Query: It's not called the green monster for nothing.

When I had Dr. Erickson for Systematic Theology in seminary the cover of this book was green and it was affectionately referred to as "the green monster." It was big and intimidating. I bought the book and began my forced, daily readings of it. I found that this monster was gentle and fascinating. Dr. Erickson covers all the sides of the doctrines he discusses and yet does not fail to define where he falls on them. His writing style is such that he is able to make the deepest issues understandable for anyone willing to put a little time into the book. While, the book is not the book I would recommend for someone with no previous theological reading, it is one that I would say needs to be in the collection of anyone seriouesly interested in systematic theology.
