The Latter-day Saints are frequently accused of believing that they can, at some point in the future, become "Gods." Understandably, to many who do not fully understand our doctrine, the mere idea is out-and-out heresy.
Before we really get started, let's clear up two big, big misconceptions:
(1) We do not believe that any of us will ever be equal to God, our Eternal Father in Heaven. He will always be our God and we will always worship Him.
(2) Nothing we could possibly do on our own could exalt us to the level of deity. It is only through the will and grace of God that man is given this potential. And "with God, nothing is impossible."
We believe, as you may know, that ours is a restoration of the very Church Jesus Christ established during His ministry here on earth. It would follow, then, that we believe we are teaching the same doctrines as were taught then and accepted by Jesus followers. Throughout the New Testament, there are indications that this doctrine (known as deification or exaltation) is not one the Latter-day Saints invented, but that the earliest Christians understood and believed it, as well.
Romans 8:16-17, 2 Peter 1:4, Revelation 2:26-27 and Revelation 3:21 are the four I like best. Through these verses, we learn that, as children of God, we may also be His heirs, joint-heirs with Christ, even glorified with Him. We might partake of the nature of divinity and be allowed to sit with our Savior on His throne, to rule over the nations.
Now, if these promises are true (as I believe they are), what do they all boil down to? To the Latter-day Saints, they mean that we have the potential to someday, be godlike. One of our prophets explained that "we are gods in embryo." If our Father is divine and we are literally his "offspring", as the Bible teaches we are, is it really such a stretch of the imagination to believe that he has endowed each of us with a spark of divinity?
Finally, there is considerable evidence that the doctrine of deification was taught for quite some time after the Saviors death, and accepted as orthodox. Some of the most well-known and respected of the early Christian Fathers made statements that were remarkably close to the statements LDS leaders have made. For example:
In the second century, Saint Irenaeus said, If the Word became a man, it was so men may become gods. He also posed this question: Do we cast blame on Him (God) because we were not made gods from the beginning, but were at first created merely as men, and than later as Gods? At about the same period of time, Saint Clement made this statement: The Word of God became a man so that you might learn from a man how to become a god. And Saint Justin Martyr agreed, saying that men are deemed worthy of becoming gods and of having power to become sons of the highest. Some two centuries later, Athanasius explained that the Word was made flesh in order that we might be enabled to be made gods. He became man that we might be made divine. And, finally, Augustine, said, But He that justifies also deifies, for by justifying he makes sons of God. For he has given them power to become the sons of God. If then we have been made sons of God, we have also been made gods. Even today, a similar doctrine is taught in some of the Eastern Orthodox churches.
Even the noted Christian theologian, C.S. Lewis, said much the same thing in his book "Mere Christianity."
The command Be ye perfect is not idealistic gas. Nor is it a command to do the impossible. He is going to make us into creatures that can obey that command. He said (in the Bible) that we were gods and He is going to make good His words. If we let Him for we can prevent Him, if we choose He will make the feeblest and filthiest of us into a god or goddess, dazzling, radiant, immortal creature, pulsating all through with such energy and joy and wisdom and love as we cannot now imagine, a bright stainless mirror which reflects back to God perfectly (though, of course, on a smaller scale) His own boundless power and delight and goodness. The process will be long and in parts very painful; but that is what we are in for. Nothing less. He meant what He said."
Finally, according to The Westminster Dictionary of Christian Theology, Deification (Greek theosis) is for Orthodoxy the goal of every Christian. Man, according to the Bible, is made in the image and likeness of God
. It is possible for man to become like God, to become deified, to become god by grace.
So, the "Mormons" really didn't come up with this doctrine. We only restored that which had been lost for many, many years.
