Saint Pius X
Saint Pius X is the first canonized pope of the modern era (since Pope Saint Pius V in 1672) and the principal Catholic reformer of the early twentieth century. Pope from 1903 to 1914, he is best known for lowering the age of First Communion to the age of reason (around seven), encouraging frequent Communion, restoring Gregorian chant, codifying canon law, and resisting the theological movement called modernism. His motto, Instaurare Omnia in Christo ("To Restore All Things in Christ," Ephesians 1:10), summarized the program of his papacy.
Early life as Giuseppe Sarto
Giuseppe Melchiorre Sarto was born on June 2, 1835, at Riese, a small town in the Veneto region of northern Italy. He was the second of ten children of Giovanni Battista Sarto, the village postman and a tenant farmer, and Margherita Sanson, a seamstress. The family was poor; Giuseppe walked three and a half miles each way to school at the nearby town of Castelfranco Veneto.
He entered the seminary at Padua in 1850 at age fifteen, with a scholarship secured by the patronage of his parish priest. He was ordained priest on September 18, 1858, at twenty-three.
For the first nine years of his priesthood, Father Sarto served as a parish curate at Tombolo and then as parish priest at Salzano. He was known for his pastoral devotion to the poor, his catechetical zeal among the children of the village, and his personal asceticism (he gave away most of his salary).
Episcopal career
Father Sarto's evident pastoral gifts brought him steady promotion through the Italian Catholic hierarchy. He was named:
- Spiritual Director of the Treviso seminary (1875)
- Bishop of Mantua (1884), an impoverished and demoralized diocese which he restored to discipline and devotion through nine years of pastoral work
- Cardinal and Patriarch of Venice (1893), one of the four great patriarchal sees of the Catholic world after Rome
As Patriarch of Venice, Sarto was widely loved for his approachability, his pastoral simplicity, and his refusal to take on the aristocratic trappings of his office. He often walked through Venice's narrow streets to visit parishes on foot, dressed in his ordinary black cassock.
Election to the papacy
Pope Leo XIII died on July 20, 1903, after a twenty-five-year pontificate. The conclave that began on July 31 was marked by significant political tension. The Catholic powers of Europe (Austria-Hungary, France, Spain) traditionally claimed the right of jus exclusivae, a veto on candidates considered hostile to their interests. The Austrian emperor Franz Joseph attempted to use this veto against the leading candidate, Cardinal Mariano Rampolla, the late pope's secretary of state.
After several rounds of voting, the cardinals turned to Sarto as a compromise. He resisted strenuously; he reportedly wept and begged not to be elected. On August 4, 1903, on the seventh ballot, he was elected. He took the name Pius X.
His first official act as pope was to abolish the right of jus exclusivae. No state would again exercise a veto in a papal conclave.
Reforms of the papacy
Pope Saint Pius X's eleven-year pontificate produced reforms across nearly every area of Catholic life:
- Eucharistic reform: The decrees Sacra Tridentina Synodus (1905) on frequent Communion and Quam Singulari (1910) on early Communion lowered the age of First Communion from approximately twelve or older (the common practice of the nineteenth century) to the age of reason (around seven). Frequent and even daily reception of the Eucharist was encouraged. The Catholic devotional life of the twentieth century was fundamentally shaped by these decrees.
- Liturgical music: The motu proprio Tra le Sollecitudini (1903) restored Gregorian chant as the proper music of the Roman liturgy, displacing the operatic settings that had dominated nineteenth-century Catholic church music.
- Canon law codification: Pius X initiated the project of codifying Catholic canon law (the disorganized accumulation of centuries of decrees) into a single coherent code. The Code of Canon Law was published by his successor Pope Benedict XV in 1917.
- Seminary reform: regulations for seminary education across the universal Catholic Church.
- Anti-modernism: the encyclical Pascendi Dominici Gregis (1907) and the syllabus Lamentabili condemned the theological movement called modernism (broadly: the application of higher-criticism and historicist methods to revelation, doctrine, and biblical interpretation, in a way that the Catholic Church then judged corrosive of doctrinal stability). The Anti-Modernist Oath, required of all Catholic clergy and seminary professors from 1910 to 1967, dates from this period.1
The First World War and death
In June 1914, the assassination of Archduke Franz Ferdinand of Austria at Sarajevo set off the chain of events that would lead to the First World War. Pius X spent the summer of 1914 in desperate diplomatic efforts to prevent the outbreak. He failed. Austria-Hungary declared war on Serbia on July 28. By August 4, when the war had spread to Russia, France, Germany, and Britain, the pope was reportedly devastated.
Pius X died at the Vatican on August 20, 1914, just over three weeks after the outbreak of the war. The traditional account holds that he was "broken-hearted" by the war. Whatever the precise cause, his death at age seventy-nine was attributed by witnesses to the strain of the diplomatic crisis.
Canonization and patronage
Pius X was beatified by Pope Pius XII on June 3, 1951, and canonized by the same pope on May 29, 1954. He was the first pope canonized since Pope Saint Pius V in 1672.
Saint Pius X is patron of first Communicants (from his decree Quam Singulari), of catechists, of the Patriarchate of Venice, and of pilgrims. His feast was originally celebrated on September 3 (the date of his coronation as pope), but was moved to August 21 in the 1969 calendar reform, near the date of his death. It is celebrated as a Memorial in the universal Catholic Church.
