Roper's discussion covers many topics of interest including the pre-mortal existence of Adam, God's foreknowledge that Adam would transgress, the resulting preparation of the Plan of Redemption through the Messiah from the beginning, Adam's baptism, his relationship with God, and his divine destiny (theosis), etc. These concepts do not fit well with a common modern spin on Adam that makes him into a monster who wrecked God's plan of happiness for all of us, but they certainly resonate with several LDS perspectives. Here is one brief excerpt to whet your appetite:
If you've been to the Temple recently, you may note that some Temple-related concepts resonate well with some parts of those ancient Christian texts.
Adam in the GardenRecent studies by Michael Stone, W. Lipscomb, Gary Anderson and others have focused on a set of Armenian Christian Adam and Eve texts. These texts were first published in Armenian in 1898 and only in English in the last several decades.25 These texts discuss the events which took place in the Garden of Eden before the Fall. In one of these entitled, Adam and Eve and the Incarnation, the serpent tells Eve, "God was a man like you. When he ate of the fruit of this tree he became God of all"26 In The History of the Creation and Transgression of Adam, the serpent states, "God was like you, because he had not eaten of that fruit, When he ate it, he attained the glory of divinity." Speaking of devil's words to Eve, Michael Stone, the editor and translator of the recently published Armenian and Georgian Adam and Eve texts observes, "The formulation in our text says not just that humans will become like God (gods)" but also that "God was himself originally human and became divine through eating the fruit."27 This variation on the serpent's words is also found in several later medieval Jewish texts about Adam and Eve.28 In the Transgression of Adam, after Eve partakes of the fruit, Adam asks her, "Why have you eaten the fruit?" Eve responds by saying, "The fruit is very sweet. Take and you taste, and notice the sweetness of this fruit" but Adam refuses, saying, 'I cannot taste it." According to this particular account Eve the begins to cry and beg Adam to eat and "do not separate me from you." After some deliberation (three hours according to one account) Adam reasons, "It is better for me to die than to become separated and detached from this woman." Then he partakes of the fruit as well.
These and other extra-canonical texts indicate that after the redemption of Christ that Adam would be taken to paradise and that after the resurrection he would be restored to his former inheritance which he had lost at the Fall. The significance here is that Adam's restoration to his pre-mortal inheritance, where according to these texts he once reigned under God as a king and at God's specific command was even worshiped by the angels, suggests a return to a state where he could again receive such adoration, a state clearly suggestive of deification. The theme of deification in fact is explicit in the Syriac Testament of Adam. There Adam explains to his son Seth that God would eventually fulfil Adam's desire for deification. Just before being cast out of the Garden, the Lord tells him, "Adam, Adam, do not fear. You wanted to be a god; I will make you a god, not right now, but after the space of many years."
For your sake I will taste death and enter into the house of the dead.... And after three days, while I am in the tomb, I will raise up the body I received from you. And I will set you at the right hand of my divinity, and I will make you a god just like you wanted."*
