4.5 stars. Essentially, Leithart sets out to answer the question: What is the place of the Church in this world? In the preface, Leithart says it's a fragmented book, and it is, which makes it somewhat difficult to review, but that said, the advantage is that it offers arguments from many directions, achieving with grapeshot what a cannonball can't.
Leithart's argument is that the modern Church has privatised religion by intellectualising and abstracting doctrine, reducing the sacraments to nothing but symbols, and separated the gospel from daily life. This pale and truncated vision of the church he calls Christianity.
The book has five sections. I wish I could take each in turn, but I don't have time for that. First, against Christianity. In essence, the Church is the order of the new creation, the City of God standing opposed to all political and social organisations of man. This means the Church is political, but it is a new political order that proclaims Christ as ruler of every nation, person and institution. This means the Church is not another religion in the marketplace, jostling for its share of the customers. It is a new city, not a religion, reorganising human society and life from the ground up, demanding loyalty to Christ above any other loyalty. Religions do not do this: they allow you to worship Caesar, which is why Christians were singled out for persecution under Imperial Rome: they refused to worship Caesar. A major exception to this rule Islam, as it combines political and religious allegiance. The difference between Islam and Christianity is, however, that the former uses a real sword to conquer the world, while the latter uses the sword of the Spirit, the Word of God to convert the world. And this second sword does not kill, but brings the dead to life. Putting things another way, the Church really is the new world order (secular progressives, in their commitment to globalism also believe in a new world order, but one without Christ). If the Church is a city, it embodies a culture, and thus we cannot talk about 'Christianity and culture'. Culture always embodies religion. "The gospel announces a new creation [complete with a new culture, new regularities, new orders]. The gospel brings nothing less than a new world."
Against Theology: "Theology is always gnostic, and the Church firmly rejected gnosticism from her earliest days." Theology is a problem because it isn't in the Bible, and the Bible is preaching and prophecy, not theology. Theology deals with 'timeless truths', but the Bible deals primarily with real history, real people, real events, commentary on events, and "occasionally, reflections on the constants of life in the Proverbs." This leads to a really big problem: that of separating theory and practice. Theology means we have to separate the theory, and then apply it in our lives. In actuality, "all teaching is application." If theology is timeless truths, then all of life is outside theology, because all our life is temporal, which means that other voices will shape the life of temporalities. "Politics is left to politicians, economics to economists, sociology to sociologists, history to historians, and philosophy to madmen. Theology ensures Christians will have nothing to say about nearly everything." "Theology is a "Victorian" enterprise, neoclassically bright and neat and clean, nothing out of place. Whereas the Bible talks about hair, blood, sweat, entrails, menstruation and genital emissions." "Here's an experiment you can do at any theological library. You even have my permission to try this at home. Step 1: Check the indexes of any theologian you choose for any of the words mentioned [in the previous sentence]. (Augustine does not count. Augustine's theology is as big as reality, or bigger). Step 2: Check the Bible concordance for the same words. Step 3: Ponder these questions: Do theologians talk about the world the same way the Bible does? Do theologians talk about the same world the Bible does?" There are many more useful comments, to many for this review.
Against Sacraments: "Reformed Protestants generally adopt only one physical posture in worship - sitting to listen to a sermon - and therefore we are trained in only on spiritual posture. We are trained to accept as a matter of course that it is possible to think our way through life, all of life."
This is a fragmented review, because this short book has too much in it. But the book was really excellent: highly recommended. Even where Leithart may be wrong, he'll make you think seriously about who the Church really is, and what she's called to do, and how she's called to do it.
