Feliksa Kozłowska

Feliksa Magdalena Kozłowska, known by the religious name Maria Franciszka and the epithet "Mateczka", was a Polish religious sister, Christian mystic and visionary who founded a movement of renewal in the Roman Catholic church in the Congress Kingdom of Poland. It was to follow the simplicity of the life of Mary, mother of Jesus. Early in the 20th century, she and this movement were excommunicated and became an autonomous church in fellowship with the Old Catholic Church of the Netherlands. In 1935 it split in two and became the Old Catholic Mariavite Church and the Catholic Mariavite Church. Both denominations were part of a single schism from the Catholic Church which declared it as heretical in 1906.
