04 November - Charles Borromeo, born in Arona on 2 October 1538. At the age of 12, he received the tonsure and benefit of the Benedictine Abbey of Arona, left vacant by his uncle Giovanni Angelo de Medici, who was Pope Pius IV.

In 1561 the same uncle intervened to promote Charles to the position of Cardinal Secretary of State. Appointed Archbishop of Milan in 1564, he resigned from all his other offices in Rome in order to reside permanently in his diocese. His personal integrity, his understanding of situations and his radiant virtue facilitated the restoration of ecclesiastical discipline. He endeavoured to implement the measures taken at the Council. First of all, he took up residence in Milan and opened a seminary to improve the training of the clergy. He restored the observance of the rule in the convents and had the parlours fitted with gratings.

One of the orders he wanted to reform, the Order of the Humiliated, tried to have him assassinated, but he escaped the assassin's blows. During the plague that devastated Milan in 1576, he brought help and consolation everywhere, ignoring the dangers of contagion. In 1581, he founded a congregation of Oblates, secular priests who would later become known as the "Oblates of Saint Charles". He died in 1584, at the age of 46, exhausted by fatigue and austerities.

His tomb was the scene of healings that were considered miraculous, which enabled the start of his beatification process, which culminated in 1609 before Pope Paul V. He was canonised on 1 November 1610 by Paul V. He is one of the very few saints whose canonisation process was completed only one year after his beatification.
