Which Church document(s) says Scripture and Tradition have “equal weight”?
Dei Verbum 9, emphasis added:
Hence there exists a close connection and communication between sacred tradition and Sacred Scripture. For both of them, flowing from the same divine wellspring, in a certain way merge into a unity and tend toward the same end. For Sacred Scripture is the word of God inasmuch as it is consigned to writing under the inspiration of the divine Spirit, while sacred tradition takes the word of God entrusted by Christ the Lord and the Holy Spirit to the Apostles, and hands it on to their successors in its full purity, so that led by the light of the Spirit of truth, they may in proclaiming it preserve this word of God faithfully, explain it, and make it more widely known. Consequently it is not from Sacred Scripture alone that the Church draws her certainty about everything which has been revealed. Therefore both sacred tradition and Sacred Scripture are to be accepted and venerated with the same sense of loyalty and reverence.(6)
I don’t know if there is anywhere explicitly that says “equal weight”, but the quote from Dei Verbum makes the proposition rather unambiguous.
Thanks all. Dei Verbum is no doubt a document that asserts this. The phrase “equal weight” I probably heard in a Father Corapi talk…he probably was citing Dei Verbum as I know he did a series on that.
