To have faith means to dare, to think the unthinkable, yet to act within the limits of the realistically possible; it is the paradoxical hope to expect the Messiah every day, yet not to lose heart when he has not come at the appointed hour. This hope is not passive and it is not patient; on the contrary, it is impatient an active, looking for every possibility of action within the realm of real possibilities. Least of all it is passive as far as the growth and liberation of one’s own person are concerned….
The situation of mankind is too serious to permit us to listen to the demagogues – least of all demagogues who are attracted to destruction – or even to the leaders who use only their brains and whose hearts have hardened. Critical and radical thought will only bear fruit when it is blended with the most precious quality man is endowed with – the love of life
