From Derek Ouellette of www.covenantoflove.net:

What a powerful statement from a man who is not interested in sustaining “static categories of interpretation” such as Calvinism or Arminianism; neither, it is prudent to add, is he interested in Open Theism. When Brueggemann approaches the scriptures he does not ask, is the God of Calvin here or the God of Arminius or the God of Pinnock? When Brueggemann approaches the Old Testament he asks the question to the ancient Hebrews, “Who do you say that He is?” Sometimes we see the categories of Calvin and sometimes we see the categories of Arminius, this is partly what makes God “unsettling”, because YWHW cannot be made to easily fit into our “static categories of interpretation” – He is too big, and we are too fallible.

Yet it is a fearful road Brueggemann offers, it is a road of discomfort; because in asking the Hebrews and not the Greeks “Who is YWHW?” he finds himself immediately at odds with classical Christian theology.

“In… much classical Christian theology, ‘God’ can be understood in terms of quite settled categories that are, for the most part, inimical to the biblical tradition. The casting of the classical tradition… is primarily informed by the Unmoved Mover of Hellenistic thought… a Being completely apart from and unaffected by the reality of the world” [p.1]
