"Jenny Leith’s account of Christian formation is insightful, original, and timely. She shows that formation happens both in the church and in the wider world, and that we shouldn’t accept any monochrome picture of where good formation takes place. And she out a rich and exciting vision of humble but determined Christian participation in practical politics, and of the transformations that such participation can bring in its wake. This is an important book, and an urgent one, for anyone interested in the church’s place in the contemporary world."
