13 In the course of their history, Christians have tried to express this “knowing without knowing” by means of figures that can be represented, and they have developed images of “Heaven” which remain far removed from what, after all, can only be known negatively, via unknowing. All these attempts at the representation of hope have given to many people, down the centuries, the incentive to live by faith and hence also to abandon their hyparchonta , the material substance for their lives. The author of the Letter to the Hebrews , in the eleventh chapter, outlined a kind of history of those who live in hope and of their journeying, a history which stretches from the time of Abel into the author's own day. This type of hope has been subjected to an increasingly harsh critique in modern times: it is dismissed as pure individualism, a way of abandoning the world to its misery and taking refuge in a private form of eternal salvation. Henri de Lubac, in the introduction to his seminal book Catholicisme. Aspects sociaux du dogme , assembled some characteristic articulations of this viewpoint, one of which is worth quoting: “Should I have found joy? No ... only my joy, and that is something wildly different ... The joy of Jesus can be personal. It can belong to a single man and he is saved. He is at peace ... now and always, but he is alone. The isolation of this joy does not trouble him. On the contrary: he is the chosen one! In his blessedness he passes through the battlefields with a rose in his hand”.
