“His pedagogical idea of educating every child, his schools for the poor, his support of the heliocentric sciences of Galilei and his service towards children and youth all aroused the opposition of many among the governing classes in society and the ecclesiastical hierarchy. In 1642, as a result of an internal crisis in the congregation as well as outside intrigues and pressures, Calasanz was briefly held and interrogated by the Inquisition.
“Problems were exacerbated, however, by Father Stefano Cherubini, originally headmaster of the Piarist school in Naples, who systematically sexually abused the pupils in his care. Cherubini made no secret about some of his transgressions, and Calasanz came to know of them. Unfortunately for Calasanz as administrator of the Order, Cherubini was the son and the brother of powerful papal lawyers and no one wanted to offend the Cherubini family. Cherubini pointed out that if allegations of his abuse of his boys became public, actions would be taken to destroy the Order. Calasanz therefore promoted him, to get him away from the scene of the crime, citing only his luxurious diet and failure to attend prayers. However, he knew what Cherubini had really been up to, and he wrote that the sole aim of the plan was “to cover up this great shame in order that it does not come to the notice of our superiors”.
“Superiors in Rome found out but bowed to the same family ties that had bound Calasanz. Cherubini became visitor general for the Piarists. The Piarists became entangled in church politics and, partially because they were associated with Galileo, were opposed by the Jesuits, who were more orthodox in astronomy. (Galileo’s views also involved atomism, and were thought to be heretical regarding transubstantiation.) The support for Cherubini was broad enough that in 1643, he was made superior general of the Order and the elderly Calasanz was pushed aside. Upon this appointment, Calasanz publicly documented Cherubini’s long pattern of child molestation, a pattern that he had known about for years. Even this did not block Cherubini’s appointment, but other members of the Order were indignant about it, although they may have objected to Cherubini’s more overt shortcomings. With such dissension, the Holy See took the easy course of suppressing the Order. In 1646, it was deprived of its privileges by Pope Innocent X.
“Calasanz always remained faithful to the Church and died August 25, 1648, at the age of 90, admired for his holiness and courage by his students, their families, his fellow Piarists, and the people of Rome. He was buried in the Church of San Pantaleo.”

In the meantime, Pope Francis has declined the possibility that priests might marry [women]. Nothing changes. Until it does. I expect married Roman Catholic priests within a century.
