life. The congregation was named after the companion of Paul. In 1534 at St. Catherine's, he popularized the Forty-hour devotion for the laity – the solemn exposition of the Blessed Sacrament for adoration by the faithful – accompanied by preaching. In July 1535 Pope Paul III, with a Bull of approbation, confirms the devotion to Saint Paul for Zaccaria and his group. While on mission to Guastalla in 1539, he caught a fever. Combined with the strict penances he performed, his health worsened and he died on 5 July 1539, at the age of 36. The suffragan bishop, Luca di Seriate, who had ordained him a priest, presided over his funeral. In attendance were the aristocrats and people of Cremona and the surrounding towns. He was buried in the San Paolo Convent of the Angelics of Saint Paul, the female branch of the Barnabites, in Milan. In his last will and testament, Zaccaria stipulated the construction of a chapel in honor of the Conversion of Saint Paul in his parish, Saint Donato. Foundations While in Milan, he laid the foundations of three religious institutes: one for men (the Clerics Regular of Saint Paul, commonly known as the Barnabites); a female branch of uncloistered nuns, the Angelic Sisters of St. Paul; and a lay congregation for married people, the Laity of Saint Paul, originally called the Married of Saint Paul (sometimes called the Oblates of Saint Paul in North America). The three foundations met regularly, and engaged together in various forms of apostolic action. Their aim was the reform of decadent society, beginning with the clergy and religious. The Clerics Regular of St. Paul (the Barnabites) "The Congregation of the Regular Clerks of St. Paul" was canonically sanctioned by Pope Clement VII in 1533. Since the order criticized what they saw as abuses in the Church, Zaccaria soon gained a number of enemies, and as the order's founder, he was twice investigated for heresy, in 1534 and 1537. He was acquitted both times. In 1536, he stepped down as General of the Order and went to Vicenza, where he reformed two convents and founded the Order's second house. The Angelic Sisters of St. Paul On January 15, 1535 Pope Paul III approved the Angelic Sisters with the Bull, Debitum pastoralis officii. On February 27, 1536 Zaccaria conferred the habit on six postulants of the Angelic Sisters. Zaccaria appointed Paola Antonia Negri
