Today there are three main kinds of Judaism: Reform, Conservative, and Orthodox Judaism. There are also kinds with a smaller number of people, such as Reconstructionist Judaism, and Karaite Judaism. Each group has its own practices according to how it understands the Jewish laws. For example, Reform (also called Liberal or Progressive) Judaism encourages people to choose the ways to be Jewish that mean the most to them based on the traditions. Reform Judaism teaches Jews to focus on the ethical laws of Judaism. Conservative Judaism developed after Reform Judaism. The leaders of Conservative Judaism felt that Reform Judaism was too radical. They wanted to conserve (protect) Jewish tradition instead of reforming (changing) it. Orthodox Jews do not believe that Reform or Conservative Judaism are correct because they believe that the laws given by God are timeless, and can't be changed.
