Explore Quick Facts ↓Maria Anna Donati was born on 26 October 1848 in Marradi, Florence, into a devout Catholic family. From an early age she showed a deep love for prayer and a desire to dedicate her life completely to God. As a young girl she spent considerable time with the Vallumbrosan Sisters, where she first sensed a vocation to religious life. Although her father opposed her entering a convent, this desire never faded.
Her spiritual life matured under the guidance of the Piarist priest Celestino Zini, who recognized her exceptional spiritual gifts and encouraged her to discern God's will with patience and confidence.
For many years Maria Anna postponed her religious vocation out of filial obedience, caring lovingly for her aging father after the death of her mother. Despite her longing to become a religious, she remained faithful to her family responsibilities until God opened the way for her mission.
In 1889, guided by Archbishop Celestino Zini, she founded the Calasanzian Sisters. At her religious profession on 24 June 1889, she received the name Celestina of the Mother of God, honoring her spiritual director and embracing a life entirely dedicated to Christ.
Blessed Celestina devoted her life to the educational vision of St. Joseph Calasanz, believing that every child deserved both education and Christian formation.
The Calasanzian Sisters focused especially on:
Under her leadership, the congregation established schools and charitable works that reflected the Piarist spirit of education rooted in faith, charity, and service.
Following the death of Archbishop Celestino Zini in 1892, she courageously assumed full responsibility for guiding the young congregation, leading it with wisdom, humility, and unwavering trust in Divine Providence.
Blessed Celestina lived a life marked by profound prayer, humility, and complete confidence in God. She believed that authentic Christian education begins with love and that every child is a precious gift entrusted to the Church.
Her spirituality was deeply inspired by St. Joseph Calasanz, whose educational ideals became the foundation of her congregation's mission. Those who knew her remembered her for her simplicity, maternal care, and unwavering dedication to the poor and abandoned.
Blessed Celestina continued guiding the Calasanzian Sisters until the end of her life. Through perseverance and faith, she witnessed the steady growth of the congregation and the expansion of its educational mission.
She died peacefully on 18 March 1925 in Florence, leaving behind a flourishing religious family dedicated to the service of children through education and Christian formation. Today the Calasanzian Sisters continue her mission in several countries, carrying forward her legacy of faith, education, and charity.
The Church officially recognized the holiness of Blessed Celestina through the process of beatification:
Her beatification followed the approval of a miracle attributed to her intercession.
Blessed Celestina of the Mother of God remains an inspiring example of:
Her life continues to inspire educators, religious sisters, and all who dedicate themselves to forming young people through faith, knowledge, and charity.
