Lengthy letter (approx. 33 lines) handwritten and signed by Rebbe Yitzchak Zelig Morgenstern Rabbi of Sokołów. Sokołów, [1930]. Written on the second leaf of the printed invitation to the wedding of his daughter, Sarah, with R. Binyamin Morgenstern son of R. Yaakov Aryeh Rabbi of Wyszków. Letter with particularly significant and noteworthy content, addressed to R. Tzvi Hirsch Farber, a foremost London rabbi. The Rebbe writes against the government's initiative to entrust the authority over ritual slaughter and Kashrut to the Chief Rabbi of the British Empire. The letter also reveals an interesting insight imparted by the Chatam Sofer. The Rebbe begins with enjoining R. Tzvi Hirsch and the rabbinical council to express their vehement protest on this matter, to the point of instructing the Orthodox rabbis who are members of the Chief Rabbinate, not to collaborate with this scheme, as they are required to have foresight. The grounds for the objection are firstly, the unfeasibility of governing the Kashrut of the entire country, and mainly, since there is no guarantee as to what kind of rabbis and Chief Rabbi will later be instated. He relates that the government bade the Chatam Sofer to become the chief rabbi of Hungary, with authority over the rabbinate and all religious matters, yet the Chatam Sofer categorically refused to accept this position, contending that he did not know who his successors would be. The Rebbe later in the letter relates of a similar issue which was raised in the famous Rabbinical Congress in St. Petersburg in 1910, in which the Rebbe participated as a representative of Poland, together with other leading Polish rabbis. On that occasion, all the rabbis unanimously ruled against delegating all religious affairs to a special committee of rabbis, arguing that one cannot foresee who would later succeed them. They recalled the controversy which arose in France, when the government wished to give the Chief Rabbinate the power to liberate Jewish women from their marital status, just like priests in other faiths are authorized to release women from their husbands. The Rebbe then mentions how the Orthodox rabbis in Kovno are campaigning against the institution of a chief rabbinate controlling all religious affairs. Consequently, the London community, who already have a Chief Rabbinate and can see for themselves the power they hold, must endeavor to dissuade the government from assigning the Chief Rabbinate the Kashrut institute, upon which the holiness of the Jewish people rests. "Surely, your government, which upholds religious freedom, will not force upon you this unnecessary institution, and may G-d be with your mouths… One who writes for the sake of truth and religion - Yitzchak Zelig Morgenstern Rabbi of Sokołów".
