Religion should have no part in law

Firstly thank you for accepting my first debate, however secondly the claim that there would be no morals without religion is outrageous, If you were to base the law on the 10 commandments, while some are morally obvious, and I say obvious because humans have a natural pack instinct, meaning we want to work together to succeed, that is true if you do or do not believe in any kind of religion. So anything that would be detrimental to that is purely natural morality. http://en.wikipedia.org... The first 4 commandments say nothing about morality and only about serving the "Lord" and interestingly all of these come above what I would argue is the most important "You shall not murder" but that only makes it to #6 #1 You shall have no other gods before Me - Has no bearing on law #2 You shall not make for yourself a carved image - Has no bearing on law # 3 You shall not take the name of the Lord your God in vain - Has no bearing on law #4 Remember the Sabbath day, to keep it holy. - Has no bearing on law and further is blatantly ignored my society and in todays world, ignored by acting religious #5 Honour your father and mother - Has no bearing on law #6 You shall not murder - Now we're getting somewhere, however natural morality as a pack species makes sense why we naturally don't want to kill each other #7 You shall not commit adultery - Based on one report http://downloads.frc.org... shows infidelity is 7.7% for religious vs 15.3% for non religious, noting that infidelity is the next listed to murder on the commandment list it would appear that religious don't treat it all that important with a 7.7% - Adultery has basically been abolished in the 20th century, meaning really has actually no or little place in law #8 You shall not steal - Again this really is a natural morality, if you steal and work by your self it is working against the idea of a pack mentality #9 Not bear false witness against your neighbour - Same as above #10 You shall not covet - Same as above if this really is included depending how you read it. I don't disagree there are a couple of morality items on the list, but they are natural instincts in us, greed is the only element that leads to breaking this. If we're to take other elements of religion (I'll use the old testament here, and point to the fact of slavery, it not only condones it but encourages it, along with the mistreating of your slave. Now really would you have that brought into law? I feel religion has no place in law, there are no specific elements to religion that helps the law other than what's natural morality, unless of course you want to introduce elements from the new testament such as "If a man also lie with mankind, as he lies with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them" if religion really had a true free reign on the law system, look to what extent it could become, that obviously isn't going to happen now, what with society learning more about things like homosexuality, but it does go to show what issues and problems religion has with core understanding of the human race. I put it to you, what religion is and isn't ok to be part of law, is Sharia law ok? and what part does religion really have to play in law in todays society.
