It has been argued that Judaism can be seen not only as a single religion, but as a group of similar religions. It has also been pointed-out that through all the trials and tribulations that Judaism has suffered through, that there have been common themes that have proven unyielding. Any institution with roots as ancient and varied as the religion of the Jews is bound to have a few variations, especially when most of its history takes place in the political and .
theological hot spot of the Middle East. .
The aspects of Judaism can be examined through Pre-Diaspora Judaism and Post-Diaspora Judaism, primarily in the three temporal subdivisions labeled the Tribal / Pre-Monarchy .
Period, the Divided Monarchy, and the Hasmonean / Maccabean and Roman Era. Among all the time periods where the religion has been split, these three seem to be the most representative of the forces responsible. .
As for a common theme seen throughout all Judaists, the area of focus is the place associated with the religion : Jerusalem a place to call home. No other religion has ever been so attached to its birthplace as Judaism. Perhaps this is because Jews have been casted out and restricted from this place for most of their history. Jerusalem is not only home to Judaism, but to the Muslim and Christian religions as well. Historically this has made it quite a busy place for the various groups. Jerusalem is where the temple of the Jews once stood. The only place on earth where one could leave the limitations of day to day life and get closer to God. In 586 BC when the temple was destroyed, no Jew would have denied Jerusalem as being the geographic center of the religion. From that point on, the Jewish people have migrated around the world, but not one of them forgets the fact that Jerusalem is where it all began. It is truly a sacred place, and helps to define what Judaism means to many people; a common thread to run through all the various splinters of the religion and help hold them together.
