The Pagan stories are all about someone dying and rising, either every year, or else nobody knows where and nobody knows when. The Christian story is about a historical personage, whose execution can be dated pretty accurately, under a named Roman magistrate, and with whom the society that He founded is in a continuous relation down to the present day. It is not the difference between falsehood and truth. It is the difference between a real event on the one hand and dim dreams or premonitions of that same event on the other.
