Here are some of my favorite quotes on the role of Scripture in Catholic Theology. . . some of them might surprise you!
Vatican II, Dei Verbum 11: “The Sacred Scriptures contain the Word of God, and, because they are inspired, they are truly the Word of God. Therefore, the ‘study of the sacred page’ should be the very soul of theology.”
Thomas Aquinas: “Only the canonical scriptures are the standard of faith.”
Joseph Cardinal Ratzinger: “Dogma is by definition nothing other than an interpretation of Scripture.”
Joseph Cardinal Ratzinger: “The normative theologians are the authors of Scripture.”
Pope Leo XIII: “Most desirable is it, and most essential, that the whole teaching of theology should be pervaded and animated by the use of the divine Word of God.”
The Sacred Congregation for Catholic Education, The Theological Formation of Future Priests : “The basic fact which theological teaching must take into account is that Sacred Scripture is the starting point, the permanent foundation, and the life-giving and animating principle of all theology.” The document goes on to say, “The teaching of Sacred Scripture must culminate in a biblical theology which gives a unified vision of the Christian mystery.”
John Paul II citing Paul VI: “Sacred Scripture is ‘a perpetual source of spiritual life, the chief instrument for handing down Christine doctrine, and the center of all theological study.’”
John Paul II, lecture to the Faculty at the University of Lyon: “Theology must take its point of departure from a continual and updated return to the Scriptures read in the Church.”
Pope Benedict XVI: “We are grateful to God that in recent times, and thanks to the impact made by the Dogmatic Constitution Dei Verbum, the fundamental importance of the Word of God has been deeply re-evaluated. From this has derived a renewal of the Church's life, especially in her preaching, catechesis, theology and spirituality, and even in the ecumenical process.”
