Saint Maria de Mattias
Foundress of the Suore Adoratrici del Sangue di Christ, Acuto, 1805-1866
Early life
Maria De Mattias was born on 4 February 1805 at Vallecorsa, in the province of Frosinone, the last village of the Papal States.[1] Her family lacked neither wealth, culture nor Christian faith, though women were forbidden to study.[1] Through conversation with her father, who read her the Scriptures from an early age, she developed a love for Jesus, the Lamb sacrificed for the salvation of humanity, while the village and its surroundings lived through the period of brigandage, 1810-1825.[1] Without schooling and without outside contacts because of her social class, at 16 or 17 she went in search of the meaning of her life.[1]
Vocation and foundation
In 1822, at 17, she saw the village transformed when San Gaspare Del Bufalo came to preach a popular mission at Vallecorsa, and the dream of doing as he did was born in her.[1] Having taught herself to read and write, she was called to run a school for girls by the administrator of Anagni, Giuseppe Maria Lais, and under the guidance of a companion of San Gaspare, the venerable Don Giovanni Merlini, she founded the Suore Adoratrici del Sangue di Christ at Acuto (Frosinone) on 4 March 1834, at the age of 29.[1] She did not limit herself to the school but gathered mothers and young women for catechesis; men, to whom she could not speak according to the custom of the time, came to listen to her, even in secret, and shepherds asked to be instructed by her after sunset.[1] Through the young women she drew, she was able to open about 70 communities, 3 of them in Germany and England, almost all in small villages of central Italy, except Rome, where Pius IX himself called her for the Ospizio di San Luigi and for the school of Civitavecchia.[1]
Death and recognition
She died in Rome on 20 August 1866 and was buried in the Verano cemetery at the wish of Pius IX, who chose her tomb and had a bas-relief of Ezekiel's vision made for it.[1] The beatification process began 30 years after her death, and she was beatified by Pius XII on 1 October 1950.[1] In the consistory of 7 March 2003 Pope John Paul II set the date of her canonisation for 18 May 2003.[1] She was canonised on 18 May 2003 by Pope John Paul II in St Peter's Square.[1]

Saint Maria de Mattias, also known as Mary de Mattias and Mary de Matthias, was born on 4 February 1805, in Vallecorsa, Frosinone, Papal States (modern Italy). She was born into a pious and educated upper-class family, where she acquired a deep love for her Catholic faith. Despite societal restrictions on formal education for women during her time, Maria's father ensured that she learned to read and write, as well as imparting much of her faith knowledge to her. As a young girl growing up in an isolated and self-involved environment, Maria began to feel a void in her life and yearned for more meaning. Seeking enlightenment, she fervently prayed and received a mystical vision that would transform her life.
In response to this spiritual calling, Maria made the courageous decision to leave her home and embark on a journey along the roads, spreading her knowledge and love of God to anyone willing to listen. At the age of 17, Maria attended a mission preached by Saint Gaspare de Bufalo. Witnessing the profound changes occurring in people who participated in the mission, Maria felt a deep desire to have a similar impact on others. With the help of Venerable Giovanni Merlini, she founded the Congregation of the Sisters Adorers of the Blood of Christ on 4 March 1834, in Acuto, Italy. This congregation focused on the education of girls, but Maria expanded their work to include teaching and catechizing women and boys.
Although societal norms prevented her from directly addressing men, Maria found inventive ways to reach them. Men would gather on their own, sometimes in secret, to hear her teachings. Pope Pius IX recognized Maria's exceptional leadership abilities and assigned her to oversee the San Luigi Hospice in Rome. From this position, she worked tirelessly to expand the reach and impact of the Adorers of the Blood of Christ congregation. Throughout her lifetime, Maria faced occasional opposition from some clergy members but enjoyed unwavering support from the laity. By the time of her death on 20 August 1866 in Rome, the congregation had established 70 schools, primarily in small isolated towns. By the time of her beatification, over 400 schools had been established by the Adorers.
Saint Maria de Mattias was venerated for her extraordinary virtues on 26 February 1936 by Pope Pius XI. Pope Pius XII beatified her on 1 October 1950, acknowledging her notable sanctity. Finally, on 18 May 2003, Pope John Paul II canonized Maria De Mattias at the Vatican Basilica, recognizing her as a saint of the Catholic Church. Today, Saint Maria de Mattias is honored as the patron saint of the Adorers of the Blood of Christ, an international religious congregation dedicated to following in her footsteps of serving God by fostering education, compassion, and the love of Christ. Her relics are venerated in Rome at the Church of the Precious Blood, and her feast day is celebrated on 20 August each year.
