By establishing schools for the poor, Calasanz tried to instigate
social revolution, in solidarity with the defenders of the oppressed and against those who defended the status quo. He expressed
this social preoccupation strongly and frequently. Of course, he used the terms of his time,
"The reformation of Christian society consists
in the diligent exercise of the teaching profession. The good education of youth is the most effective remedy for preserving
and curing youth from evil. It is, at the same time, the induction and illumination of good. From it depends the peace and
tranquility of people, good government, the propagation of the faith, conversion, and preservation from heresies, and, lastly,
the reform of Christian society, because it teaches people to live well."
