Saint Joseph Calasanz
Saint Joseph Calasanz, founder of the first Christian public school and of the Order of the Piarist Fathers, was born in Peralta de la Sal in 1557. God wanted Calasanz to be a mediator, so that he could enrich the Church with a new charismatic gift.
God gave Calasanz some natural gifts and a family context which allowed him to have a long and positive Christian and cultural education. God called him to be a priest, a ministry that he practised in various curial and pastoral missions. Nine years after his ordination as a priest, he went to Rome, where he was struck by the misery of the youth in the poorest suburb of the city.
This is the context where his vocation was originated. He heard the voice of God calling him: "Joseph, give yourself for the poor. Teach these children and take care of them".
