By the Grace of G‑d25th of Nissan, 5725Brooklyn, N.Y.
Mr....
Greeting and Blessing:
I am in receipt of your letter.
I wonder if your letter was written before, or after, the news of the Easter homily emanating from Rome reached here,1 followed by further news in the same vein.
You make reference to "artificial mechitza," implying that it would be brought about were inter-faith dialogue to be discouraged by Jews. But, as I indicated in my letter,2 our denial of inter-religious dialogue is not a matter of creating an "artificial" mechitza, but one of the fundamental precepts of authentic Judaism. For Judaism has not made it a doctrine to proselytize. On the contrary, Jewish Law places difficulties in the path of would be proselytes, and accepts them only most reluctantly. At the same time, however, Jews have never isolated themselves from the rest of the world, and have maintained communication with the outside world in a variety of spheres, other than religious.
You assert that the cutting off of inter-faith dialogue would be fatal to Judaism. I do not know on what basis you, of all people, make such an amazing statement. Certainly historically this has not been true. To be sure, there have been groups, sects and movements who sought to syncretize Judaism with other beliefs, religions or philosophies, beginning with the Calf worshippers soon after Mattan Torah, and their heirs, the Baal worshippers, the Saducees, Karaites, etc. But the fate of all these dissidents was sealed from the start: Either they returned to the fold, or they were completely severed from the Jewish people. Suffice it to mention that Christianity itself began as a dissident Jewish sect, but in time completely cut itself off from the Jewish people, and turned against it with growing animosity, to the extent of introducing the Inquisition, etc. Surely no further elaboration is necessary.
If there could have been any doubt as to the utility or futility of religious dialogue, at any time in the early history of our people, it should certainly be clear now, in the perspective of our long and eventful history, that any benefit claimed for interfaith dialogue is only illusory, while the harm of it is real and devastating.
With blessing,
Notes and sources
In Adar II of 5725, in response to the growth of the movement for Interfaith Dialogue, the Rebbe directed the Lubavitch News Service to broadcast and excerpted letter written in reply to the head of a group of Jewish spiritual leaders who had petitioned the Rebbe to express his opinion on the topic. The letter, which details the damage that such dialogue and debate would produce, the Halachic concerns in engaging in discussion of other religions, and the futility of such discussions producing their intended results, was widely publicized throughout the Jewish world, sparking much debate as to the persuasiveness of the Rebbe's argument. The Rebbe, in turn, received a number of responses containing questions, arguments, and challenges to the Rebbe's approach. To these, the Rebbe answered, refuting the arguments presented, and defending the thesis of his original letter. For more places where the Rebbe discusses his position, see source referenced in the above letter.

2) The abovementioned statement on the subject of "interfaith dialogue."
