"This, today, was something else altogether. The target of this revenge was not the West in general, nor its complacent and egotistical prosperity, which can seem insulting to the penniless inhabitants of the world beyond. The target of this revenge was the root of the West, the West’s living source, even when it is unremembered—namely Christianity, in the time and the place where, tacitly but invincibly, it becomes most explicitly and intensely real: the celebration of the Mass."
It is only a short article so it is excused for not mentioning what others have mentioned about this killing of a priest, that now on the shores of Europe the fate of many Christian priests and laity in the Levant as well as Copts in Egypt is being experienced. Martyrdom is in the West's own neighbourhood.
My title here is the opposite to Jean Duchesne's because I think there is a "both/and" here. We are "Je Suis Jacques Hamel" as we identify with Jacques as our brother in the suffering Christ, along with all present day Christian martyrs. We are also, because we are alive, our throats have not been cut, "Je Ne Suis Pas Jacques Hamel." What is God calling us to do and be as those not yet martyred?
