Feast Day: June 27
Saint Arialdus of Milan, also known as Arialdo, was a courageous and well-educated deacon in the archdiocese of Milan, Italy. He was born in the 11th century and dedicated his life to serving the Church. Arialdus was highly respected for his knowledge and piety, and he was appointed as a teacher at the prestigious cathedral school of Milan. It was during his time at the school that he became deeply involved in the religious and political conflict known as the Pataria. The Pataria was a movement that aimed to combat the widespread corruption in the Church, particularly the practices of simony (the buying and selling of ecclesiastical offices) and nicolaism (clerical marriage and concubinage). Guided by their leaders, the Patarini, they sought to bring about spiritual renewal and reform within the Church. Arialdus played a crucial role in leading the anti-nicolaism and anti-simony efforts in Milan, starting in 1057. He was supported by the Vatican in his mission but faced opposition from his archbishop, Guido da Velate, who was involved in simoniac practices. The dispute between Arialdus and Guido da Velate quickly escalated and resulted in violent confrontations. Fearing for his life, Arialdus went into hiding outside the city, continuing his work from a secret location. Pope Alexander II, recognizing the righteousness of Arialdus' cause, excommunicated Archbishop Guido. However, Guido did not relent, and he retaliated by having Arialdus hunted down and arrested. Arialdus was imprisoned and ultimately executed for his steadfast commitment to reform and his refusal to back down from his principles. He died a martyr's death in 1066 at a castle on a small island in Lago Maggiore near Milan. After his execution, Arialdus' body was re-interred in a monastery in Milan in 1067. Pope Alexander II declared him a saint in the same year, recognizing his martyrdom and devotion to the Church. The cult of Saint Arialdus grew over the centuries, prompting Pope Pius X to confirm his cultus in 1904. As a saint, Arialdus is a symbol of unwavering faith, dedication to Church reform, and the fight against corruption. Although he faced great opposition and suffered martyrdom, his commitment to upholding the righteousness of the Church remains an inspiration to believers throughout the ages. Saint Arialdus' feast day is celebrated on June 27th, acknowledging his significant contributions to the Catholic faith and his ultimate sacrifice for the sake of spiritual renewal.
