I was rereading the Supreme Court’s opinion in Salazar v. Buono, the case concerning a cross erected in the Mojave Desert in 1934 by a group of veterans in order to commemorate American soldiers who died in World War I. In his dissenting opinion, Justice Stevens took his usual rigid view in any case dealing with display of symbols: the cross “necessarily” conveys an “inescapably sectarian message….Making a plain, unadorned cross a war memorial does not make the cross secular. It makes the war memorial sectarian.” Justice Stevens also cited approvingly the district court judge’s view that the cross is “exclusively a Christian symbol.”

The more I read these lines, the more implausible I find them and the view of symbols that they represent. Perhaps another way to put my skepticism is that any observer who believed this about a symbol like the cross would be unreasonable–the sort of person who could not effectively administer a “reasonable observer” standard in Establishment Clause cases of this kind. The implausibility of the view is conceptual but it also is empirical. Though I recognize that anecdotes are not data, still, personal experience is worth something. The “holiday” of Halloween was for children when I was a child, but it seems to have become a kind of modern-day equivalent of Venetian Carnevale circa 1760. No matter; this year, I am grateful to Halloween for offering a useful challenge to claims about what the symbol of the cross must mean, in all times and places, for all people.

My neighborhood is child-saturated, and as a result Halloween is widely and noisily celebrated. Part of the celebration involves the display of putatively spooky lawn decorations of motley sorts, among the most popular of which is the “creepy gravesite” ensemble. It used to be that round headstones were the convention. But now one increasingly sees in such arrangements the presence of a cross. Here’s a fairly typical setup:

Probably my surreptitiously taken picture does not do justice to the mise en scène. But what it displays is a simple black Latin cross with the words RIP at the base. You can see that the cross is surrounded by other Halloween acoutrements–a skeleton in the ground, gravestones, spiderwebs. All around these sit related objects–werewolves and other hairy and unsavory creatures, a plastic witch, ghosts dangling from trees with flashing red eyes, and so on. This sort of decorative landscape is extremely common. The presence of a cross in it is less so, but just in my own neighborhood, I counted 4 displays that contained a cross of some sort.

Suppose that a municipality chose to display something like this on town hall grounds at Halloween. What would it be communicating? What does a cross mean in a display like this? Its meaning is complicated because it is situated in several contexts. It sits first within a mock cemetery but the point of the display is not remotely either commemorative (as in a memorial for the dead) or Christian. The point of the display is to celebrate, in a lighthearted, cute, and possibly mischievous way, all that Halloween has come to represent as an occasion for kids: the occult, mild wickedness, spookiness, and so on. It would make a dour schoolmarm of Christianity to say that displays like this are anti-Christian. Of course they are not. But it would verge on sheer absurdity to claim that a cross in this sort of context conveyed “an inescapably sectarian message,” or that what would otherwise be a tribute to spooky kid fun just must be transformed into a celebration of Christ by the inclusion of a cross.

It is true that even in this context, the meaning of the cross is to some extent connected to the original Christian meaning. It is so connected in this weak way: had there been no prior Christian meaning, there could have been no subsequent tradition in which crosses have come to convey a commemorative message, and therefore no cultural context within which a cross could come to find its way into a Halloween cemetery display. But noting that atavic genealogical connection is very different than assigning this particular cross–or others like it–an indelibly Christian meaning today.

It might be argued that the meaning associated with the Halloween cross only arose because people are ignorant of the Christian, soteriological meaning. That seems uncharitable to me, but also mistaken. What is more probable is that meanings intertwine, and that it becomes difficult over time to disaggregate the religious meaning from other fair, culturally specific interpretations. As I write in The Tragedy of Religious Freedom about the Mojave Desert Cross:
