Could you please elaborate on the "Hellenized antiquity?"
I have long believed that there is, at that point in time, a very important philosophical milestone for the development of Christianity as well.
In that issue, there was an article about whether Sufism existed before Islam or not, and that is where I discovered that Sufis will give you different answers depending on whether an Islamic cleric is present. Those Sufis who maintain that their faith pre-existed Mohammed claim an origin point common to the Greek mystery cults and the Kaballah.
This opens up tantalizing possibilities for those who wish to go beyond the Bible and the Koran and enter the world of religious anthropology.
