This book is pretty good in addressing how confessional Lutheranism benefits from Scholastic Lutheranism through critical appropriation of Neo-platonism, Aristotelianism, and Aquinas, which are used to in relation to classical theism, natural theology, participation theology, and how their concepts are used to explain ordo saltis, justification, and sin.
Jordan Copper compares scholastic-Lutheranism approach with the radical-Lutheranism theologians who reject the scholastic approach which resulted them in having very different views on various theological issues. Cooper also gave a concise summary on various philosophers such as Albert Ritsch, Scheleimatcher, Immanuel Kant and etc, on how their philosophical worldview, assumptions and methodology affected Christian theology. I can see how most of these issues are still quite relevant within the Reformed scholarship, where scholars can be quite anti-natural theology, anti-philosophy, anti-metaphysics, pitting pietism against doctrines, pitting biblical theology against doctrines and so on.
Overall this book is pretty good, but it can be very dense in historical theology covering so many figures and concepts. Plus this book in my opinion is not very well organized and there is a lack of subject index, so it can be quite difficult to search for info on the same related topic. And Cooper tends to bit repetitive. Personally, I think this book could actually be organized much better.
Nevertheless, despite the above issues, I still think this book will be beneficial especially to those who want to learn more about theology and philosophy. If you are from the mainline denominations, such as Anglicanism, Presbyterianism, Methodism, and Lutheranism, and if you also agree with the doctrinal statements of these mainline denominations, you will likely agree with almost everything Jordan said here.
By the way this book reads more like a historical theology more than a systematic theology book. And that's fine with me.
