Judaism has faced persecution throughout history but its followers have remained strong in their faith. Some key aspects of Judaism include the patriarchs Abraham and Moses, the building and destruction of Temples in Jerusalem, sacred texts like the Torah and Ten Commandments, the nation of Israel as the spiritual center, and different sects like Reformed, Conservative, and Orthodox. Judaism also observes important holidays and practices like bar mitzvahs, while continuing to transform itself today through universalism and new roles for women while carrying on traditions.
