1.You shall have no other gods before Me.
As there is no evidence it exists that is totally unreasonable.
2.You shall not make idols.
Why not?
3.You shall not take the name of the LORD your God in vain.
Why not, as again there is no evidence it exists.
4.Remember the Sabbath day, to keep it holy.
I am a non believer
5.Honor your father and your mother.
I would only give them respect if they deserved it.
OK, Floo, you argue on the basis that you don't believe in this God. It should be remembered that the Commandments were given to a people who did believe in his existence, and had good reason to do so - their experiences of him.
So, your argument is somewhat moot, and since it is your opinion, I'm not really sure that there is any need to argue against that, since you have provided us with no evidence for your opinion whereas others have, over the years, provided evidence for their opinion that he does exist.
However, I'd also suggest that since these commandments were and remain the bedrock of Jewish social cohesion, the latter 5 are dependent upon the validity of the first 5. If the first 5 don't stand up, why should the second 5?
[/b]6.You shall not murder.
7.You shall not commit adultery.
8.You shall not steal.
9.You shall not bear false witness against your neighbour.
10.You shall not covet.
Commandments 6/10 are valid.
On what basis do you suggest that these are valid?
