 Rabbi Zweig is in fact the only Orthodox rabbi on the 100+ member Board of Directors of the Greater Miami Jewish Federation, and one of only four rabbis in total on the Board (the others being Rabbi Jonathan Berkun (Conservative), Rabbi Mario Rojzman (Conservative) and Rabbi Alan Litwak (Reform)).Rabbi Zweig approaches Talmudic study with an emphasis on originality and personal understanding.While accepting the approaches of the earlier commentators (known as "Rishonim", as opposed to "Achronim" (later commentators)), Rabbi Zweig brings a fresh perspective to each Talmudic topic that relies on a critical and literal reading of the passage.
