The Rebbe's Position on Eruvin and Carrying in Large Cities
The Rebbe wrote that an eruv should be established where it can be made according to halacha. His city-eruv correspondence then sets demanding conditions for applying that principle: the particular city must qualify, the matter must be handled by Rabbonim with expertise in Hilchos Eruvin and knowledge of the local facts, and the public consequences of announcing the eruv must be considered before people are encouraged to carry.
Publicity was a recurring concern. Once an eruv is announced, families arrange their Shabbos around it and carrying becomes normal. If the eruv later becomes invalid, a notice may never reach everyone who has come to rely upon it. In several letters, the Rebbe therefore discussed a concealed eruv whose purpose was to reduce the severity of carrying already taking place, while opposing its use as a public permission to carry.
Crown Heights has its own account. Rabbi Yehuda Leib Groner wrote that the Rebbe strongly opposed making an eruv in Crown Heights and had said on several occasions that no one had permission to make one there. The Chitrik family later related that Rabbi Hirshel Chitrik was told not to build a Crown Heights eruv unless it would remain hidden. These accounts concern the Rebbe's neighborhood directly and accord with the distinction stated in his own letters between a concealed enclosure and a publicly relied-upon city eruv.
The Rebbe distinguished between three different questions
The starting point is a letter the Rebbe wrote in English to Rabbi Eliyohu Jung on the first day of Chol Hamoed Pesach 5724, concerning the proposed Manhattan eruv. The Rebbe began with a principle:
"Firstly, as a matter of principle, where according to the Din an Eiruv can be instituted, it should be so instituted."
The same letter immediately turns to two further questions: the danger of public reliance on an eruv that may later fail, and the need for competent Rabbonim to decide whether the particular place qualifies.
The letter gives a clear order of inquiry:
- A place must first be shown to be suitable for an eruv according to the relevant halachos.
- That determination belongs to Rabbonim who know Hilchos Eruvin and have investigated the actual local conditions.
- Even after those conditions are satisfied, the consequences of publicizing the eruv remain a separate concern.
The Rebbe returned to these distinctions in different forms over many years.
A large city must be judged according to its actual halachic facts
Large-city eruvin involve questions that do not arise from the mere existence of poles, wires, walls, or a mapped boundary. The status of streets as a reshus harabim, the significance of shishim ribo, the form and openness of the streets, existing mechitzos, waterfronts, bridges, tunnels, and other physical conditions all have to be evaluated according to halacha.
This is visible already in the Rebbe's correspondence in the 5710s. In a letter of 15 Iyar 5714 to Rabbi Tzvi Hirsch Eisenstadt, the Rebbe enclosed detailed notes on a proposal concerning eruvin and addressed particular halachic points rather than treating a city by label alone. A later letter to Rabbi Yosef Dovid Moskowitz likewise discusses specific questions of enclosure and then separately addresses publicity.
The same approach appears in a public sicha on Yud-Beis Tammuz 5745. The Rebbe referred to the halachic discussion of cities in which 600,000 people pass through a main street. He described a case in which an actual count showed that the number was present, despite an older factual assumption that such a situation did not exist. The Rebbe's conclusion was direct:
"Clearly, however, the Halachah must be that this really is a 'public domain,' for the reality can't be denied."
The city in that passage was not named, and the sicha was not presented as a psak about Crown Heights. Its importance is the principle it states. A halachic application cannot rest on an old factual assumption when the present reality is different. Questions such as shishim ribo therefore require an examination of what the relevant halachic measure is and what the current facts actually are.
An eruv in a city requires a Rav expert in these halachos
The Rebbe was equally explicit about who may undertake such a project. In a response dated 3 Tammuz 5722, written to Rabbi Pinchas Weberman, he addressed "an eruv in a city" and wrote, in translation:
Since there are many halachos involved, this should not be done without the participation of a Rav who is particularly expert in these halachos.
Expertise in the general subject is only one part of the requirement. The Jung letter explains that a general principle favoring an eruv where halacha permits one does not decide whether a particular city actually qualifies:
"This is a matter to be decided by the Rabbinical authorities who have thoroughly investigated the pertinent details in full accord with the Hilchoth Eiruvin."
A city eruv cannot be established by beginning with the desired result and then applying general rules from a distance. The relevant Rabbonim must know the halachos and the local facts to which those halachos are being applied.
Publicizing an eruv was a separate and serious concern
The Rebbe repeatedly addressed what happens once a public has been told that it may carry.
