(JTA) — BUENOS AIRES — Argentina’s Sephardic chief rabbi reaffirmed a 100-year-old ruling that conversion may not be performed in Argentina and is considered valid only if carried out in Israel.

Representatives of non-Orthodox movements reacted angrily, asking why the ruling was issued now and saying it would essentially subject Argentinian converts to the tight hold that Israel’s Orthodox rabbis have on conversion.“Orthodoxy is attempting to present itself as the sole legitimate source of Judaism and halachic [Jewish legal] authority,” Rabbi Ariel Stofenmacher, the rector of the Seminario Rabínico Latinoamericano, the Masorti/Conservative movement’s seminary in Buenos Aires, told JTA.  “We are concerned that members of the Jewish community in Latin America, where about 80 percent or more are not Orthodox, may read that statement by an important rabbi and feel confused.”

The document, issued on Jan. 13 and signed by Chief Rabbi Yosef Chehebar, reaffirms a takanah, or rabbinical ban, first established in Argentina in 1927. The authors of that ban, Rabbi Shaul Sitehon Dabah of the Syrian-Aleppo tradition and the Ashkenazi Rabbi Aharon Goldman, emerged in response to a proliferation of lax or irregular conversions, particularly in rural areas among Jewish immigrants.

The statement signed by Cheheber describes the ban as “general and binding.” It emphasizes that the decree was enacted permanently, “with no temporal limitation or expiration whatsoever,” and frames it as a safeguard for “the purity of lineage and the sanctity of our families.”

In the years since the original ban, however, non-Orthodox rabbis say the conversion process has been standardized, and that the level of preparation in Argentina is considered very high. The Masorti seminary, which has conducted conversions since its founding in 1994, argues that the reasons for the restriction “are no longer applicable.”

Critics of Cheheber’s document say there have been no recent incidents or developments that would have prompted such a reminder.

“We reject recent statements that invoke a cherem from the 1920s to invalidate conversions carried out outside the State of Israel and by non-Orthodox rabbis, as well as the use of language that appeals to notions of ‘lineage,’ ‘purity’ or ‘contamination,” the Seminario Rabínico Latinoamericano and its affiliated Rabbinical Seminary said in a statement Jan. 15. “Such claims are halachically unsustainable and ethically unacceptable, particularly when they introduce categories alien to Judaism and morally offensive.”

Rabbi Isaac Sacca, the Sephardi Chief Rabbi of Buenos Aires, posted Chehebar’s ruling on social media and defended it in an interview with JTA.

“The regulation represents a self-imposed limitation by Argentina’s Orthodox rabbis on their own authority, undertaken in order to ensure security and peace of mind that a practice as delicate and sacred as conversion is carried out with due seriousness, and that neither the convert, nor families, nor the community are misled,” he said.

Conversion has been a flashpoint between the diaspora and Israel, where the Orthodox rabbinate for decades held a near monopoly on Jewish lifecycle events, including conversion. Non-Orthodox conversions were recognized in Israel under a landmark ruling handed down by the Israeli Supreme Court in 2021,  but non-Orthodox groups continue to object to government regulations that complicate the recognition of these conversions.

Conversion has been particularly fraught in Latin America, including the controversies that led to the 1927 takanah and, more recently, the mass conversion in Brazil, Colombia and other countries of people who identify as Bnei Anusim — descendants of Jews forcibly converted during the Spanish and Portuguese Inquisitions.

Within Orthodox circles in Argentina, preparatory stages for conversion may take place in the country, but the bet din, or rabbinical court, that validates them operates in Israel. According to sources who asked to remain anonymous, the target of the latest ruling was not the non-Orthodox movements but Orthodox rabbis who had been offering more flexible alternatives to prospective converts, such as completing an Orthodox conversion in neighboring Uruguay and then returning to Argentina to seek its recognition in Buenos Aires.

Chehebar’s recent statement specifies that the takanah “applies both to any person residing in Argentina, as well as to anyone coming from another country with the intention of establishing residence in national territory, even in cases in which the giyur [convert] has already been carried out in their country of origin or another country, outside of Eretz Israel.”

Asked whether any specific incident had triggered the statement, Sacca replied: “We are not aware of any particular event. It is simply a reminder that the Sephardic Chief Rabbinate of Syrian-Aleppo tradition has conveyed to our rabbinate for public dissemination.”

The ruling “does not constitute a rejection of the convert, nor does it devalue those who sincerely seek to join Judaism,” he added. “On the contrary, it functions as a halakhic safeguard designed to preserve a core commandment linked to Jewish identity, in a context marked by social pressures and institutional weaknesses. It also seeks to prevent hasty decisions that could affect the spiritual and personal lives of those seeking conversion, as well as those of their descendants.”

The Masorti movement insisted that its own rabbis conduct the conversion process in a manner that is “serious, demanding, and deeply Jewish,” based on rigorous study, commitment to Jewish life and responsible rabbinical guidance. “Those who join the Jewish people through this path,” the statement affirms, “are received as full Jews, with dignity and complete belonging, in accordance with rabbinic tradition.”

Said Stofenmacher: “We reaffirm that we conduct legitimate conversions in accordance with the halacha, as we have done for decades, with thousands of individuals who have joined the Jewish people in our region, and we will continue to do so in all the communities where our rabbis serve.”
