The only Christians who still talk about the apocalypse are fundamentalists, but they have a completely mythological conception of it. They think that the violence of the end of time will come from God himself. They cannot do without a cruel God. Strangely, they do not see that the violence we ourselves are in the process of amassing and that is looming over our own heads is entirely sufficient to trigger the worst. They have no sense of humor.
(From Battling to the End by (2010; Achever Clausewitz, 2007) by Rene Girard, in which he turns the focus of his mimetic insights from the history of human culture and religion to the future of humankind and the crucial importance of Christianity’s apocalyptic vision. You can find Girard’s own summary of it at First Things.)
