The New York Times reviews Olivier Roy’s Holy Ignorance, now out in English translation:

Every winter Fox News, seeking to stir up anger through the land, uncovers evidence of a war on Christmas. Secular humanists ignorant of religion and hostile to its traditions, someone in the studio will declare, want us to say “Happy Holiday” or give Kwanzaa equal standing. But Christmas, as its name suggests, is about Christ. These enemies of Christianity will stop at nothing to get their way. Not even Santa Claus is sacred to them.

Actually, as the brilliant French social scientist Olivier Roy points out in “Holy Ignorance,” it is those defending Christmas who are not being true to their traditions and teachings. There are no Christmas dinners in the Bible, which is why America’s Puritans, strict adherents of what that venerated text offers, never sat down by the raging fire awaiting St. Nick; indeed, they briefly banned Christmas in Massachusetts.

Yule as we celebrate it today owes more to Charles Dickens than to Thomas Aquinas. Our major solstice holiday is what Roy calls a “cultural construct” rather than a sectarian ceremony, which explains why Muslims buy halal turkeys and Jews transformed Hanukkah into a gift-giving occasion. Mistakenly believing that Christmas is sacred, those who defend it find themselves propping up the profane. The Christ they want in Christmas is a product not of Nazareth but of Madison Avenue.

Over the past few years, a number of theories have been offered about the rise of fundamentalism. Roy proposes the most original — and the most persuasive. Fundamentalism, in his view, is a symptom of, rather than a reaction against, the increasing secularization of society. Whether it takes the form of the Christian right in the United States or Salafist purity in the Muslim world, fundamentalism is not about restoring a more authentic and deeply spiritual religious experience. It is instead a manifestation of holy ignorance, Roy’s biting term meant to characterize the worldview of those who, having lost both their theology and their roots, subscribe to ideas as incoherent as they are ultimately futile. The most important thing to know about those urging the restoration of a lost religious authenticity is that they are sustained by the very forces they denounce.
