Bobcat,
re: "First, (in case you did not know) the Jewish day ran from sundown to sundown. (approx 6pm to 6pm)"
I don't see the relevancy. Please explain.
re: "Fri, 3pm Jesus dies and buried before sundown.
Your comments are based on a 6th day of the week crucifixion, but nowhere does scripture state that.
re: " With our modern time keeping and dependence in life on precision in our time keeping, this appears to us to be an egregious mis-counting of time."
Why mention today's time keeping? We're talking about the first century.
re: "But to Jesus' listeners (with not a single watch or calendar among them)..."
They didn't need a watch or calendar to tell them when it was daytime or night time.
