Since there is no way for me to prove one way or another, I
won't go there.
Your assumption is that the patriarchs sinned because they had a
household structure different from what we are more familiar with.
You fail to note that the lifestyle of the Old Testament times are
entirely different from you are used to. It is not considered
adulterous to have multiple spouse in those days. There is also no
commandments for the people of the era to have only one wife. When
the Hebrew people moved towards the times of the New Testament, new
laws were in place and the older laws (culture) were either
outdated or abolished.
If you are going to question the way the OT people live and attempt
to draw similarity, then why stop at marriage, didn't you read the
thread on "unclean" food?
