Several LDS writers today like to indicate-inadequately-that the early church fathers and the Eastern Orthodox Church actually supported their doctrine of humans' becoming gods. But it is important that we be more accurate than these Mormon writers have been. Let's be clear in our research.
Although some early church fathers and Eastern Orthodox have often spoken about a Christian's eternal hope as deification, divinization, or becoming godlike, they are attempting to describe the Christian's future mystical union with the Trinity. They did not believe or teach that humans could become fully equal with God. There is a significant difference between Christian glorification and the human deification taught in Mormonism. Christians teach eternal human glorification, but not Mormon deification.
Christians advocate that through the eternal grace and power of Jesus Christ we will become "like God" through salvation transformation, which is radically different from the Mormon version of becoming "equal to God." Christians are to be people infused with a great future hope in experiencing the glory of God. God has great eternal blessings in store for everyone who puts their faith and trust in Jesus Christ for salvation. Our confident hope is in God; it is a future hope of a life transformed and glorified by God (Titus 3:7). The biblical hope of human glorification is the anchor of our souls (Heb. 6:19).
Christians are clear and resolved. We are created finite humans who worship a one-of-a-kind eternal God, filled with God's eternal hope and power that enables us to escape the corruption of this evil world (2 Peter 1:4). As followers of Christ, we have hearts set on fire with the future hope of enjoying God for eternity, and we look forward to total transformation, as the apostle John declares:
Beloved, we are God's children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is. And everyone who thus hopes in him purifies himself as he is pure (1 John 3:2-3).
Mormon teaching concerning the past human nature of God and future god-potential of humans creates the Grand Canyon divide between Christianity and Mormonism. In contrast with Mormonism, Christianity stands strong in affirming and preserving the total and complete distinction between God and humankind forever (Rom. 1:18-32).
As Christians, we will be "re-created in God's image, perfect in holiness and immortal in nature, with physically resurrected and glorified bodies," but this does not mean that humans take on God's being and unique attributes or the ability to create or redeem. We will receive all the spiritual blessings of God in Jesus Christ as revealed in Ephesians 1:3-14, but this eternal experience will be quite different from functioning in all the powers of God, as taught in Mormonism. It is unthinkable, repulsive, and even blasphemous to Christians for anyone to spread the teaching that humans can become fully equal to the eternal God we worship.
