Interesting, don’t you think, that these new ‘Israelites’ are fleeing Christianity?
As these emerging christians came into these Messianic truths it was just a natural progression to see and understand the House of Israel and the House of Judah. 2 nations, 2 peoples, 2 destinies.
More accurately, they are fleeing a synergistic mixture of Christianity and pagan beliefs. That being said, there have been more than a dozen mass conversions of Christians to Judaism in history — including in places as diverse as San Nicandro, Italy in the 1940s (http://en.wikipedia.org/wiki/San_Nicandro_Jews), southern Russia in the 18th Century (http://en.wikipedia.org/wiki/Subbotniks), and rural Peru over the past two decades (http://en.wikipedia.org/wiki/Inca_Jews).
