Biblical Christianity refuses to separate historical fact from spiritual meaning. Its core claim is that the living God has acted in history, especially in the life, death, and resurrection of Jesus. Other religions tell people what they must do to achieve salvation, or become holy, or reach Nirvana, or connect with the divine. The burden of obligation is on the individual to perform the right ceremonies or perfect the right rituals. The Christian gospel is unique because it is the narrative of what God has done in history to accomplish salvation.
