Problem: Review: An extremely helpful gem on a complex subject of second century religious authority and textual use. For anyone serious about this period and the interelation of cultures, this book is essential. Is it complex and detailed? Of course, it must be to argue the point. Should you buy it? Yes, unless you want to keep running back to the library. I write this only after thoroughly disagreeing with the review above.

Solution:
False
