Blessed Maria Theresia Scherer was a Swiss religious sister and co-founder of the Sisters of Mercy of the Holy Cross, remembered for her dedication to the sick, the poor, and the marginalized in nineteenth-century Europe. Born Anna Maria Katherina Scherer on October 31, 1825, in Meggen near Lucerne, Switzerland, she was the fourth of seven children in a poor farming family. Her father died when she was seven, after which two uncles helped raise her with a strong Christian education. Known as the Sunny Child of Meggen for her cheerful disposition, she showed early compassion for the suffering and began working in hospitals at age sixteen.
A pilgrimage to the shrine of Our Lady of Einsiedeln in 1844 deepened her sense of vocation. The following year, at seventeen, she joined the Teaching Sisters of the Holy Cross, a new congregation founded by the Capuchin priest Theodosius Florentini. She received the habit and made her first vows on October 27, 1845, taking the religious name Maria Theresia. She taught in several schools and later served as superior of a hospital in Chur, where her practical skills and deep faith stood out.
In 1856, together with Father Florentini, she co-founded the Sisters of Mercy of the Holy Cross in Ingenbohl, shifting the focus toward works of mercy such as caring for the sick and orphaned. Elected the congregation’s first superior general in 1857, she held the position for thirty-one years. Under her leadership the community grew despite financial debts, opposition, and hardships. She oversaw the establishment of hospitals, homes for the poor, and other charitable institutions, always emphasizing prayer, humility, and selfless service. Her interior life, marked by long hours before the Blessed Sacrament, sustained her through trials.
Mother Maria Theresia died on June 16, 1888, in Ingenbohl after a painful illness, reportedly uttering the words Heaven, Heaven as her final utterance. Her cause for sainthood advanced steadily. Pope John Paul II declared her venerable in 1993 and beatified her on October 29, 1995, in Saint Peter’s Basilica. Today her feast is observed on June 16, and the congregation she helped establish continues its mission in many countries, carrying forward her legacy of mercy rooted in profound trust in God.
