The book is essentially a manifesto for postconservatism, a term with Olson essentially coined. Olson defines postconservatism mostly in reference to conservative evangelicalism, which he believes is dominated by theologians that are obsessed with setting boundaries and tightly defining what it means to be an evangelical. Conservatives, he argues, are almost always opposed to fresh theological proposals and operate from a reactionary standpoint towards any revision of classical doctrines.
Postconservatives on the other hand are open to new ideas. They tend to be frustrated with theological systems that confine theology to head knowledge (which consensus has unfortunately labeled 'propositional truth'). Without rejecting the intellectual component of theology, postconservatives want to refocus theology on heart knowledge and our response to God. Postconservatives are more concerned about orthopathy (right experience, referring, I assume, to the need to be 'born again') and orthopraxy (right action) than with orthodoxy (right belief).
One can sense that Olson is frustrated with the reactions he has received from the theologians he has grouped under the conservative banner, including Millard Erickson, Wayne Grudem, D.A. Carson, and J.I. Packer. Olson's tone sometimes conveys the message that he just wants these guys to stop picking on him. Though I agree with him that conservatives often go too far in their reactions against postconservatives, Olson's focus on their differences makes it more polemic than necessary. He lacks the nuance of a postconservative like Kevin Vanhoozer, and draws more fire upon himself as a result. "Some [conservatives] have expressed harsh criticism, if not condemnation... of [another postconservative's] theological project while embracing and applauding Vanhoozer's. The fact is they are very similar." (121) Hey playground bullies, he shouts, shouldn't you be picking on him too! That's not fair!
That is not to say that he is necessarily wrong in his appraisal of the reaction from conservatives. In reference to Open Theism, his observations are right on: "It seems to me that conservative evangelical reaction to open theism has been nothing short of hysterical... All in all, it seems that the open view of God needs much more careful study and dialogue among evangelicals, whereas many conservatives seem to wish to halt study and dialogue and focus energies on drawing boundaries that exclude open theists from evangelical communities." (125-6) Amen.
Olson does a good job of commending postconservative theology, especially to those that are disenchanted with the similarities between fundamentalism and evangelicalism. The book functions as a sort of 'on ramp' to progressive evangelical theology. Or, to alter the metaphor slightly, he effectively draws the map of what he considers postconservative theology. It is no surprise the Yvette recently came away from the book with a massive reading list. Olson marshalls an impressive array of theologians in at least partial support of his program: the late Stan Grenz, Alister McGrath, Kevin Vanhoozer, Henry Knight III, Clark Pinnock, Miroslav Volf, and F. LeRon Shults.
Unfortunately, Olson draws and redraws and redraws the map several times. Readers are re-introduced to Stan Grenz an Kevin Vanhoozer four or five different times. He examines several aspects of postconservative theology in turn, often repeating himself each time. For instance, he mentions Grudem's (inaccurate) list of thirty-four conservative theologians four separate times (pp.9, 21, 173, 188). The book has about 125 pages of valuable information stretched into 237 pages. If he were fun to read (like N.T. Wright for instance) I wouldn't mind so much, but the last hundred pages or so were a chore rather than a delight to read.
The biggest flaw I can see with Olson's view of postconservative theology is that in attempting to straddle between liberal and conservative soteriologies, he ends up falling into a chasm of inconsistency between them. He states, "where right experience (orthopathy) and right spirituality (orthopraxy) are present in Jesus-centered living, authentic Christianity and even evangelical faith may be present even if doctrinal correctness is not yet fully present -- provided that movement in the right direction is clearly discernible." (84) In other words, you don't have to be orthodox to be a Christian, just moving towards orthodoxy. But he provides no reasons for this to be so. If salvation is dependent on an experience with God alone, why assume that such an experience will necessarily lead one closer to orthodoxy? If orthodoxy is an important component of salvation, then why simultaneously deny its importance. Either orthodoxy is necessary or unnecessary for salvation. In this matter, postconservativism has either moved too far from conservatism or not far enough. One senses that this is a vestige of conservatism that Olson is (inconsistently) not prepared to part with. Thus to liberals, postconservatives are still conservative in every sense that matters.
