All Jewish peoples have their own distinctive form of Judaism and it would not be intellectually honest to claim that Median Judaism is a single religion. There has been so much divergence, developments and geographic separation since the Assyrian deportations 27 centuries ago. Median Judaism is truly a world religion or rather a series of historically interrelated religions around the world. To be honest, the Southern Jurisdiction of Judah has also developed beyond recognition since it divorced from the Northern Jurisdiction of Israel in 930 BCE. Religion is living organism in constant state of change and development and the broader Judaism is no exception.
With mass Aliyah of tens of millions of Median Jews from the Middle East and around the world will Israel become far more religiously diverse than at present. This will be a challenge in rather than until now building a nation with one religion will it be a challenge of uniting a nation of a series of historically interrelated religions and from this form one united Hebrew nation.
