One might not consider history a theological concept, but when a substantial group's theological belief is that the only purpose of their religion is to convince people to adopt beliefs in order to go to an afterlife destination, than history becomes irrelevant and it becomes excusable to not teach or remember history. And then the lessons of history are forgotten and horrendous acts are repeated. History becomes a deeply theological issue when considering not only that God is present in history, but present in liberating ways.
