One of the fundamental innovations of the early Church was the abolition of an ancient, venerable institution—divorce, the practice of which was as widespread as marriage itself. The explicit ban on divorce found in the Gospels ran counter to legal systems of the known world, with one notable exception: among the sectarian group whose rules are enshrined in the Dead Sea Scrolls, a stance against divorce can be verified, implying that a legal innovation of early Christianity can be tracked back to its origins in Sectarian Judaism.By the time Christianity was emerging, marriage and divorce had already co-existed for a long time; in Mesopotamia marriage contracts had for two millennia been anticipating the possibility of divorce, with litigation governing the dissolution of marriage and division of properties. The best evidence, however, for the precursors to late Hellenistic (i.e. pagan, Jewish, and Christian) legal practice derives from a group of Neo-Babylonian marriage contracts dating from the seventh to third centuries B.C.
