cofty...
I heard you the first time. Jesus was the exact image of His Father. What we saw and heard from Jesus was representitive of the Father.
Jesus didn't advocate for the things that you mentioned. ("slavery and infanticide and forced marriage/rape") You simply have no evidence to support your claim.
moses represented the IMPERFECT people..God called them "your" people. (as mediator) moses was also an IMPERFECT representative of God to his people.
The OT laws were ceremonial, sacrificial and civil...the civil law was, I believe, tasked to moses. the reason I believe that is because moses took the initiative to change the divorce laws, something he wouldn't have done if these civil laws were from the mouth of God.
Jesus was the PERFECT representitive of His Father to the people and a PERFECT representitive of man to God. Do you see the difference there?
