Some critique the Jesus story by saying there are historically antecedent stories of a dying and rising god.
Re. this, here's a thought from C.S. Lewis:
“In the New Testament, the thing really happens. The Dying God really appears—as a historical Person, living in a definite place and time. . . . The old myth of the Dying God . . . comes down from the heaven of legend and imagination to the earth of history. It happens— at a particular date, in a particular place, followed by definable historical consequences. We must not be nervous about ‘parallels’ [in other religions] . . . : they ought to be there—it would be a stumbling block if they weren’t.”
