I finally got around to reading it in full, and I must say I found it rather disappointing. I would rate the volumes individually: vol. 1 = 2 stars, vol. 2 = 3 stars, vol. 3 = 4 stars. In the first volume in particular, Pannenberg relies entirely too much on philosophy and other disciplines. Little is done to explicate the doctrine of God in a way that is relatable and usable. To be frank, much of it comes off as a show of erudition, and unless one is very widely read, practically incomprehensible. Like many others, Pannenberg's writing and thought improves once he moves beyond the doctrine of God and enters other loci where natural theology is less helpful and one is forced to draw more heavily on the Bible and Christian tradition. I found the sections on ecclesiology and eschatology in the third volume to be the best, and in soteriology his discussion of the law and Gospel was excellent. Pannenberg's significance as a great 20th century theologian is undeniable, yet the audience for which it is suitable is rather small. Beginning students of theology should avoid it entirely less they get put off of the discipline of systematics entirely; it will not help them in grasping the basics of doctrine. Likewise, intermediate students are likely to find it of limited value. Advanced ones (read: higher than M.Div.) may find it helpful in researching specific topics in which Pannenberg does an admirable of getting to the heart of issues and provides excellent references, in both quantity and quality, to key primary sources.
