1. The post-Easter emergence of a common culture of worship, mission, and reflection — not isolated ecclesial communities (“Markan,” “Johannine,” “Pauline”), but rather an integrated field of reflection and argument.
2. The textual interrelation of the NT texts: Synoptics to John to Johannine epistles; Luke to Acts to Paul’s letters; Paul’s letters to Hebrews; Paul’s letters to James to 1 Peter to 2 Peter to Jude; Paul’s letters to Apocalypse (?)
3. The common culture of textualizing theological discourse in terms of the OT.
4. The antecedent probability, from a Christian standpoint, that a “hermeneutic of continuity” will offer the most fruitful approach to narrating the movement from Jesus’ ministry, to the earliest Christianity, to the clear emergence of the Catholic Church in the second century.
Taking seriously these principles would yield a very different approach to NT Theology than the one commended by Troeltsch, and taken up by Bultmann, Kummel, and Schnelle. Its theological underpinnings would broadly come from Newman, and it could draw fruitfully on Bauckham’s and Burridge’s work on the gospels, on Martyn’s and Campbell’s work on Paul, and on much else besides.
