The Maria Sorg Mission in Lengfelden served as the base for much of the work that was done by Maria Theresia Ledóchowska. From the end of the 19th century, she attempted in many countries throughout Europe to awaken interest in African missionary activities.
She strove to provide assistance to all missionaries, regardless of their denomination or nationality.
Although she was never in Africa herself, she was lovingly known by the missionaries and Africans as "their mother".
To this day, nuns live and work at the Mission, still doing what they can to support missions in sore need of assistance.
"It is my life's task, and that of the society to which I belong, to expand more and more the interest in missionary work and, when possible, to plant the missionary seed in all hearts."
(the Blessed Maria Theresia Ledóchowska, Wien 1913)
