The author, professor at the University of Chicago Divinity School, describes the subject of this book as that of the relation of the church to the world. His concern is not theological or philosophical, but practical. The problem for the church-- American Protestantism in particular -- is to be ""in but not of"" the world -- relevant but still transcendent. The tempations be setting the church to succumb to secular culture are discussed in their historical perspective as well as in their present manifestations. Chapters deal with the General Nature of the Problem, the Historical Background, the concept of The People of God, Hearers of the Word, and the church as the Body of Christ. A ""theological epilogue"" considers the problem raised by the church's language. The solution to the overall problem considered is found in the ministry of the church in Word and Sacrament. It would seem that this solution states, rather than answers the problem of relevance to secular culture. The book should be a helpful and readable contribution to the wide discussions now going on over the question of the church's relation to the secular world.
