An important background episode with a lot of interesting ideas. Possibly wastes some time defending conventional views that don't need defending.
We look at the good and the bad and the very bad of settled agriculture. After a little Aristotle we move on to the great anthropologists, and their views of family structure and how that interacts with Christianity. We take a look at the Greco-Roman legal context of the early AD period. And how women and widows powered the early growth of the church. We look at very unusual, weird features of Christianity and how those features contributed to early growth. It's all done within the context of the 'package' of Christianity, innovations in monogamy, exogamous families, the end of exposing children, and female consent to marriage. This is valuable background information before we move on to the main historical narrative in Episode 4.
