The Pharisees were largely responsible for the form of Judaism that exists today, so it is not surprising that Judaism still seeks loopholes in its many added Sabbath restrictions. For example, a visitor to an orthodox Jewish hospital on the Sabbath may find that the elevator automatically stops on every floor so that the passengers can avoid doing the sinful “work” of pushing an elevator button. Some orthodox doctors write out prescriptions in ink that will vanish in a few days. Why? The Mishnah classifies writing as “work,” but it defines “writing” as leaving a lasting mark.
