The Book: A Student’s Guide to Textual Criticism of the Bible
The Author: Paul D. Wegner
It is a very good book. On a scale of 1-5 i would give it a 4. I liked it better than Metzger’s book “Text of the New Testament.”
It was chock full of actual manuscript examples and variants. It discussed how to use the textual apparatus in the NA and UBS. It also had application parts where you could practice choosing the best text for a particular passage.
The cool thing about this book is that it contained both OT and NT criticism in one volume. The downside to this approach is that some of the material was repetitive.
The book definitely takes the side of promoting the Critical Text above and against the Received and Byzantine/Majority Text. I think it is a good idea to get a balanced approach, so i would suggest reading some pro-Received Text and pro-Majority Text materials as well.
