In this video series, I argue for the theses that (1) Many different cultures are described in the Bible (2) each culture described in the Bible practised a very distinctive type of marriage, and (3) God respected, endorsed, and confirmed each of these types of marriage. The upshot is that marriage isn't defined by God, rather, God (as described in the Bible) delegated the definition of marriage to human societies and respects that definition. On a Biblical view of things, therefore, the institution of Marriage is not a religious institution, rather it is a secular institution.
In this series, I want to read the Gospel of Mark, as through the eyes of an Atheist who lived in Rome, circa 50AD. What would this Gospel have sounded like? What does it sound like when we don't have Matthew, Luke, and John, or the rest of the New Testament to compare it with?
