Dr. Michael Horton has done an interesting book review of the book Kingdom through Covenant here. An excerpt:
For the seriousness with which it handles the issues, its depth of research and analysis, its approach on many issues, and the respectful description of alternative positions, Kingdom through Covenant strikes me as a model for the deeper and richer conversations that we need in our circles. However, since I'm offering a review from a traditional "covenant theology" perspective, I will skip over a host of edifying discoveries and get right to the point.
If I understand it correctly, the main argument of the authors is that dispensationalism and covenant theology both fail to read the Bible in a sufficiently typological way (pointing to Christ), though at different points: an unconditional and inviolable promise of either an ethnic people and geo-political land or of a "genealogical principle" that underwrites the baptism of covenant children and a "mixed body" ecclesiology. Consequently, covenant theology results in a one-to-one correspondence between circumcision and baptism, Israel and the church.
