We maintain the validity of the grammatical-historical and the theological principles of exegesis for all Scripture interpretation. Recognizing the principles of progressive revelation, specifically between the Old Testament prophets and the New Testament witness of Jesus Christ (Heb. 1:1-2; Jn. 1:7-18), we accept the essential unity of both Testaments which allows the meaning of any part of Scripture – including the prophetic parts – to be ultimately determined by the totality of Scripture. This classical Protestant hermeneutic, known as the sola Scriptura principle, seems to be accepted as an axiom of faith by all conservative evangelical Christians.
