Pier Giorgio Frassati (6 April 1901 – 4 July 1925) was an Italian Catholic activist and a member of the Third Order of Saint Dominic.

[2] He was dedicated to Catholic social justice issues and joined several charitable organizations, including Catholic Action and the Society of Saint Vincent de Paul,[3] to better aid the poor and less fortunate living in his hometown of Turin; he put his own pious beliefs into practice to cater to their needs and was best known for his devotion and amiable character.

Pope Pius XII suspended the cause in 1941 due to a range of allegations later proven to be false, which allowed for the cause to resume.

The sobbing Frassati told his mother of this and she instructed him to find the man and bring him to the home for something to eat.

Frassati was dedicated to works of social action that would unite people together in fellowship as a means of combating inequalities.

[9] He was involved with student groups as well as the Apostolato di preghiera and Catholic Action (joined in 1919) to which he dedicated himself.

[4] He helped establish a newspaper entitled Momento whose principles were based on Pope Leo XIII's Rerum novarum.

He joined the Saint Vincent de Paul group in 1918 and spent much of his time helping the poor and less fortunate.

He also provided a bed for a tuberculosis sufferer on one occasion as well as supporting the three children of an ill widow and finding a place for an evicted woman.

[6] His talents seemed to be limitless for he was an avid mountaineer and athlete who could swim well and could even recite Dante passages with relative ease.

Frassati was a member of the Club Alpino Italiano and climbed mountains such as the Grand Tournalin and Monte Viso.

On 30 June 1925, while boating with two friends on the Po River, he began to complain of sharp pains in his back muscles.

All were surprised to find the streets lined with thousands of mourners as the cortege passed out of the reverence felt for him among the people he had helped.

Frassati's writings were also collected for examination to ensure no doctrinal breaches were present since that would impede the cause to a significant degree; theologians cleared them on 21 December 1938.

The Congregation for the Causes of Saints issued a decree of validation on 12 June 1987 for the previous processes and received the Positio dossier from the postulation later in 1987.

John Paul II granted final approval to the miracle on 21 December 1989 which also confirmed that Frassati would soon be beatified.

[12] Pier Giorgio Frassati is the patron of Bishop McGuinness High School in Oklahoma, and the school awards the "Blessed Pier Giorgio Frassati Award" to its students who have performed a high level of service to others.

In 1989 John Paul II visited his tomb and paid honor to him calling him the "Man of the Eight Beatitudes".

Frassati's remains have been moved from their resting place in Turin twice, for two occasions of World Youth Day, with one being in Sydney in 2008, and the other in Kraków in 2016.

On 27 April 2024, Cardinal Marcello Semeraro, prefect of the Dicastery for the Causes of Saints, announced during the 18th National Assembly of Italian Catholic Action that the canonization of Frassati had been cleared.
