While I do not believe Jesus would be an advocate for slavery today, I do believe that the presence of the passages are sufficient enough that the Southern Baptist Convention should have kept its nose out of this fight.
It would be merely a small step over thin line for Obama to denounce all Christians as being a "radical extremist" group supporting slavery based on their own teachings.
One purpose of those passages, I think, is that Jesus was showing he was a spiritual warrior; not a social justice warrior. So much of organized religion has tossed the spiritual warrior overboard that the SJW is all they have left. Sadly, the SBC has shown they’ve joined that crowd with this action.
