Divine Authority and Biblical Inspiration

As testimony to the self-manifesting truth of God in the gospel, Scripture is authoritative because it indicates the sovereignty and perfection of God's self-communication. This indication is reliable, and therefore authoritative, because God acts in, with, and over the human authors, ordering their acts of communication in such a way that they are caused to bear fitting and effective testimony. In the theological tradition, this divine oversight is usually termed "inspiration." By this is meant God's superintending of the processes of creaturely text-production.
