The authors seek to identify the recurrent tensions, the blatant points of emphasis, the recurring indications of conflict and polemic. Framing the issue of the disposition of the Scriptural heritage in broad terms, they describe what characterizes the Gospels and the Mishnah, the letters of Paul and the Tosefta. In other words, if they take whole and complete the writings of first and second century people claiming to form the contemporary embodiment of Scripture's Israel and ask what they all stress as a single point of insistence, the answer is self-evident. Nearly every Christianity and nearly all known Judaisms appeal for validation to the Scriptures of ancient Israel, their laws and narratives, their prophecies and visions. To Scripture all parties appeal ― but not to the same verses of Scripture. In Scripture, all participants to the common Israelite culture propose to find validation ― but not to a common theological program subject to diverse interpretation. From Scripture, every community of Judaism and Christianity takes away what it will, but not with the assent of all the others.
