The light of faith is unique, since it is capable of illuminating every aspect of human existence.
. . .
As a response to a word which preceded it, Abraham’s faith would always be an act of remembrance. Yet this remembrance is not fixed on past events but, as the memory of a promise, it becomes capable of opening up the future, shedding light on the path to be taken. We see how faith, as remembrance of the future, memoria futuri, is thus closely bound up with hope.
