According to the editors, scripture, tradition and reason are the three criteria by which the adequacy of all Christian teaching has to be tested. Not only in Anglicanism, which has always particularly stressed the ‘threefold cord,’ but in all the Christian churches the relationship and relative authority of scripture, tradition and reason are nowadays the subject of wide debate and disagreement. Has one of them a primary voice over the other two? Or a ‘veto’? How can their respective influences in the past be evaluated, and what should it be in this modern age? These essays on scripture, tradition and reason will speak to the heart of nearly every major issue confronting the life and thought of Christian churches today.
