5 Through these considerations, the poor and those who live by the labour of their hands should be of good heart and learn to be just. If they win the right of emerging from poverty and obtaining a better rank by lawful means, reason and justice uphold them in changing the order established, in the first instance, for them by the Providence of God. But recourse to force and struggles by seditious paths to obtain such ends are madnesses which only aggravate the evil which they aim to suppress. Let the poor, then, if they would be wise, trust not to the promises of seditious men, but rather to the example and patronage of the Blessed Joseph, and to the maternal charity of the Church, which each day takes an increasing compassion on their lot.
