When I was a kid, my friends and I would occasionally hear adults talk about the pagan origins of Christmas trees. In our Christian homes, churches, and schools, such talk was not merely chat. It was actionable language. Within those overheard snippets was an implicit threat: possibly an end to the Christmas tree at home, and by extension, possibly an end to all those great things kids love about Christmas.
The anti-Christmas tree mentality never took root in my home or many other homes (although if memory serves, there were rumors some classmates’ parents had forbidden having a tree).
And I think I know why, at least in a broader sense: holiness movements and purity movements and other moralistic movements seem concerned with things the members should not-be and things they should not-do. Rarely is there a concrete, image-based sense of what is being substituted for the not-ness. (By image, here I mean anything that appeals to the perceptions of the five senses.)
The calling in those holiness, purity, and otherwise moralistic movements seems to be to achieve something more or less invisible and essentially unmodeled. Even the word “holiness,” an abstract concept, is hard to experience. But as the saying goes, nature abhors a vacuum.
So people remain under control of the images and symbols to which they attach (on varying levels, within community as much as within an individual) significance and meaning.
In most areas of life, abstract ideas cannot drive culture out of a community.
Culture is embodied in things and in relationships.
Indeed, a family Christmas tree, with its handed-down ornaments, can be both an embodiment of the holiday and a symbol for the way a particular family joins together at the same time, year after year.
To change the culture, create new, concrete images with subversive intent, and find ways to embody whatever you might be teaching or communicating.
