and for a theist to insist that it is impossible to live a moral life without ritual is false and therefore immoral in itself.
Are you saying that all or most theists insist that “that it is impossible to live a moral life without ritual”?
That would be equally judgemental, unfair and immoral.
Not the same, but similar to saying all Muslims are terrorists.
No, I am not saying that theist individuals insist that “that it is impossible to live a moral life without ritual”. Their books do (with some exceptions). I judge people by the actions. But it is scripture which demands an “exclusivity”, i.e. “only through me shall you have access to god” or “slay the infidel”.
The difference between science books and bibles is that science is subject to modification as we learn more more, while scripture is written in “stone” and not amendable, even as 90% of scripture is based on primitive unscientific thought. The very demand of exclusive adherence to scripture makes them all suspect as to “truth”. They are indeed “dead” scrolls, not living, evolving documents as all other things in the universe are subject to.
They are stuck in time and that time was long ago. Fortunately most people have evolved and have begun to interpret scripture to fit current knowledge.
I fear the fundamentalists, who will defend “their” book to the death and take with them as many non-believers as they can in the process.
