As a result of Islamic terrorism many people - including some in high places - have quickly come to the conclusion that Islam is a religion of violence and, as such, is the sworn enemy of Christianity and the Western way of life. This may be understandable, but the matter is not quite so simple. This book provides the necessary historical background to the problem, and it does so by supplying a wealth of documentation which powerfully records the amicable and fruitful relations which, over the centuries, have repeatedly manifested themselves between Christianity and Islam. What has gone wrong now? Is it possible that this spirit, once so frequent, can again be recovered - in whole or even in part? On the evidence presented in this book, this would seem to be more than just a pious hope. The Old Testament says: "My people are destroyed from lack of knowledge. Because thou hast rejected knowledge, I will also reject thee." This book copiously supplies the background knowledge that is needed for our understanding in this age of absurd, cruel, and apparently unending wars.
