Moshe Ben Haim is not an "Orthodox Rabbi". He is a complete ignoramus often dipping into the realm of complete heresy.
He is not Conservative or Reform.
I think he calls himself Rabbi and I have no reason to believe he is lying.
If he is a rabbi, and i'm sure he is, then he is an Orthodox one for sure.
I would bet that he accepts ALL of Maimonides 13 principles of faith.
He does pick on Chabad (your group), which I think is inconsistent of him and I suppose are an easier target for him than other kabbalists such as the Arizal, the RAMCHAL, the Vilna Gaon.
He rejects many mystical doctrines such as the one of Tzim Tzum and G-d is everywhere.
Funnily enough, I think the idea of G-d being everywhere may be stronger in Misnaged kabbalistic thought than in Chassidic. Though most misnagdim are not as into kabbalah.
I heard a very lucid description of tzim tzum from a misnaged, he said that G-d is everywhere literally.. And constricted his presence so we cannot sense him. The world is his garment. Lest one think we should pray to objects, we don't pray to objects because a)it is as when one addresses a person ,if one speaks into his ear, he is not speaking TO his ear. If one speaks towards a person's coat he is not speaking TO the coat. So too, in this material world are like his garments. b)we worship him in the way that he told us, by keeping mitzvot.
The chassidic view from what I understand, is G-d's light is everywhere. (not G-d himself?).
He rejects the whole thing. And that's fine. I don't see how the chassidic one contradicts the RAMBAM, though it's not supported by it.
He holds firm to the RAMBAM who says in Hilchot Yesodai HaTorah. G-d has no left or right associated with him..
I have heard this idea that G-d is ALL, there is a great description by Gil Locks (beware, you may get dizzy listening to him, but it's somewhat of a rite of passage!). He does bring a few verses from tenach to try to support it.
This idea does appear to me to contradict the RAMBAM though. This rabbi is convincing in his argument there.
Most misnagdim now, maybe 'cos they are not that into kabbalah, would only say that G-d can be found everywhere, but wouldn't say G-d is everywhere. Same as chassidim I -think- perhaps. I don't think he counters that idea really. He would agree G-d can be found everywhere. G-d fills the earth with his glory.. His presence perhaps, the earth, but not G-d himself.
It is not HERESY to reject All kabbalah post talmud. Most think that the RAMBAM did. Most think that the RAMBAM was -not- a kabbalist.
Fine, he lived in a different era, but still he's not a heretic if he didn't believe it, and it's ridiculous to say that the RAMBAM were he around today, -as we know him- no signs of kabbalah, it's ridiculous to say he would be a heretic.
There are some jews, who hold strongly to him. Not this guy, some people reject more than this guy. And they would not accept kabbalah either.
There is this group, who are VALID, they are orthodox. Just not the kind of orthodoxy we have grown accustomed to, not the mainstream.
http://en.wikipedia.org/wiki/Dor_DaimRabbi Kapach / Qafah, is well respected, I think even outside his Maimonidean group.. But he rejects the Zohar, and if he rejects that, you can be sure he rejects chassidut too.
It's not heresy. But it's far from the mainstream, and one wouldn't normally encounter these people in real life! But they are out there. Somewhere! In some synagogues in israel for example.
http://www.torathmoshe.com/this guy has some youtube videos available. He is not a typical representative though. he has an interest in theology, and converted.. and doesn't seem to target many videos to jews unfortunately. But he's a smart guy and it looks kosher.
