Thanks dude, sometimes I write like that for conspiracists.

Ezekiel 37:15-28 prophesies that two houses of Israel and Ephraim will be united in the hand of God. The two-house movement interprets that as saying all real Christians are genetically Israelite and this will be revealed as part of the unification (similar to British Israelitism). Then they latch on to those who are restoring Christianity to its apostolic roots (which requires understanding Hebrew thought) and they act like this restoration is a legalist movement like their own. But reconciling anyone to Jesus is always contrary to legalism, because what really happens is we keep Jesus's new law (whatever it is for each of us) by gratitude at his rescuing us.

I also joked that in the past 10 generations it's very likely that very many people have a Jewish/Israelite ancestor, but nobody counts that as being Jewish alone.

John Parsons is very reliable on the subject. Here's Wikipedia, which also quotes Parsons approvingly. It looks like the proponents of two-house have regrouped lately as "commonwealth" theology because the original version may already have been defeated by a resounding agreement from Christians, including most all the Messianics.
