For some time, the Mormons have been availing themselves of material in the Fathers of the Church regarding theosis in order to render their own doctrines more plausible. There is no shortage of LDS blogs and websites that exclaim with glee that the LDS doctrine of exaltation is within the bounds of Christian teaching on the basis of the Orthodox doctrine of theosis....
What I wish to look at here is one of the principle texts brought out by LDS apologists and its argument that Athanasius’ doctrine of theosis is inconsistent with his doctrine of creation ex nihilo. This claim has become quite common among Mormon apologists and it is well suited to demonstrate the coherence and strength of the Orthodox position.
The specific text is a doctoral dissertation by Keith E. Norman entitled, Deification: The Context of Athanasian Soteriology. It is available in both print and electronic form. The dilemma so far as I can tell from Norman’s text is that if we are to be deified, then we cannot be created ex nihilo and vice versa. And this is so because things created ex nihilo can’t become deified since by essence, God enjoys a kind of underived existence or aseity. Humans are therefore radically different or “wholly other” than God, so much so that it is impossible to become what God is by essence. Something cannot both be beginingless and have a begining. Deification would entail a natural and therefore essential change in humanity which is precluded by the doctrine of creation ex nihilo. Without such a change, humans can’t be deified and are left in a mutable metaphysical state apart from salvation. The implication is that the LDS can affirm theosis consistently because they reject the doctrine of creation ex nihilo. Therefore LDS theology stands in superior position to the Athanasian and by extension, the Orthodox teaching on deification.
