In this lesson about "The Foundations of Halacha and Aggada", students will engage in a unit exploring various definitions of Jewish community. They will study both classical (Biblical and Rabbinic) texts and contemporary materials to consider ethical problems raised by living in community. These include ethical speech (leshon ha-ra and tochecha) and accepting differences. Students expand their understanding of the Jewish community or communities in which they participate, and discuss what responsibilities membership in a community entails. This lesson allows students to compare and contrast their Jewish communities with less familiar ones. They uncover several different ways of understanding what it means to participate in a Jewish community.
