"the old laws was based on a concept of purging and purification to the extreme that was misused by people who were carnal minded. and if your looking at in on a "flesh" level you would only see a man and a helpless sinful woman

but the true parallelism of the man and wife in the old testament is God and the church."

But tell that to the girl that was sold to her husband at age 12 to a man 3 times her age. What you're really saying here is the idea of morality changes. Which is something the church itself likes to challenge with those outside the faith say the same thing.
