The growing scholarly corpus on Christian deification stands as a testament to an ever-increasing interest in the topic among academics, which may, in turn, be indicative of a fascination with the idea throughout the general population. While the Eastern Orthodox tradition is best known for embodying this via its doctrine of theosis (θέωσις), and Mormonism is perhaps infamous for its teachings on the matter, recent scholarly contributions have teased out threads of deification in the writings of famous Protestant and Roman Catholic thinkers such as Thomas Aquinas , Anselm of Canterbury , Martin Luther , John Calvin , John Wesley , and Jonathan Edwards . Deification has also been noted in the Anglican tradition . Or in other words, it’s not just Mormons and Greeks having all the fun anymore.
The teachings of Mormonism served as this Protestant’s introduction to the world of deification, and while the broader topic will always interest me, it is the Mormon brand that perpetually seduces me. Although, it may be more correct to speak of Mormon brands of deification, for I have found Mormon thought to be far from homogeneous on the subject. Charles Harrell notes this phenomenon in “This is My Doctrine,” citing two LDS authors who recently distanced themselves from more traditional teachings on Mormon deification. Harrell writes:
In current LDS thought, the idea of human being becoming like God is sometimes marginalized, especially in interfaith dialogues where it continues to be a controversial issue. In his Mormon-evangelical exchange, Mormon co-author Stephen Robinson gives this explanation: “What do Latter-day Saints mean by ‘gods’? Latter-day Saints do not, or at least should not believe that they will ever be independent in all eternity from their Father in heave or from their Savior or from the Holy Spirit. Those who are exalted by his grace will always be ‘gods’ (always with a small ‘g’, even in the Doctrine and Covenants) by grace, by an extension of ‘his’ power, and will always be subordinate to the Godhead.” BYU religion professor Roger Keller conceded at a multi-denominational conference in 2002 that “there will always be a qualitative difference between the Father, the Son, and us.” Thus, although the doctrine of becoming like God is still acknowledged in the Church, there seems to be a growing tendency to explain it in a more traditional Christian sense than in an absolute sense. 
Pushing back against the line of thought described by Harrell, David L. Paulsen insists, “Latter-day Saint tradition holds that there exists no ontological barrier preventing mankind from becoming all that God is and enjoying the same kind of life that God lives, and I have long been puzzled by scholarly claims to the contrary.” 
Observing disagreements amongst Latter-day Saints on their doctrine of exaltation has led me to ask, how did my LDS friends arrive at this point? In what ways has the Mormon doctrine of exaltation evolved since its inception in the lifetime of Joseph Smith, and where is it going? This, in turn, has led to subsidiary questions:
- In what ways has the practice of polygamy been applied to the doctrine of exaltation? Did the abandonment of polygamy starting in 1890 affect teachings on exaltation in the mainstream church? Does polygamy have any bearing on the doctrine of exaltation in contemporary times?
- Have external factors such as evangelical criticism or a desire for greater mainstream acceptance contributed to shifts in teachings on exaltation? What other possible external factors have contributed?
- If the famous couplet states, “As God is, man may become” and God is literally and necessarily male, can women be exalted? If so, is exaltation for women different from exaltation for men? What are the anticipated sexual dynamics between exalted men and exalted women in the celestial kingdom?
- What is the relationship between exaltation and Mormon ordinances such as baptism, confirmation, endowment, sealing, and “the Second Anointing”? In what ways does Mormon temple worship interact with exaltation?
- In what ways does exaltation compare to other Christian teachings on deification, as found in the Eastern Orthodox church, Anglicanism, Wesleyanism, Roman Catholicism, or the works of John Calvin, Martin Luther, Jonathan Edwards, or C. S. Lewis? 
- Do splinter movements from the larger Mormon church such as the Community of Christ, the Fundamentalist Church of Jesus Christ of Latter-Day Saints, the Church of Jesus Christ of Latter Day Saints (Strangite), the Apostolic United Brethren, the Church of Christ (Temple Lot), or the Centennial Park group teach exaltation in any form? In what ways do their doctrines of exaltation differ from that of the mainstream LDS church?
These are questions that I hope to explore in my thesis, and I hope to give you a taste of my answers as I develop them and receive critical feedback from you via my blog posts here at Worlds Without End.
