Antonio Ghislieri was born in Bosco Marengo in northwest Italy. As a child, he worked to help support his family. At age fourteen, he joined the Dominicans, taking the name Michele, and received his education from the friars in Vigevano, Bologna, and Genoa. An excellent and hardworking student, he was drawn to study Sacred Scripture and Saint Thomas Aquinas’ teachings. At age twenty-four, he was ordained a priest. For sixteen years, he taught theology and philosophy, formed Dominican novices, and served various friaries as prior. Father Michele deepened his prayer life, developed a strong devotion to Mary and the Rosary, made all-night vigils, embraced the Dominican charism, fasted, did penance, embraced poverty, and refused to engage in idle talk.
At the time, the Protestant Reformation divided European kingdoms, and the Church desperately needed reform to address financial abuses, nepotism, poorly formed clergy, poorly structured governance, theological debates, and lack of uniform liturgical worship. To address errors introduced by the Protestant Reformation, Pope Paul III reorganized the Italian Inquisition in 1542. Father Michele served on several inquisitorial missions, was made a bishop, and then a cardinal. In various Italian dioceses, he vigorously defended the true faith, weeded out heresy, corrected abuses, tightened Church structures, and lived out the life of faith and morals to which he was called.
When Pope Paul IV announced to his court that he wanted to make his fourteen-year-old nephew a cardinal, Bishop Michele firmly and successfully opposed him. Many of the cardinals admired him as a result, and in 1566, Bishop Michele was elected as the new pope, taking the name Pius V.
Just prior to Pius V’s election, the Council of Trent completed its final session, launching the Catholic Counter-Reformation that addressed theological and liturgical issues and sought to eliminate Church abuses. Pope Pius V was the man to implement the council’s decrees.
Pope Pius V continued to be a man of God. He acted not like royalty, but as a servant, wearing his one white Dominican habit (which is why the pope wears white today). Money for extravagant papal banquets was distributed to the poor. He visited the sick, built hospitals, and prayed twice daily before the Blessed Sacrament. The Papal States soon became more like a monastery than a kingdom.
Pius V reformed the clergy by mandating a seminary system, reaffirming celibacy, promulgating a new catechism for parish priests, attaching the clergy to one diocese, and exhorting bishops to remain in and serve their dioceses as true shepherds. He renewed discipline within religious houses and spoke out against immoralities within the clergy. He instituted catechetical classes for youth and introduced Saint Thomas Aquinas’ teachings in the universities. He spread devotion to the Rosary and promulgated a new Breviary and Roman Missal. He chastised, and even penalized, wayward rulers and defended Europe from Muslim invaders by helping form the Holy League, a cooperative effort of Catholic kingdoms within Spain and Italy, that included the Order of Malta.
Saint Pius V, you were unwavering in your faith and courage. God used those virtues to defend and reform His Church when it was suffering greatly. Please pray that as the Church continues to be in need of renewal and the Gospel in need of proclamation, I will be a holy instrument in the hands of God. May I be courageous and faithful until the end, no matter the cost. Saint Pius V, pray for me. Jesus, I trust in You.
