List of saints canonized by Pope Pius XII

On 29 May 1954, less than three years after his beatification, Pius X was canonized, following recognition of two more miracles. The first involved Francesco Belsami, an attorney from Naples who had a fatal pulmonary abscess, who was cured after placing a picture of Pope Pius X upon his chest. The second miracle involved Sr. Maria Ludovica Scorcia, a nun who had a serious neurotropic virus, and who, after several novenas, was entirely cured. The Canonization mass was presided over by Pius XII at Saint Peter's Basilica before a crowd of about 800,000[7] of the faithful and church officials at St. Peter's Basilica. Pius X became the first Pope to be canonized since the 17th century.

Pope Pius XII canonized Saint Maria Goretti as a virgin and martyr saint of the Roman Catholic Church. Maria's mother, nicknamed "Mamma Assunta" by her neighbors, was present at the ceremony; she was the first mother ever to attend the canonization ceremony of her child, along with her four remaining sons and daughters. Her murderer Alessendro also was present at the canonization.[8]

Because of the huge number of visitors, the canonisation of Maria Goretti by Pope Pius XII, was held outside at Piazza San Pietro on 24 June 1950. The Pope spoke, not as before in Latin, but in Italian. "We order and declare, that the blessed Maria Goretti can be venerated as a Saint and We introduce her into the Canon of Saints". Some 500,000 people, among them a majority of youth, had come from around the World. Pope Pius asked them:

• Young people, pleasure of the eyes of Jesus, are you determined to resist any attack on your chastity with the help of grace of God?

A resounding Yes was the answer.[9]

Pope Innocent XI, personally a holy man, was highly controversial even hated, because of his opposition to the French monarchy and its aspirations for European hegemony; but also for his family's engagement in money-lending. He opposed French attempts to usurp the traditional liberties of the Church, for example in nominating its bishops. He opposed Gallicanism, the Gallican Liberties demanded by the French king. The case for his canonization was introduced in 1714 but the strong emotional and political influence of France forced a postponement until Pope Pius XII, who reintroduced the case, announced his beatification on 7 October 1956.

The Placet Eugenio was the required final approval by the Pope of proposed candidates. Not all, who had passed the Vatican tribunals, received the Placet Eugenio. In one instance, Pius found, that the candidate, supposedly a model of virtue, had consistently used foul language.[10] Refusing to accept the Vatican defense, that this kind of language was custom in that region, he stopped the proceedings shortly before their conclusion. Another person, belonging to a large religious order, was refused the honour of the altars, because he turned out to be a chain smoker. "Monsignore, as long as I am alive, this Causa will not find approval". This case too was almost completed and the relatives and members of the order were quite disappointed.[10]

According to Halecki and Murray, Pius has shown a particular interest in the discovery and recognition of sanctity among American religious leaders and pioneers of the Church movement. The first "American" saint was canonized during his pontificate, when Mother Cabrini, an Italian born nun with American citizenship, was raised to sainthood in St. Peter's Basilica.[11] Pius also accelerated the canonization of other Americans, including American born Mother Seton of Emmitsburg, Maryland, founder of the Sisters of Charity. Fourteen months after his death, she was declared Venerable and was later beatified by Pope John XXIII and canonized by Pope Paul VI. Pope Pius supported also the case of an American Indian woman from the Mohawk tribe, Saint Kateri Tekakwitha, who was declared "Venerable" by him in 1943.[12]
