Rav Eliezer Melamed has recently been criticized harshly by leading rabbis from the right wing of Religious Zionism. This affords an opportunity to introduce Rav Melamed and his ongoing magnum opus, Peninei Halakha. In this first episode, I detail who he is, what the Peninei Halakha project is, and where it fits in the history of halakha. The upshot: His is the first successful reorganization of practical halakha in almost 700 years!
