Congregation of Our Lady of Sion

The Congregation of Our Lady of Sion (French: Congrégation de Notre-Dame de Sion, abbreviated NDS) is composed of two religious congregations in the Roman Catholic Church founded in Paris, France. One is composed of priests and religious brothers, founded in 1852, and the other is composed of religious sisters, founded in 1843, both by Marie-Théodore Ratisbonne, along with his brother Marie-Alphonse Ratisbonne, "to witness in the Church and in the world that God continues to be faithful in his love for the Jewish people and to hasten the fulfillment of the promises concerning the Jews and the Gentiles".
