The Crescent and the StarAn Exploration of Judaism and Islam. In the world today, there are 1.4 billion Muslims. They live throughout the world—some live in peace and others are at war. But who are they? And how do they connect with us? In this class we will explore the basic story of Islam and its roots in Jewish tradition. We will learn about Islamic holidays and law and how they are similar to ours, but also contain crucial differences. Finally, we will compare the respective missions of these two Abrahamic faiths.
