'Theological students for many years to come will find this book indispensable. It summarises the teaching of theologians on the key subject of the Kingdom of God during this century, with a brief backward look at Schleiermacher and Ritschl. Concisely and fairly Dr Perrin traces the development, from Johannes Weiss and Schweitzer and the unsuccessful reaction against them, on to Dodd, Manson and Bultmann. He well illustrates the inexorable dialectic of theological thought, and the impossiblity of a mere return to older positions, however much one may react against current expositions. It is a fascinating story, enlivened by occasional tart observations.' (Church Times) 'Dr Perrin's book gives the impression that real progress has been made in the century of scholarship it surveys, and ends with a discussion of the questions which remain outstanding for future research, including some radical questions about the meaning and intention of biblical eschatology and its relation to the course of history and to the purposes of God.' (Expository Times) 'As well as being a valuable treatment of the subject in its own right, this volume is an important contribution to the continuing debate about christology. which has an obvious relation to the kingdom theology of the gospels.' (The Churchman)
