Our Patron Saint
Pius is believed to have been born at Aquileia, in Northern Italy, during the late 1st century. His father was an Italian called "Rufinus", who was also said to be of Aquileia according to the Liber Pontificalis.
According to the 2nd century Muratorian Canon and the Liberian Catalogue, that he was the brother of Hermas, author of the text known as The Shepherd of Hermas.
The writer of the later text identifies himself as a former slave. This has led to speculation that both Hermas and Pius were freedmen.
Saint Pius I
Pius I's feast day is July 11. In the Tridentine Calendar it was given the rank of "Simple" and celebrated as the feast of a martyr. The rank of the feast was reduced to a Commemoration in the 1955 General Roman Calendar of Pope Pius XII and the General Roman Calendar of 1960. Though no longer mentioned in the General Roman Calendar, Saint Pius I may now, according to the rules in the present-day Roman Missal, be celebrated everywhere on his feast day as a Memorial, unless in some locality an obligatory celebration is assigned to that Feast Day.
