I still have a problem with your phrasing of the matter. I would argue that it is actually the rejection of Holy Tradition that is at the root of this.
In fact, as an Orthodox Christian, the notion that the Scriptures are “the authoritative Word of God” is strange to me. The Word of God is Our Lord, God and Savior Jesus Christ, the Scriptures are the Church’s books that provide the primary testimony to Him, both prospectively in the prophecies and typology of the Old Testament (and the Apocalypse of St. John the Theologian) and retrospectively in the report of His conception, birth, earthly ministry, teachings, Passion, Saving Death, Glorious Resurrection, and Ascension into Heaven, and the history of the earliest days of the Church, including the sending of the Holy Spirit upon the Church in the New.
All writings, even (or perhaps especially) divinely inspired writings, need a hermeneutic tradition in which to be interpreted, and it is the final abandonment of any remnant of Holy Tradition as the basis for Scriptural hermeneutics by folks like Anglicans and Presbyterians that leads to this.
