Rev. Théodore Ratisbonne

Rev. Théodore Ratisbonne (1802–1884) was a French Catholic priest, convert, and prominent figure in the 19th-century Church. Born into a Jewish family in Strasbourg, he converted to Catholicism in 1826 under the influence of his studies and the witness of Catholic friends. Following his conversion, he felt called to the priesthood and was ordained in 1830.

Ratisbonne dedicated his life to Catholic education and evangelization, particularly focusing on fostering the faith among Jewish people. He co-founded the Congregation of Our Lady of Sion with his younger brother, Alphonse Ratisbonne, also a convert and priest. The congregation was dedicated to promoting understanding between Christians and Jews and to helping Jewish people discover the fulfilment of their faith in Christ.

Known for his deep spirituality and eloquence, Rev. Ratisbonne wrote extensively, producing works on theology, apologetics, and devotion, including History of Saint Bernard and other spiritual reflections. His writings reveal a profound love for the Church and a commitment to bridging divides with wisdom and charity.

Rev. Théodore Ratisbonne’s legacy lies in his pioneering efforts in interfaith dialogue and his profound dedication to the Catholic faith, inspiring generations through his life, ministry, and writings. His work with the Congregation of Our Lady of Sion continues to bear fruit in the Church’s mission of reconciliation and evangelization.
