Little attention has been paid to the Christian churches in memory studies in southern Africa. Using new and existing research, the paper proposes a first approach to this new field of enquiry, with special reference to southern African Christianity. The churches embody their memories in liturgies, canonisations, monuments, commemorative events and name-giving practices. They utilise what French historian Pierre Nora calls lieux de mémoire (sites of memory). Commemorations reinforce identity, especially when identities are threatened by external forces, and they create social cohesion. By pointing at the past, they create meaning for the present. Churches, ecumenical bodies, religious movements and theological institutions articulate their memories in various ways. Memories can be lost and retrieved, contested or marginalised. When the context changes, in church as in society, memories which were oppositional at one point can become dominant or vice versa.
