High Quality Content by WIKIPEDIA articles! Pope Saint Pius X (Ecclesiastical Latin: Pius PP. X) (2 June 1835 – 20 August 1914), born Giuseppe Melchiorre Sarto, was the 257th Pope of the Catholic Church, serving from 1903 to 1914. He was the first pope since Pope Pius V to be canonized. Pius X rejected modernist interpretations of Catholic doctrine, promoting traditional devotional practices and orthodox theology. His most important reform was to publish the first Code of Canon Law, which collected the laws of the Church into one volume for the first time. He was a pastoral pope, encouraging personal piety and a lifestyle reflecting Christian values. He was born in the town of Riese, which would later append "Pio X" (Pius X`s name in Italian) to the town`s name.
