There was a wonderful example of the bible being a poor moral compass in this week's Watchtower study that highlighted Jesus' loving concern for those he miraculously healed.
The account of the man "full of leprosy" brought out an interesting fact about how God directed lepers to be treated. One of the cited scriptures quoting the mosaic law stated that lepers had to live outside the camp isolated from the rest of the population; cry out "unclean! unclean!" if approaching non-lepers; had to tear their clothes; keep their hair disheveled and cover over their mustache. The bible thus commanded the ostracism, stigmatization and humiliation of lepers! How immoral!
But leprosy is actually not a very contagious disease. It is contagious - but not VERY contagious. Thus the dehumanizing ostracism commanded by the law was excessive and unnecessary cruelty. Additionally, leprosy is very treatable today unlike some other diseases. This means that Jehovah could have easily revealed to the nation, some effective medical treatment to be given to lepers. Did he not say that he was making a great nation out of them and surrounding nations would marvel at them? So why couldn't Jehovah have commissioned the medical equivalent of Oholiab? Why couldn't he have revealed effective medical treatments to be used to treat leprosy? Instead he sanctioned their stigmatization and humiliation!
