Nom…the chozeh of lublin never said “ko amar Hashem,” nor did he say he was a navi. He saw things in ruach hakodesh like tons of others.
You’re trying to make this into semantics. Nevuah is a definite phenomenon. It isn’t poetry like maskilim call it. It isn’t divine inspiration or ruach hakodesh. The rambam is clear about what nevuah is. Now i ask again, has anyone in the past 2000 years said “ko amar Hashem”, or any other such phrase, have they claimed to receive a direct communication from Hashem Himself? No. They have not. You’re trying awfully hard to avoid the idea that nevuah is no longer available today – why is that? Is it affinity for chabad? I don’t know why you’re beijg stubborn on this issue and marshalling unrelated sources, deflecting proofs by whisking away terminology, reframing the discussion into one of baalei mofsim and ruach hakodesh who see what is going on naachurei hapargod
Why not just admit it when someone has a strong taanah? It’s not that hard.
