This is something that I have never been able to understand, so thought I would ask.
It is common that, whenever we look back at previous generations and certain aspects of their lifestyle which would today be considered to be unacceptable, to say something along the lines of, "well, they were a product of their time".
What I personally find intriguing is when we come to those believed to communicate with, and take instruction directly from, a God of some sort.
Often these people are being instructed by God to 'change their ways', other times they are being dictated to, and the individual will write this down in the process of producing a book instructing people how to live their life's.
So if we take the hypothetical example of somebody who either was instructed to change their ways by God, or God dictated a holy text of some sort too, but who also had a child bride.
The argument given is that, while today that sort of thing is not acceptable, at the time it very much was.
But do the religious believe that to be God's attitude at the time as well?
If so, wouldn't that suggest a temperamental God who changes one's mind?
If not, then wouldn't the point where God is directly interacting with a human, either to tell them to change their ways or to dictate a holy text be a perfect chance for God to include a part about child brides not being ok (ie. "Don't eat meat on Fridays, and before I forget, don't marry a 9 year old")?
My question is, how do the religious reconcile God appearing to condone activities in the past, which are not considered to be acceptable today?
