If you want to start a new thread regarding Rabbi Dr. Lamm (and the “Speech”, feel free. Don’t hijack this one.
As far as the points (as per my understading of Rav Moshe Shapiro): Torah contains the blueprint of the briyah. “Nistakel B’Oraysah U’Bara Alma”. Some, like Avraham Avinu, were able to “reverse engineer” the Torah based on the Briyah. Some (for arguements sake, lets say Shlomo HaMelech) are able to understand the Briyah via the blueprint. Almost all (those not on the level of Avraham Avinu or Shlomo) are unable to understand one from the other. Therefore they need both sources, as they complement each other.
