One thing about God is that He never takes unnecessary steps. Once the circumference of the inside was recored, there was no need to record the diameter of the inside as well since everyone knows that all one has to do to get the diameter is divide the circumference by pi. You don't think that God knows what pi is?
I don't have any concerns in that regard. Your notion of it seems a bit flexible, however: weren't you just recently arguing that the ancients only had whole numbers to calculate pi with?
Um, you mean, like, for instance, creating all the creatures on the earth with one clever evolutionary algoritm, instead of doing the job over and over again, 100s of thousands of times?
If God doesn't take unnecessary steps, why bother with a diameter measurement? You know the thickness of the pot, after all, so you could have calculated the diameter.
If your answer is that humans were doing it, and humans do take unnecessary steps, than I am back to my original question: which parts of the bible are, actually, infallble moral guides, and which are just describing fallible human behavior? And if we're going back to that, than I'll remind you that I still don't seem to have an answer to the question of whether the Golden Rule prevails over a Commandment or vice versa?
