There are atheist Jews and believing Jews, Israeli Jews and Jews of other nations. There is Sephardic Judaism, Ashkenazi Judaism, Mizrachi Judaism and Falasha Judaism. Reform, ultra-Orthodox or Reconstructionist Judaism. Because Judaism is not only a religion, nor a lineage, nor a nation... but then, what is it? These pages shed light on the first monotheistic religion organized around the temple of Jerusalem, a fact that coincides with the writing of most of the biblical texts. They coexisted with Egyptians, Babylonians, Phoenicians or Sumerians... and when these peoples disappeared, the Jews continue to exist. Their culture, language, laws and religion have remained intact even after being expelled from their homeland and dispersed throughout the world. During their exile they developed special rules for living through rabbinical works, such as the Talmud, which provided them with a moral compass to live by, no matter where they ended up.... Even the Holocaust failed to decimate their faith.
