Beckwith on the Relationship between the Testaments
In his magnificent book, The Old Testament Canon of the New Testament Church, Roger Beckwith writes (408):
The church was, of course, given its own authoritative interpretation of the Old Testament by Jesus and the apostles, but since Christianity was a thorough-going prophetic movement, claiming a new outpouring of the Holy Spirit, withdrawn when prophecy ceased, the writings in which this interpretation was incorporated formed not just an appendix to the canon but a new body of Scriptures, which took its place alongside the old one, as its fulfillment, in the unfolding life of the church.
Beckwith's book may be the most compelling volume I have ever read.
