This book was published in 1995 and although still very acute and with some useful points it does somehow feel dated. Some things, however, don't date - or at least date very slowly! - so Dave Tomlinson's discussion of the post-modern influence on evangelicalism is still valid, and particularly so for this reader.
The basic premise is that the church (and specifically in the case of this book the Evangelical wing of the church) fits into the 'Modern' society method of absolute truth, rationality, literal meaning of texts and proscriptive behaviours; unfortunately for the church the rest of the world has moved on to an imprecise, ambiguous and symbolic world as the penny has dropped that life has rather more to it than the 'modern' model offered. The argument of this book is that many Christians can no longer subscribe to the core requirements of the evangelical church (requirements, we note, that are usually not significant in the Bible) and either join the liberal church, have church once a year at Greenbelt or drift away altogether.
This is a fairly short book at 145 pages which serves to introduce the topic, to give a few examples and to map out the directions in which many post-evangelicals might move. There's not enough space to go deeply into any of the topics which was, for me, a slight failing of this book. It more serves as background for the reader to decide if this area of thought is that which will help them with their faith problems. I can recommend Brian MacLaren's "A New Kind Of Christian" as the more recent and in-depth book that would complement this very well.
There is a real benefit, however, in the simplicity of the writing style of this book. It was easy to identify myself in much of his writing and the confidence this gave - that I'm not alone in my disillusionment with modern Christianity - was very helpful. The datedness of the book is in terms of the examples he gives and perhaps also in the very discussion of 'evangelical' and 'evangelicalism' rather than just 'Christian'; I have a suspicion that the evangelical wing has grown so much in the twelve years since this book was published that it has subsumed most other areas and to me this book seemed to be saying a lot about the 'average' and 'normal' church of a medium-sized town in England, not necessarily one that would shout from the rooftops that it was evangelical. Be that as it may, this is an interesting book which gives encouragement to further reading and references some useful other works in its endnotes.
