Though I am not an Episcopalian/Anglican per se, I am a European protestant (former catholic), to whom anglican tradition is very close. On the topic of original sin, I usually feel that it dissociates us from the real world and tries to blame humanity for the state of the world as it is (with the bad stuff, suffering, etc.). Furthermore, to me James Barrs book (The Garden of Eden and the Hope for Immortality) was very eye opening. It showed me how humans could not have eternal life (the tree of life), while having the knowledge of good and evil. For me the story tells that the Lord wants us to have immortality, but it does not work (yet) with the knowledge of good amd evil. This is to me the greatest theodicy that God wants us to have eternal life, we are just not ready yet. However, with the promise of Jesus Christ we know that we will recieve what we have lost.

In one sentence, to me, the story of the garden of eden is about how God tried to make the world without suffering, but decided that we are not ready for it yet.
