Most people I know believe Messianic Jews to be a tiny, insignificant minority of Jewry. These same believe the opposite about Christians, that they are a very significant minority if not an occasional majority. Let's look at the numbers.

Barna found only about 4% of Americans hold a Biblical worldview. It would seem pretty easy to see that percentage shrink when scaled for the whole world, considering America is a "Christian" nation.

Wikipedia (the bastion of knowledge that it is </sarcasm>) says about 2.5% of American Jews are Messianic. If we assume all Messianic Jews hold a Biblical worldview (a reasonably arguable assumption), that would make 2.5% of American Jews holding to a Biblical worldview. Again using Wikipedia's numbers, that same percentage generally holds for Jewry worldwide.

This means the percentage of Gentiles who hold a Biblical worldview is on par with the percentage of Jews holding a Biblical worldview. Why is this important? They both represent the remnant. They're both Bible-believing. In fact, they're both Jewish, too, one having been born into Abraham's family and the other adopted/grafted. These Bible-believers are brothers and the all-too-common hostility between them (esp. toward the Messianic Jews) is doubly unfortunate.
