Congregation of Our Lady of Sion
Catholic order of religious sisters

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". (Constitution, article 2).
Foundation
Religious brothers
The Ratisbonne brothers, who were Jews, were drawn to accept Christianity. For Théodore, this came about through the conversion of several close friends and the slow results of study and reading. He was baptized in 1826 and ordained in 1830.
Alphonse, however, was more reluctant to believe in Christ. This changed dramatically on 20 January 1842 in the course of a trip to Rome, made just prior to his planned wedding. While on a visit to the Church of Sant'Andrea delle Fratte, the Blessed Virgin Mary appeared to him. Both brothers believed that this was a sign from God, not only for Alphonse's personal conversion, but of their common call to bring their fellow Jews to accept the Christian faith.

Why this record matters
The subject matters to the general reference register because the source frames it as catholic order of religious sisters. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 15, 2026. The linked authority identifier is Q12409314. VIAF identifies the subject as 148997301. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1852, 1843, 1826 and 1830.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
