The Mortara case (Italian: caso Mortara) was an Italian cause célèbre that captured the attention of much of Europe and North America in the 1850s and 1860s. It concerned the Papal States’ seizure from a Jewish family in Bologna of one of their children, six-year-old Edgardo Mortara, on the basis of a former servant’s testimony that she had administered emergency baptism to the boy when he fell sick as an infant. Mortara grew up as a Catholic under the protection of Pope Pius IX—who refused his parents’ desperate pleas for his return—and eventually became a priest. The domestic and international outrage against the pontifical state’s actions may have contributed to its downfall amid the unification of Italy.
In late 1857, Bologna’s inquisitor Father Pier Feletti heard that Anna Morisi, who had worked in the Mortara house for six years, had secretly baptised Edgardo when she had thought he was about to die as a baby. The Supreme Sacred Congregation of the Roman and Universal Inquisition held that this made the child irrevocably a Catholic and, because the Papal States forbade the raising of Christians by members of other faiths, ordered that he be taken from his family and brought up by the Church. Police came to the Mortara home late on 23 June 1858 and removed Edgardo the following evening.
In the Mortara case, Pope Pius IX was wrong, in my opinion -— but it’s a little more complicated than it seems.
In any case, one is not canonized for being faultless. He was devoted to God -— as were, I am sure, the Mortara family. All united in Heaven I hope!
