About Arialdo

Saint Arialdo

Saint Arialdo (c. 1010 – June 27, 1066) was an eleventh-century Christian reformer and martyr, primarily associated with the city of Milan. He is chiefly remembered for his pivotal role in the pataria movement, which sought to cleanse the Milanese clergy of simony and immoral practices.

Life and historical context

Born into a noble family at Cutiacum (modern Cucciago) near Como, Arialdo received his education in Laon and Paris before becoming a canon in the cathedral city of Milan. At this time, the church in Milan was reportedly plagued by clerical misconduct, including fornicating, engaging with prostitutes, and the sale of indulgences. The practice of marriage was also common among the Milanese clergy, according to historical accounts.

Arialdo, alongside Bishop Anselmo da Baggio of Lucca (later Pope Alexander II), became a leader of the pataria movement. This movement aimed to reform the clergy, particularly targeting those involved in simony. Due to his reformist zeal, Arialdo was excommunicated by the Bishop of Milan, Guido da Velate. However, Pope Stephen IX later removed this excommunication, allowing Arialdo to return to Milan and continue his efforts. The conflict eventually escalated, becoming not just a matter of clerical conduct but also a dispute over the authority of Rome over Milan. In an attempt to resolve the issue, Pope Stephen IX sent Peter Damiani as a legate in 1069, who demonstrated that Milan's patron saint, Ambrose, had acknowledged the papacy's precedence.

These endeavors ultimately led to Bishop Guido da Velate's excommunication. While Arialdo was traveling to Rome, he was ambushed and killed by emissaries of Bishop Guido.

Veneration and legacy

Approximately ten months after his assassination, Arialdo's body was recovered from Lago Maggiore. It was reportedly found in a state of perfect preservation and emitting a sweet odor. His remains were transported to Milan and displayed in the church of St. Ambrose from Ascension to Pentecost. Subsequently, Arialdo's body was interred in the church of St. Celsus. In the following year, 1067, Pope Alexander II officially declared him a martyr. His martyrdom became a significant event in the history of the pataria and the broader Gregorian Reform movement.
