The Dangerous Lie Behind Mormonism’s "Brotherhood" of Jesus and Lucifer

In recent years, many have been drawn in by the friendly, family-oriented appeal of the Church of Jesus Christ of Latter-day Saints. But beneath the polished image and wholesome branding lies a theology that strikes at the very heart of biblical truth—starting with the outrageous claim that Jesus Christ and Lucifer are spirit brothers.

This isn’t a fringe belief. It’s fundamental LDS doctrine: that God the Father created both Jesus and Lucifer as His spirit children in a premortal realm. Jesus chose obedience and became the Savior; Lucifer rebelled and became Satan. On the surface, this may sound like a dramatic morality tale of agency and consequence. But in reality, it’s a theological train wreck—and a direct assault on the gospel of Jesus Christ.

The Bible tells us plainly that Jesus is not a created being. He is eternal. “In the beginning the Word already existed. The Word was with God, and the Word was God” (John 1:1, NLT). He didn’t become God—He is God. Co-eternal with the Father and the Holy Spirit. Creator of all things, including angels. And yes, Lucifer is just that: a fallen angel. A creature. A rebel who was cast out of heaven—not the spirit sibling of Christ.

Equating Jesus with Satan in any familial sense is not just mistaken—it’s blasphemy. It drags down the holy Son of God to the level of a created enemy. It confuses the roles of Creator and creature, Savior and deceiver. It’s theological sleight of hand that undermines the uniqueness and majesty of Christ.

Even more troubling is the LDS idea that Jesus “attained godhood” by obedience and faithfulness, and that we can do the same. This, too, is a recycled lie from the Garden of Eden—“You will be like God” (Genesis 3:5). It's not just unbiblical; it’s deadly. God says in Isaiah 45:5, “I am the Lord, and there is no other; apart from me there is no God.” There is one God in three persons—Father, Son, and Holy Spirit. That’s it. No one else will ever qualify.

The LDS framework twists the biblical doctrine of adoption. While Christians believe that those who receive Christ are adopted into God’s family (John 1:12), Mormonism teaches that all people are already literal spirit children of God—co-eternal intelligences placed into spiritual bodies. That’s not adoption—that’s mythology. The “brotherhood of all” may sound inclusive, but it quietly strips Jesus of His divinity and redefines our relationship to God in deeply unscriptural terms.

In the end, this isn’t about nitpicking theology. This is about which Jesus you trust. Because only the real Jesus can save you. The Jesus who is God—not the one who supposedly became God. The Jesus who created Lucifer—not the one who grew up next to him. The Jesus who saves by grace—not the one who shows you how to become your own god.

So let’s be clear: the Mormon Jesus is not the Jesus of the Bible. The Mormon gospel is not the gospel of salvation by grace through faith. And the idea that Christ and Satan are brothers is not just wrong—it’s heresy.

Christian readers: don’t be fooled by the language of love, family, and light. Test all things. Cling to Scripture. And when someone presents a “Jesus” that doesn’t match the Bible, have the courage to say what it is: a false Christ.
