"The lack of material goods, Saint Bernard said, is not in itself a 
virtue; rather this virtue entails loving poverty, which is also shown 
by these gestures of renunciation. This disposition is strengthened when
 one knows how to do without superfluous goods, and one is detached from
 what one has. Certainly, as Saint Josemaria said, poverty is one of our
 treasures in this world, and he pointed to the example of parents of a 
large family who, in lovingly striving to support their family, joyfully
 renounce so many personal items. Poverty is thus seen as a virtue 
needed to love (as Jesus taught us), and as part of charity. At the same
 time, we have to do everything possible to alleviate the suffering 
caused by personal and social injustices, and I see it as only natural 
that sometimes we become impatient on confronting so many injustices we 
would like to resolve."
