Charles of Sezze (19 October 1613 – 6 January 1670) - born Giancarlo Marchioni - was an Italian professed religious from the Order of Friars Minor. He became a religious despite the opposition of his parents who wanted him to become a priest and he led an austere life doing menial tasks such as acting as a porter and gardener; he was also a noted writer. He was also held in high esteem across the Lazio region with noble families like the Colonna and Orsini praising him and seeking his counsel as did popes such as Innocent X and Clement IX.
His beatification was celebrated in 1882 while Pope Pius XII approved his canonization in 1958; but the pope died before he could canonize the friar so his successor Pope John XXIII did so on 12 April 1959.
Life
Giancarlo Marchioni (also known as Charles) was born in Sezze on 19 October 1613 to the poor farmers Ruggero Marchioni and Antonia Maccione. His baptism was celebrated on 22 October 1613. His mother - when he was a toddler - liked to dress him in a dark tunic with a cord and hood in honor of friars Francis of Assisi and Anthony of Padua and she kept this 'habit' even after he outgrew it.
His maternal grandmother Valenza Pilorci instilled devout practices and other religious values within him in his childhood. He worked on the farm as a shepherd to help his parents with the exhaustive workload and liked to plough in the fields because he liked the oxen. He made a private vow to remain chaste in 1630 and in 1633 fell ill to the point of near death that he pledged to join the Order of Friars Minor if he were to be healed of his ailment. His parents encouraged his call to become a priest, though he was a poor student and largely illiterate, leaving seldom hope of his excelling in advanced studies.
He felt a desire to serve in the missions in India and later became inspired from the lives of Pascal Baylon and Salvador of Horta - who were both professed religious. Marchioni was admitted into the order at the San Francesco convent in 1635 at Nazzano; he received the habit of the order on 18 May 1635. He later recounted that he did so out of a desire to live a poor life and to beg alms "for the love of Christ". He again set his heart on the missions but poor health halted this dream.
He lived the life of a religious and never requested ordination to the priesthood despite the protests of his parents to do so. He made his solemn profession into the order on 19 May 1636 into the hands of Father Angelo Maria and his religious name was "Cosmas" at first but his mother's insistence saw it changed to "Carlo". He worked at a range of jobs in various friaries: he cooked and served as a porter and also worked as both a sacristan and gardener; he also went out into the streets as a beggar. He was not qualified in all of them as he became notorious for setting the kitchen of one house on fire. From 1640 to 1642 he was stationed at the convent of Saint John the Baptist at Piglio and at San Francesco at Castel Gandolfo. In October 1648 he attended Mass at the church of San Giuseppe a Capo le Case and a beam of light emanated from an elevated Host that pierced his side and left a visible open wound at his side.
On one occasion the guardian of a convent ordered him - who was the porter at the time - to give food to traveling friars who came to the door. He did this in obedience and alms to the friars decreased. He persuaded the guardian that the two facts were related. Once the friars resumed giving help to all who sought assistance at their door alms to the friars increased. Though he was not a priest he was instructed to write the account of his life after his confessor requested it of him. The result was "The Grandeurs of the Mercies of God" which was well-read; he went on to write several other books. Though he kept himself under the guidance of a spiritual director he himself - though not a priest - was often sought for spiritual advice and even Pope Innocent X and Alexander VII sought him out for advice. In 1656 he tended to victims of cholera at Carpineto. On 22 August 1664 he was at San Pietro in Montorio when he fell ill with malarial fever and so was taken to San Francesco a Ripa to recuperate; he recovered on 30 August after bed rest was prescribed to him. On 28 July 1665 he had a vision of Pope Victor I and Teresa of Ávila.
