"HaKodesh Baruch saw we had passed the test of oppression. Despite all the tzaras, despite all the hatred, all the oppression, we remained loyal. There were a few Jews, meshumadim who sold their souls in order to get glory among the gentiles. There were a few. There were so few that they are insignificant. But Klal Yisroel passed the test. Now Hakodesh Baruch Hu said, I see you passed that test [of persecution in Medieval times]. I'm going to try you with another test now. [The test of emancipation in modern times.] Let's see how you work out this test. Now, when I said it was a calamity, it doesn't mean that the test was a waste, no. It was a minority that passed this test too. And those that remained loyal, they were a glorious example of the Am HaKodesh. Those that remain to this day. Many went lost, yes it's true. But an example, in Germany where there was so much assimilation, a number of German Jews decided they are going to fight for the preservation of the Torah. And they built up an Orthodox kehilla that was excellent in every detail. They were machmir in everything. In some respects, they were more frum than the Jews in Russia and Poland were. And they had organized kashrus. Strict hashgacha. Not rabbanim who gave heksherim and were paid for it. No. The kehillias gave hashgacha and were very strict in every detail. And so the minority that withstood the test were a glorious fulfillment of the prophecy that the Am Yisroel will continue forever despite any circumstances."
