Introduction
This article—based extensively on the research by Professor Bernard Dov Cooperman[1]—explores how the Italian rabbinic world dealt with their dynamic differences in theological expression during the early Modern period. This was about the same time as R. Yosef Karo was producing his Shulchan Aruch in Safed. If one of the rabbis stepped out of the perceived appropriate theological boundaries, they were officially placed under a ban of cherem, or excommunication. However, what they referred to as cherem differs dramatically from the way we understand and implement the concept of cherem today. The earlier forms of excommunication and even charges of heresy were not as severe or even as binding as they are considered nowadays.
