In celebration of the 50th Anniversary of Vatican II's Dogmatic Constitution on Divine Revelation, I will be posting twice a month, on Mondays, a paragraph from this important document. There are a total of 26 paragraphs, so this will take us through to the Fall when we reach the anniversary of its promulgation by Pope Paul VI on November 18, 1965. I look forward to our discussion. May I suggest a helpful book by Fr. Ronald D. Witherup called The Word of God at Vatican II: Exploring Dei Verbum published by Liturgical Press.
10. Sacred tradition and Sacred Scripture form one sacred deposit of the word of God, committed to the Church. Holding fast to this deposit the entire holy people united with their shepherds remain always steadfast in the teaching of the Apostles, in the common life, in the breaking of the bread and in prayers (see Acts 2, 42, Greek text), so that holding to, practicing and professing the heritage of the faith, it becomes on the part of the bishops and faithful a single common effort.
But the task of authentically interpreting the word of God, whether written or handed on, has been entrusted exclusively to the living teaching office of the Church, whose authority is exercised in the name of Jesus Christ. This teaching office is not above the word of God, but serves it, teaching only what has been handed on, listening to it devoutly, guarding it scrupulously and explaining it faithfully in accord with a divine commission and with the help of the Holy Spirit, it draws from this one deposit of faith everything which it presents for belief as divinely revealed.
It is clear, therefore, that sacred tradition, Sacred Scripture and the teaching authority of the Church, in accord with God's most wise design, are so linked and joined together that one cannot stand without the others, and that all together and each in its own way under the action of the one Holy Spirit contribute effectively to the salvation of souls.
