Anyone who sets himself up as an authority (of sorts!) on the Bible should preface his teachings with a statement of what his own basic authority is for interpreting it. On the magic web I happily came upon a noted authority who expresses my own belief so cogently that I feel led to reproduce it here as an example of how I think about the Bible:
""I ground my understanding of the Bible in the Confessions of the Reformed tradition. A line in the Scots Confession of 1560 states clearly my approach to reading scripture: "We dare not receive or admit any interpretation which is contrary to any principal point of our faith, or to any other plain text of Scripture, or to the rule of love." We begin with the plain text of scripture, then interpret a text within the context of the whole Bible and the teachings of the church, and finally test our understanding by the great commandment to love God and our neighbor."
These are the words of Robert Traer.
