Yes, Virginia, there is a metanarrative in scripture

Underlying Gregory's trinitarian analysis is the firm conviction that isolated texts of Scripture should be read in light of the overarching biblical narrative; because the Holy Spirit has inspired all the biblical authors, it is perfectly legitimate to allow one text to shed light on another. Rather than producing a forced harmony, the comparison of texts acknowledges the Spirit's overriding authorship of the entire Bible. Because the New Testament Scriptures are in continuity with those of the Old Testament, Gregory feels free to interpret the Old in light of the New. To fail to do so is to practice a wooden literalism that fails to observe the Bible's deeper unity in the Spirit.—Christopher Hall, Reading Scripture with the Church Fathers, 76–77
