The world has shrunk in the processes of globalization, and the old ways of actively ignoring plurality in theology are no longer viable. Contextual differences between different Christian traditions and theologies are highly visible due to improved communications and migration. These differences also witness that this plurality has existed since the very beginning of Christianity. Religious studies demonstrate that no religion is pure and hermetically sealed from others, but they all are syncretistic in the sense of giving and taking. In the world of religions, where boundaries are porous and the internal plurality of Christianity is vast, there is a temptation either to reject the plurality in a fideistic manner or succumb to relativism. The first solution is intellectually hard to defend, and relativism is often seen as detrimental to Christian identity. This book proposes a way of recognizing the contextual and syncretistic dimensions of pluralism while not surrendering to relativism. Christian identity and tradition can be affirmed while staying open to the challenges of pluralism.
