No, lack of words still signifies nothing. There is no passage in Scripture which says 'only Scripture is inspired of God' or 'only Scripture is useful for teaching, reproof, etc.' There is, however, a passage at the end of St. John's Gospel, which asserts its incompleteness.

Yes there is, it's in my tagline.

John 21: 25 And there are also many other things that Jesus did, which if they were written one by one, I suppose that even the world itself could not contain the books that would be written. Amen.

By the way, how do you read that and conclude the bible is not complete?

[The_Reader_David]

Very simple: Holy Tradition records something Christ did, which is not recorded in the Gospels, to wit, miraculously creating an image of his face by pressing a cloth to his face, and sending it to King Abgar of Edessa, who had faith that merely seeing the Savior would cure his leporsy.

Now 'sola scriptura' types will insist this never took place because it is not in the Bible, in plain contradiction to St. John's conclusion, which say Christ did many things not recorded there in (and so many that you can't claim he is referring only to what is recorded in the Synoptic Gospels, but omitted in John's, since that would not amount to enough books the world could not contain them.)

Either there are not enough deeds of Christ not recorded in the Scriptures so that (on the Holy Apostle and Evangelist John's estimate) the world could not contain the books recording them, and we have a false passage in Scripture, or the Scriptures are not complete, as is necessary for the 'sola scriptura' position.
