The canonisation ceremony will be held exactly 100 years since the first apparition of Our Lady of Fatima

Pope Francis will declare the sainthood of Blessed Jacinta Marto and Blessed Francisco Marto, two of the shepherd children who saw Mary in Fatima, Portugal, during his visit to the site of the apparitions on May 13.

The date was announced during an “ordinary public consistory”, a meeting of the Pope, cardinals and promoters of Causes that formally ends the sainthood process.

Cardinal Angelo Amato, prefect of the Congregation for Saints’ Causes, addressing the assembly noted that of the future saints considered at the consistory, five were children or young teenagers.

“In our time, where young people often become objects of exploitation and commerce, these young people excel as witnesses of truth and freedom, messengers of peace [and] of a new humanity reconciled in love,” the cardinal said.

At the same consistory, the Pope set on October 15 as the date for the canonizations of two priests and two groups of martyrs, including Blessed Cristobal, Blessed Antonio and Blessed Juan – also known as the “Child Martyrs of Tlaxcala” – who were among the first native converts in Mexico. They were killed between 1527 and 1529 for refusing to renounce the faith and return to their people’s ancient traditions.

Pope Francis will preside over the canonisation ceremony of the Fatima visionaries during his visit to Fatima on May 12-13.

The pilgrimage will mark the 100th anniversary of the Marian apparitions, which began on May 13, 1917, when 9-year-old Francisco and 7-year-old Jacinta, along with their cousin Lucia dos Santos, reported seeing the Virgin Mary. The apparitions continued once a month until October 13, 1917, and later were declared worthy of belief by the Catholic Church.

A year after the apparitions, both of the Marto children became ill during an influenza epidemic that plagued Europe. Francisco died on April 4, 1919, at the age of 10, while Jacinta succumbed to her illness on February 20, 1920, at the age of 9.

Francisco and Jacinta’s Cause was stalled for decades due to a debate on whether non-martyred children have the capacity to understand heroic virtues at a young age. However, in 1979, St John Paul II allowed their Cause to proceed; he declared them venerable in 1989 and beatified them in 2000.

The children’s cousin entered the Carmelites. Sister Lucia died in 2005 at the age of 97. The diocesan phase of her Cause concluded in February and now is under study at the Vatican.

The other canonisations set to take place on October 15 include:

— The “Martyrs of Natal,” Brazil, including: Blessed Andre de Soveral, a Jesuit priest; Blessed Ambrosio Francisco Ferro, a diocesan priest; Blessed Mateus Moreira, a layman; and 27 others. They were killed in 1645 in a wave of anti-Catholic persecution carried out by Dutch Calvinists.

— Blessed Faustino Miguez, a Spanish priest and member of the Piarist Fathers born in 1831. He started an advanced school for girls at a time when such education was limited almost exclusively to boys. While he taught a variety of subjects and wrote numerous textbooks, he also honed an interest in botany, which led him to find a cure for a professor so ill that he was thought to be beyond hope. People then came to him from all parts of the country seeking relief from their sicknesses.

— Blessed Angelo da Acri, an Italian Capuchin priest who was born Luca Antonio Falcone. A famed preacher, he was known for his defence of the poor. He died in 1739 and was beatified by Pope Leo XII in 1825.
