Reddit mentions of The Unbroken Chain: Understanding the Mesorah of the Jewish Oral Tradition

There haven't been any discoveries that disprove Torah. There is a single letter difference in a Sefer Torah used by Sephardim vs by Ashkenazim, and the change doesn't impact the meaning. That's radically successful and unheard of anywhere else. Slight variations in Naviim or Kesuvim, which were written by humans, isn't too much of a challenge either. I'd recommend two books by Dovid Sapirman, Emunah: A Refresher Course and The Unbroken Chain: Understanding the Mesorah of the Jewish Oral Tradition. I'm not saying all his arguments are great, I had some problems with them, but it does really help understand how we know that Torah as we have it is the same Torah we got from HaShem at Har Sinai. We don't claim we know everything, or that we don't have room to learn more. But we do know for sure that we are operating from the same Torah that was given then.
