" Here it isn't a matter of knowing what the other knows, for Abraham doesn't know anything. It isn't a matter of sharing his faith, for the latter must remain an initiative of absolute singularity. And moreover, we don't think or speak of Abraham from the point of view of a faith that is sure of itself, any more than did Kierkegaard...Our faith is not assured because a faith never can be, it must never be a certainty. We share with Abraham what cannot be shared, a secret we know nothing about, neither him nor us. To share a secret is not to know or to reveal the secret, it is to share we know not what: nothing that can be known, nothing that can be determined. "

― Jacques Derrida , The Gift of Death
