A critical element of the faithful reading of Scripture is a due regard for its unity and coherence. The practice of comparing Scripture with Scripture guards against fragmentary readings which frequently misuse individual texts. Biblical theology – the study of the unfolding nature of God’s revelation in salvation history, which highlights the relationship of each part of the Bible to its centre in the person, words and work of Jesus Christ – is immensely valuable in this regard. It expresses the conviction that Scripture is its own interpreter, that one of the most important resources God has given us to understand any part of the bible is the whole Bible. Faithful Christian doctrine and ethics rely upon both an explicit appeal to biblical texts, and an understanding of how those texts fit within the message of the Bible as a whole. This is also the commitment which lies behind the statement in Article XX of the Thirty-nine Articles of Religion: ‘And yet is is not lawful for the Church to ordain any thing that is contrary to God’s Word written, neither may it so expound one place of Scripture, that it be repugnant to another’.Β – Being Faithful: The Shape of Historic Anglicanism Today, p 127
