On Tuesday morning many of us awoke to news of the brutal murder of Father Jacques Hamel in an attack on his church near Rouen, at some point during the celebration of Holy Mass. Just after reading those first reports, I was myself vesting for the morning Mass, very conscious of the similarities between his situation that morning and my own: Père Hamel no doubt began his day with no expectation of the horror that would befall him. Of course, our first response to this atrocity must be to ask the Lord to look with mercy on his servant and to grant him “the abode of refreshing, of light, and of peace,” for which we pray in the Canon of the Mass. But even as we do so, we can already benefit from the witness of Père Hamel’s life and, indeed, his death. As the Greek Orthodox theologian Christos Yannaras has said, “Martyrdom is the supreme canon of the Church’s life . . . The martyrs of the Church embody the truth of the Church, the truth of the true life which is communion and relationship with God.” Thus, even though his death has not been declared as martyrdom, nevertheless his example—like so many others—is worthy of our contemplation.
