According to Augustine, what's the difference between regenerate life and that before the fall?

In Augustine's four stages of the Christian life, is the Reborn Man in the same state as the Pre-Fall Man? In which state was Christ the man while on earth? [Editor's note: OP refers to the 4 stages mentioned in Augustine's [*Enchiridion*, Ch. 118](https://biblehub.com/library/augustine/the_enchiridion/chapter_118_the_four_stages_of.htm) . [From OP's comment:] The first question is on what Augustine really meant, because both have the same able to sin and able to not sin. The second is an application of the fourfold state. My information and knowledge is based on [this]( http://monergism.com/thethreshold/articles/onsite/four-fold.html) .
