At this point I don’t think it’s highly speculative to say that a great divide is being drawn between those whose desire to not cut themselves off from non-jewish ideology has not, until recently, put them at total odds with halacha, and those who are using the Torah as their sole guide and defining factor..
20 years ago it was easier to be a practicing Jew who thought similarly to non jewish counterparts; today it is completely impossible. Something has to give – it’s either Hashem or the ba’al; it is precisely like Eliyohu on Har Karmel…ad mosai atoh posayach al shtei haseifim…
The rizhiner rebbe said that before moshiach there will be such an event as with Eliyohu, only that the fire will come down on the side of baal.
