The early church received the Scriptures of Israel as Christian Scriptures and did not change them. The older testament was received as a witness to God, and when a newer testament emerged, the older was not dismissed, harmonized, or edited. Rather, the church moved forward with a two-testament witness.

Christopher Seitz, an internationally renowned expert in canonical interpretation, illuminates the two-testament character of Scripture and its significance for the contemporary church. He interacts critically with current interest in the New Testament''s use of the Old Testament and addresses an issue of perennial concern: how to hear both testaments as Christian witness.
