The Ten Commandments are in the Bible, in the Old Testament.

But they do not have the universal meaning or statement that the Church in particular ascribes to them. For...

[¹] Jesus strictly limited his group of the saved to the Jews, in this respect he stood in the Old Testament tradition, he demonstrably did not know any other. "Thou shalt not kill", referred exclusively to Jews. Rather, it meant quite specifically: Thou shalt not kill Jews. All the commandments that speak of your "nearest" or "your neighbour" contain the same exclusivity. "Neighbour" means fellow Jew.

1st Commandment "Thou shalt have no other gods beside me".

As Richard Dawkins states, among other things: ... "Last but not least, the first commandment already violates our constitution and the general human rights (principle of religious freedom). No one has to dictate to me whether - and if so, how many gods I should worship"....

5th commandment

"You shall not kill"

Immediately after telling the Israelites not to kill, he commanded them to kill. The Israelites were to go to war against the Canaanites to kill everyone, "including women and children and cattle.

In the context, "Thou shalt not kill" therefore only means: "Thou shalt not kill members of your own clan". This is what God meant at that time, this is how he practised it, he never had any problems with the enslavement and murder of non-Israelites throughout the entire Bible.

Even if, for example, today soldiers go to war with Christian accompaniment or church blessing to kill. Here too, they are not to kill their "brothers in faith", but they are to kill the enemy. The latter instruction obviously also applies to believers of other religions, such as the "warriors" of Islam.

Note (however): In order not to want to kill, no one needs a religious "motive".

But realistically speaking, the general rejection of killing is, in the truest sense of the word, an unnatural, sometimes fatal "abstraction". Killing is obviously part of life and can be "helpful". Life is selfish. The predator kills to live and feed its family. Related to our mostly predator-free human world, think of spree killers, for example. Killing a spree killer is the surest "way" to prevent further victims.

9th Commandment

The ninth commandment "Thou shalt not make unto thee any graven image of me [thy God]" serves only God's self-interest and violates freedom of expression and art. Consequently taken to its logical conclusion, it even prohibits any concrete theism, i.e. also the beliefs of Judaism and Christianity, both of which draw a very concrete picture of a personal, omnipotent God.
