Written by the late Dr. Hugh J. Schonfield. Re-edited and re-printed by Bruce R. Booker under permission of The Hugh & Helene Schonfield World Service Trust . This is a great book that has been out of print since 1936. It tracks the history of Jewish Christianity since the First Century and why it seems to have virtually disappeared until recent decades - reappearing as the Messianic Movement.
Schofield provides a nice overview of Jewish Christianity/ Jewish Christians after the NT period.
The beginning is constricted through various apocryphal post-NT literature which is interesting. I have read other works where they make this construction.
The best overall part of the book was the detail history of Jewish Christians and their individual histories throughout the Middle Ages. As there was no coherent organized group of Jewish believing Christians outside the mainstream Catholic Church at the time, this history was extremely well researched.
His conclusion is inspiring, as he writes in 1932/33 with the rise of the Nazis but before the official outbreak of the war, that the Land of Israel will rise and that Jewish Christians will play a major part. Inspiring.
Although originally published about 80 years ago, this guy understands the key issues of the Messianic movement today. He also was able to tell some interesting historical stories that are not as commonly told today. Overall, this was a superb book.
