“The Ways that Never Parted” is the title of a recently published collection of articles that reflects an increasing tendency in scholarship. A significant number of scholars no longer interpret the emergence of Christianity from Judaism as a clear separation between the two religions either at the end of the first or the beginning of the second century. Instead, they envision a prolonged process which, according to some, may even have lasted until the late fourth century. This process is thought to have been shaped by both segregation and rapprochement, creating ambiguity and “fuzziness” rather than clear boundaries. A central notion is the idea of sororal relations between Judaism and Christianity. These scholars no longer see Judaism as the mother figure giving birth to the daughter religion, while remaining unchanged herself, but rather as a sister developing and changing during the first centuries of the Christian era. This interpretation then sees Jews as an integral part of the Roman Empire, which eventually became Christian and (im)posed certain religious challenges.
