Whose Torah?: A Concise Guide to Progressive Judaism

I mostly enjoyed this. It was a quick read and while it is a little dated now, I thought it did a good job talking about how things have gotten more progressive and how each movement has evolved.

But.

There is a single line of semi-acknowledgement in it that I think is probably going to make people throw it in the trash. And maybe that's why I don't see this book on any reading lists when it otherwise was great?

Hint: It's about Messianics.