In the 5724 Jung letter, the Rebbe contrasted an earlier period, when a small and closely connected Jewish community could quickly learn that an eruv had become invalid, with contemporary city life. The existence of an eruv could become widely known, while news that it had failed might reach only people in regular contact with Rabbonim or shuls. Even some who heard that the eruv was down might already have become accustomed to carrying.
The Rebbe therefore wrote:
"the Eiruv, if one is feasable at all according to Din, should be carried out in the utmost secrecy."
He then explained what such secrecy meant. The purpose would not be to enable a person to carry a tallis to shul on Shabbos. It would be to reduce the issur for people who were already carrying regardless. In other words, the concealed eruv contemplated in that letter was not a public heter around which ordinary Shabbos life would be organized.
The same concern appears in Igros Kodesh, in the letter of Rosh Chodesh Adar 5718 to Rabbi Yosef Dovid Moskowitz. After discussing the eruv itself, the Rebbe wrote in emphatic terms that it should not be printed or otherwise publicized that the eruv had been completed. He explained that publicity could lead observant Jews to find grounds to permit carrying for themselves, and that after the matter had become public the resulting breach might no longer be repairable merely by warnings.
Later responses concerning Melbourne and a proposed publication in Yagdil Torah return to the same distinction. Their full circumstances differ, but the recurring concern is recognizable: a city eruv that becomes publicly relied upon creates a problem beyond the technical question of whether some enclosure can be arranged.
A hidden eruv is not the same thing as a public carrying eruv
The word "eruv" can refer to two very different practical arrangements in the later accounts of conversations with the Rebbe.
One is a public community eruv. Its boundaries are advertised, people are told they may rely on it, families plan their Shabbos carrying around it, and a broad public must be notified whenever it becomes invalid.
The other is the kind of concealed eruv described in the Jung letter. It is deliberately not publicized as permission to carry. Its purpose is limited to reducing the severity of carrying already being done by people who will carry whether or not an eruv exists.
The Rebbe's own letter makes that difference explicit. It is also the key to understanding the Chitrik family account about Crown Heights.
Crown Heights
The Crown Heights-specific record is not a published letter of the Rebbe naming the neighborhood. It is preserved chiefly in named testimony from people close to the events, read against the Rebbe's direct written position on city eruvin.
In May 2016, Rabbi Yehuda Leib Groner issued a written statement after being asked about the Rebbe's position on constructing an eruv in Crown Heights. He wrote:
"The Rebbe strongly opposed making an Eiruv in our community, and he reiterated on several occasions that no one has permission to make an Eiruv here."
Rabbi Groner also referred to the Melbourne question and said that the Rebbe's response there had been to oppose the proposed eruv forcefully. His Crown Heights statement is testimony by the Rebbe's longtime mazkir about what he heard and understood from the Rebbe. It is not presented as a Rebbe-authored letter.
A separate family account concerns Rabbi Hirshel Chitrik. In a public 2023 discussion, a grandson said that he had heard from his grandfather several times that Rabbi Chitrik asked the Rebbe about building an eruv in Crown Heights so that his wife could go to shul with their young children. According to the grandson's account:
"The Rebbe told him that he should not build an eruv in Crown Heights unless it's going to be hidden."
The grandson explained that a concealed eruv would not accomplish the family purpose for which Rabbi Chitrik had asked, because it could not be announced for public reliance. He said this was why his grandfather did not build it. He also related a later, independent recollection from his grandmother that the Rebbe had told them not to build an eruv.
The wording survives through later family testimony, not through a recording of the original conversation. But its substance fits closely with the distinction stated in the Rebbe's own Jung letter: a concealed eruv intended to reduce existing aveiros is not the same as a public neighborhood eruv that permits people to carry as a matter of ordinary practice.
The written sources and the Crown Heights accounts
The letters to Rabbis Jung, Moskowitz, Weberman, and Eisenstadt are the Rebbe's own correspondence. They address the halachic eligibility of the particular place, the need for expert rabbinic authority, and the problems created by publicizing a city eruv.
The Yud-Beis Tammuz 5745 passage is a recorded public sicha. It establishes the Rebbe's insistence that present factual reality controls the application of halacha, including in a case involving 600,000 people and reshus harabim.
Rabbi Groner's 2016 statement is his written account of the Rebbe's position in Crown Heights. The Chitrik account is later oral family testimony reporting what Rabbi Hirshel Chitrik said the Rebbe had told him. Both concern a public eruv in Crown Heights; neither is presented as a Rebbe-authored letter or a recording of the original conversation.
The practical Crown Heights ruling belongs to the Rabbonim of Crown Heights. The Rebbe material explains an additional part of the history: the general city-eruv principles he stated directly, and the neighborhood-specific position transmitted by those who were involved with him.
