Christoph Markschies, now professor at Heidelberg, is the scholar of the rising generation who looks most likely to become one of the internationally known figures in the scholarship of early Christianity. His Between Two Worlds, published by SCM Press, is a fascinating introduction to the social practices of early Christians. He combines great clarity of writing with immense learning. In 128 pages there is everything the reader needs to know, along with where to look for further information. If ever a book was worth translating this is: it would be ideal for schools, university and theological students and clergy in length, approach and everything else. John Bowden
