Joseph Calasanz
Spanish writer and saint
Feast: 25 August (current Roman calendar, optional memorial) · 27 August (1962 Missal, III class)
Who they were
Joseph Calasanz was born in Aragon to a family of modest nobility; his father, a blacksmith, wanted him to be a soldier but let him study at Lleida and Valencia. A priest and vicar general of the diocese of Urgell, he went to Rome in 1592, where he tutored the Colonna cardinal's nephews while visiting the sick and prisoners.
What struck him most were the children abandoned in the streets to ignorance and vice. With the help of the parish priest of Santa Dorotea in Trastevere, who lent him two rooms, he opened the first free public school in Europe for poor children, and founded the Piarists, the Clerics Regular of the Pious Schools. He died in 1648 without seeing his order restored after its suppression; it was re-established in 1699, its members adding a fourth vow to educate the young.
The miracles
In 1948 Pius XII named him universal patron of Christian popular schools. The miracles examined for his canonisation are not described in the sources we have used.
Why that counted as sanctity
Calasanz saw that teaching poor children is a noble mission, like the work of their guardian angel, and gave his life to it through ruin and suppression of his own order.
