Abstract Cultures define themselves largely by how they remember the past; the commemoration of history provides a link to bygone eras that helps determine social dynamics in the present. But not everyone remembers the past in the same manner. Not only do people champion competing historical narratives, but they also memorialize the past in different ways, such as erecting monuments, glorifying a specific person, constructing and honoring an archive, revering a symbol, holding an event that repeats periodically, maintaining an institution, and more. These various hubs of memory creation and preservation are often called “sites of memory.” This article explores how various Christian groups in the second century invested their social memory in divergent sites. These sites not only propagated differing forms of Christian expression, but also diverse notions of what it means to remember. While some championed preservation of the past, others believed that memory entailed radical innovation.
