I'm not Jewish but do know that strict observance of religious laws is important in Judaism.
I recently visited one of our suppliers in Israel and the hotel and office block had sabbath elevators. The younger techies I was working with thought it was ridiculous but it seemed that pious/observant Jews used it. There was also a planning controversy here in London about making an area an Eruv so that religious restrictions could be avoided.
These didn't seem to just be a cynical way of avoiding the law which applied to everyone else - like medieval popes declaring Beaver to be a fish or that geese grew from barnacles so they could eat meat in lent.
Is there a particular reason that working around a holy law should apparently be considered pious?
edit: Thank you, the question was meant out of genuine interest I didn't intend any offense with "loophole".
My question was really that in Christianity or Islam in not doing something enjoyable or which makes our life easier on Sabbath, or fasting, it is the sacrifice that is the offering/prayer. Is Judaism different? If you can't start a fire to keep warm the discomfort is the sacrifice, but it is ok to have a non-Jew make one for you, or today have the heating pre-programmed, it seems that the observance of the law is more important than the spirit.
Is the intention of the law in Judaism different from the other two or is it just a tradition that has grown up over the generations?
