Reply To: Should we try to encourage Mashichists and Elokists to return to the fold?

When L Rebbe was paralyzed and moschihism was igniting, a local Rav called Rebbe’s secretariat and asked them how he can be of help in these difficult times. They asked him to publicize that this craziness is not coming from them. So, the Rav said it publicly. So, while this is not a direct testimony of what the Rebbe himself would think about it, but as close as it gets.
