1. I am starting to think that a doctrine of Scripture should be a subset of ecclesiology rather than as a stand alone topic of bibliology. To many this will probably sound like a step towards Catholicism, I hope it is rather a step towards the ancient churches of Rome, Antioch, Jerusalem, and Alexandria. I should note that my colleague at HTC, Prof. Andrew McGowan in his book The Divine Spiration of Scripture, has recently argued that a doctrine of Scripture should be placed in the context of the Doctrine of God!
2. The idea of situating one's beliefs in the context of the great tradition of the church is an idea explored by Steve Harmon in his excellent book Towards Baptist Catholicity.
3. On the Rule of Faith, Peter Balla in his book Challenges to New Testament Theology, has argued that something similar to the Rule of Faith is in fact the centre of a NT Theology. In which case the Rule of Faith is created by Scripture, the upshot is that Scripture itself creates the framework in which it is to be interpreted.
