Meyer has gone on record saying she didn’t insert any Mormon details purposefully, but it’s clear she did write through her worldview — a pretty standard writer practice. In the books, Bella avoids coffee, tea, alcohol, and tobacco, and she mentions the Mormon belief that humans can become divine and later get resurrected.
It is, however, worth mentioning that the whole franchise is fiction and that it is by no means a realistic depiction of the Mormon faith or lifestyle.
The “Twilight” Series Takes from Mormonism
“Twilight” author Stephanie Meyer is herself a Mormon and used the idea of the “celestial marriage” to inform the book. “Celestial marriage” is the idea that once a man and woman are bound in Earthly marriage, they're bound together forever in the afterlife as well.
The characters in the “Twilight” series act with Mormon morals (vampire issues aside). The connection comes when Bella and Edward are married, and Bella starts to die, forcing Edward to turn her into a vampire. Now, the couple is together forever — though in a different way that the LDS Church talks about, of course.
More “Twilight” Mormonism
Well, almost. There are a thousand tiny things you could look at in the extended “Twilight” series that point at Mormonism. One of them is the element in the series called imprinting — something that the werewolves in the series undergo.
Imprinting is when they see the perfect person for them — they are immediately enthralled with that person. It's impossible for them to ignore their feelings. Many believe that this idea of soulmates comes from Mormonism. However, the idea of soulmates isn't part of the doctrine.
Native Americans and Middle Eastern Travelers
According to LDS Church beliefs, members of the greater Abrahamic family — or biblical families related to it — traveled from the Middle East to the Americas by boat around six hundred B.C. They separated into four groups, named for their patriarchs: Lamanites, Jaredites, Mulekites, and Nephites.
The Lamanites gained the greatest power after destroying the others once they fell out of favor with God. They are thought to be the ancestors of the historical Native American tribes.
Jesus Appeared to Native Americans
According to the Book of Mormon, the settlers who moved from the Middle East to America began a war, and that was when Jesus appeared to them. He helped set things straight, though the faulty humans, of course, continued to war. These American groups grew into different races.
Not only does this include Native Americans, but also the Polynesian peoples and those of Southeast Asia. The LDS Church often pushes for good treatment of Native American tribes, in essence believing them to be their forefathers and an important part of their faith.
