I understand the point you are trying to make-yes. However, you
are mistaken. You can't cherry pick. Some things were applicable to ancient Israel and some are applicable to mankind in general. If you know which is which then you will avoid that cherry-picking mistake. Knowing which is which is a simple matter of becoming
familiar with the book one is using for guidence. One would know, for example, that the stoning you mention is no longer required just as circumcision is no longer required as well as the dietary laws. When they were, they were required of the Jews and not mankind in general.
That is pure assumption on your part.
There is nothing in the book that states "ok, after this date, people don't need to do this anymore. Just assuming that stoning is not needed for adulterers anymore is the same as saying, "I know exactly what god means". Bit arrogant methinks.
In truth, people stopped doing a lot of things that the book mentioned because they discovered it was plainly idiotic and based upon the ramblings of strange superstitious old men.
BTW
What does the theist question have to do with all this?
You mentioned satanists in your post. Curiousity on my part begged an answer as I can't see the difference between a satanist and a theist. They both believe in the bloke in the sky.
