Two men are stranded in the desert. One man has water, while the other has none. There is enough water for one man to make it to safety. However, if they share the water, they will both die before they could get to safety. What does the man with the water do?
The rabbinical answer is that the man with the water should take the water to save his own life. Of course, the Christian answer is that the man with the water should give it to the other man and give up his own life. I discussed this specific example with my Jewish supervisor, who is married to a rabbinical scholar. Apparently, it made quite an impression, since the topic was discussed by the husband and wife, who reported their conversation back to me. When confronted with the differences between Judaism and Christianity, both thought that Christianity took the higher moral ground.
