In this final class in the System of Halacha series, we will explore the nature of the halachic process itself. When a Jew today asks a question of a competent authority in Jewish law, what stands behind the answer he or she is given? We will further examine key stages, rabbis and legal codifications that have developed throughout the chain of Torah transmission, as discussed in the fifth System of Halacha class. We will thus gain insight into the underpinnings and dynamics of the halachic process. Finally, we will illustrate the halachic process by looking at a typical example, namely, the contemporary question on whether one can fulfill the mitzvah of bikur cholim (visiting the sick) via the telephone, email, or Skype.
