It is necessary not only to relieve the gravest needs but to go to their roots, proposing measures that will give social, political and economic structures a more equitable and solidaristic configuration.

We, however, have a different goal: the Son of God, the true man. He is the measure of true humanism. An "adult" faith is not a faith that follows the trends of fashion and the latest novelty; a mature, adult faith is deeply rooted in friendship with Christ.
