The fact that Christianity’s central claims (the death, burial, and Resurrection of Jesus) can be analyzed by the legal-historical method of proof makes it different from other religions. Unlike Christianity, many other religions cannot be proven true or false using the historical method. But if Christianity is true, because of its unique historical claims, it can be demonstrated to be true, not by the scientific method, but by the legal-historical method.
This does not mean that science or the “sciences” such as archaeology or textual criticism1 cannot be used to help confirm Christianity. In fact, scientific facts do a lot to support the validity of Christianity. I am simply saying you can’t use what is called “the scientific method” to prove Christianity. You must use the legal-historical method of proof.
