Seeing as no mainstream well-informed religious jew would ever make a messianic claim about someone just because they are a tzaddik, I am in doubt as to whether the original poster is a mainstream well-informed religious jew, as opposed to possibly a evangelical christian, or simply a very misinformed jew. Everyone should be weary before responding to this. The evangelical christians really want mashiach to come for their own silly reasons, and have this crazy notion that the yenuka is that person since he’s been getting a large following.
As an aside, I am sure the yenuka is a tzaddik and talmud chacham, but I’m not sure why he would be different in this regard than any of the hundreds of other tzdikim and talmidei chachamim that have developed large followings.
Did anyone ever claim R’ Asher Weiss is mashiach? He is a tzaddik and talmud chacham whose large following is growing larger every year. How about R’ Chaim Kanievsky? Or maybe someone like R’ Elimelech Biderman who had a large following sprout very quickly? I could honestly go on, but אין להאריך בדברים פשוטים. I’m simply astounded by the question. Perhaps the questioner does know better and out of boredom was just trying to get people riled up?
