who concludes "The LDS gospel is very different than any other that has ever known to exist. Philosophically speaking it is the only form of Christianity that makes any sense." (So you know he's a faithful Mormon).

In that same July 11, 2012 post, he (Water Dog) wrote:

4) Premortal - Christ our elder brother, Satan also our elder brother.
