Easter is a perfect event to demonstrate both points.
Since it belongs to the realm of the miraculous historians are not apt to accept its historicity. Theologians might because they deal with the area of faith. Many, many years ago I did not believe in the resurrection. Two arguments are usually given to discount the resurrection of Jesus and these arguments can be found within Christianity. As an aside, what people outside of Christianity believe and what they don t believe about Christianity is really of no concern to me.
