Due to the exile, Jewish civilization ended up splintering off into various sub-groups.
Through this division, Judaism developed a series of "flavors" with regards to common practices and Minhags to each community. The downside of this is we sometimes have cultural conflicts which divide communities from having true universal worship.
Even in a country like Israel, which is supposed to be the focal point of Jewish civilization, the Chief Rabbinate is shared between two different meta-communities (a Sephardic and Ashkenazi Chief Rabbi subdivisions)
Has there been any real push by the various sub-communities to try and bridge the gaps into a new universal center? Or is the topic considered closed off until Mashiach?
