Biblical Theology

How does the old covenant relate to the new?

Christians agree that the new covenant fulfils God’s promises in Christ, but differ over the degree of continuity between Israel and the church, the continuing role of Mosaic law, and the future of promises given to ethnic Israel.

The question

Where the disagreement lies

This debate is not simply a choice between continuity and discontinuity. Each reading preserves both in a different pattern: one covenant of grace under different administrations, distinct dispensations within one divine plan, or progressive covenants that reach their fulfilment and transformation in Christ.

Summary

Classic Reformed covenant theology sees substantial unity in God’s saving purpose. Promises, sacrifices, circumcision, and other old-covenant ordinances anticipated Christ; the new covenant administers the same grace with greater clarity and fullness. Ceremonial and civil laws expire with their redemptive-historical purpose, while the moral law continues.

What this contributes

This reading strongly unifies Scripture and the people of God while preserving development from promise to fulfilment. It explains why the New Testament can appropriate Israel’s Scriptures directly for the church.

Question to keep in view

Critics argue that the model can understate the newness of Jeremiah 31 or too quickly transfer promises made specifically to Israel to the church.
