Do Mormons believe Jesus is elder brother to Lucifer?
Yes, and worse! However, their lay people are kept in ignorance of many of the occult practices that are carried out in the Mormon temple, there are many mormon churches but only around a dozen temples. Satan was an angel that fell but the Jesus of the Bible never was an angel, Heb.1:2-6. Their lay people are taught that the temples contain valid proof of the (off) teachings that they are taught – so the lay folks think they could go to the temple and find it – however, those that did go were, of course, disappointed to say the least. They major in the book of Mormon instead of the Holy Bible. They teach that a man has to have many wives to become “a god” (cp. Gen.3). And that their Jesus didn’t atone for all sins, thus, they had taught (some still practice it) blood atonement by one’s own blood in relationship with certain sins, etc. Their head leaders are known to change their teaching (more wool) to try & hide their false & evil teachings – even from their own lay people.
