Is the canon merely an anthology of the religious literature of the day, making it no longer possible to speak of its unity? This article indicates two main ways in which the issue of biblical unity is typically presented: unity may be based in the process of divine inspiration which is believed to have brought about these writings, or it may be based in a theory of providential ordering. Watson shows how both approaches fail to reflect on the relation between Scripture and gospel. The proclamation of what God has done in and through Jesus and his Spirit must be the governing principle. The example of the letter to the Galatians, where Paul struggles to articulate an evangelical hermeneutic for scriptural interpretation, is reflected upon. Paul's hermeneutic is not imposed on the texts from the outside, but it identifies fundamental elements in the dynamics of the biblical texts he uses. Watson believes Paul’s argument can serve as a model for our own attempts to rethink scriptural unity.
