Historicism is a way of thinking about history and how it relates to Christianity. In Christianity, historicism looks at how the Bible and its teachings have played out in the world and how they have changed over time. It looks at how events and people in the past have shaped Christian theology and how the theology has changed over time. In other words, it looks at history as a series of events that have all contributed to the development of the Christian faith. Historicism can help Christians understand where they have come from and where they are going.
