We live in an age beset by religiously inspired violence. Terms such as “holy war” are the stock-in-trade of the evening news. But what is the relationship between holiness and violence? Can acts such as murder ever truly be described as holy? This book offers a searching philosophical investigation of holiness and ethics in the Jewish tradition, and more specifically whether Judaism condones violence. Jewish texts feature episodes of divinely inspired violence, and the position of the Jews as God's chosen people has been invoked to justify violent acts today. Are these justifications valid? Or does our understanding of the holy entail an ethic that argues against violence? Reconstructing the concept of the holy through a philosophical examination of biblical texts, the book finds that holiness and goodness are inextricably linked, and that our experience of holiness is authenticated through its moral consequences. Our understanding of the holy develops through reflection on God's creation of the natural world, and our values emerge through our relations with that world. Ultimately, the book concludes, religious justifications for violence cannot be sustained. This book is a powerful counterargument to those who claim that the holy is irrational and amoral. With philosophical implications that extend far beyond the Jewish tradition, this book should be read by anyone concerned about the troubling connection between holiness and violence.
