Faith is very often understood by people as a defeat of intelligence. In other words, faith begins when I can no longer think creatively, when I let go of any attempt at rational understanding, and when I say ‘I believe’ because it is so absurd that it is the only way of facing the problem. This may be an act of credulity, it may be an act of cowardice, it may be a preliminary act, full of wisdom and intelligence, that teaches us not to draw conclusions or to come to conclusions before we have understood. But this is not faith as understood by the great men of all religions, and particularly the Christian faith. In the Epistle to the Hebrews in the eleventh chapter, faith is defined as ‘certainty of things unseen’. We usually lay the stress on ‘things unseen’ and forget the ‘certainty’ about them. So when we think of faith we usually think of the invisible and instead of certainty put against it an interrogation mark. Then to solve the problem, we accept in a childish way, in an unintelligent way very often, what we are told by others — usually our grandparents of three generations back, or whoever else we choose to believe for reasons that are not always reasonable. But if you try to see the way in which faith originates in those people who were the great men of faith, the heroes of faith, you can see that it always originates in an experience that makes the invisible certain, and which allows them, having discovered that the invisible is as real as the visible, to go further in searching the invisible by methods of their own.
