Here we differ. I believe the Commandments, the Beatitudes, and many teachings are not only testable, but are meant to be tested. Blessed are the peacemakers... is one. Putting God first is another.
Ok I'll bite.
I'm curious how do you select which of the things that are said are testable and which are not since you said, "many teachings" and not all. What teachings can you dismiss in your worldview?
let's test.
- You shall have no other gods before Me.
This one is about God being jealous of other religions. It's the bases for religious strife.
2.You shall not make for yourself a carved image.
This one is because the particular religion that was practiced by the Israelites had idol worship. It was the cause for the reformation and one of the most destructive wars in history.
3.You shall not take the name of the Lord your God in vain.
This one shows again how petty God is. He's the almighty but somehow insulted by little old me. Also, a free speech issue.
4.Remember the Sabbath day, to keep it holy.
Let's forget for a second that there's disagreement among the Abrahamic religions about what day the Sabbath is but it's a bit silly in my opinion.
5.Honor your father and your mother.
In my personal experience respect is earned not given. This includes parents who can run the gamut from good all the way to cruel. Honoring people who harm you is not good advice.
6.You shall not murder.
Finally, one I sort of agree with. Although I will say I don't think it's wrong to defend myself but in general good advice.
7.You shall not commit adultery.
Love and lust are universal but can also be fleeting and in general. Staying with someone just because is dumb. This also is the basis for a bunch of laws that to this day create suffering especially among woman across the globe.
8.You shall not steal.
Unequivocally agree. Finally, good advice.
9.You shall not bear false witness against your neighbor.
Again agree.
10.You shall not covet.
Well I guess, god is a Socialist. Because this is the basis of Capitalism. I don't have a serious issue with the principle, but just interesting to note.
So, I did what you asked and tested the 10 commandments. Their usefulness varies from good advice, trough petty, to sometimes useful, trough terrible advice.
The Beatitudes are a bit better, in general more harmless but one is objectively wrong.
3.Blessed are the meek, for they shall inherit the earth.
Human history shows that being meek doesn't get you to inherit the earth, instead it causes you to be exploited, conquered and enslaved.
So again, when the test is run it's shown that the objective evidence shows mixed results.
Your own suggested framework speaks against religion when applied to objective truth as often as not. What does that tell you?
