Major Book on the Sonship Controversy

The author of this book was one of my professors at WTS, and is most likely the world’s expert on the doctrine of adoption (sorry, Dr. Beeke, it is not intended as a slight of your excellent book, which, I notice, makes use of Trumper’s thesis quite extensively). The doctrine of adoption, of course, plays a huge role in an orthodox response to the sonship movement. This makes Dr. Trumper extremely well-qualified to write this book.
