ABSTRACT: The New Testament authors quote, allude to, and interpret the Old Testament in a great variety of ways — and sometimes in ways that seem illegitimate to modern readers. But the apostles’ use of the Old Testament becomes clearer as we grasp the distinct practices and postures they brought to the Scriptures. Such practices and postures reveal not only how the apostles understood the Old Testament, but also how it shaped and saturated everything they wrote. In the end, the apostles not only thought about and interpreted the Old Testament; they also thought with and through the Old Testament and were interpreted by it.
