FALSE ASSUMPTION # 1: The Bible was intended to be the last word on faith, piety, and worship.
a). Does the Scripture teach that it is "all sufficient?"
The most obvious assumption that underlies the doctrine of "Scripture alone" is that the Bible has within it all that is needed for everything that concerns the Christians life — all that would be needed for true faith, practice, piety, and worship. The Scripture that is most usually cited to support this notion is:
...from a child thou hast known the Holy Scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus. All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, thoroughly furnished unto all good works (II Timothy 3:15-17).
Those who would use this passage to advocate Sola Scriptura argue that this passage teaches the "all sufficiency" of Scripture — because, "If, indeed, the Holy Scriptures are able to make the pious man perfect... then, indeed to attain completeness and perfection, there is no need of tradition."1 But what can really be said based on this passage?
For starters, we should ask what Paul is talking about when he speaks of the Scriptures that Timothy has known since he was a child. We can be sure that Paul is not referring to the New Testament, because the New Testament had not yet been written when Timothy was a child — in fact it was not nearly finished when Paul wrote this epistle to Timothy, much less collected together into the canon of the New Testament as we now know it. Obviously here, and in most references to "the Scriptures" that we find in the New Testament, Paul is speaking of the Old Testament; so if this passage is going to be used to set the limits on inspired authority, not only will Tradition be excluded but this passage itself and the entire New Testament.
In the second place, if Paul meant to exclude tradition as not also being profitable, then we should wonder why Paul uses non-biblical oral tradition in this very same chapter. The names Jannes and Jambres are not found in the Old Testament, yet in II Timothy 3:8 Paul refers to them as opposing Moses. Paul is drawing upon the oral tradition that the names of the two most prominent Egyptian Magicians in the Exodus account (Ch. 7-8) were "Jannes" and "Jambres."2 And this is by no means the only time that a non-biblical source is used in the New Testament — the best known instance is in the Epistle of St. Jude, which quotes from the Book of Enoch (Jude 14,15 cf. Enoch 1:9).
When the Church officially canonized the books of Scripture, the primary purpose in establishing an authoritative list of books which were to be received as Sacred Scripture was to protect the Church from spurious books which claimed apostolic authorship but were in fact the work of heretics (e.g. the gospel of Thomas). Heretical groups could not base their teachings on Holy Tradition because their teachings originated from outside the Church, so the only way that they could claim any authoritative basis for their heresies was to twist the meaning of the Scriptures and to forge new books in the names of apostles or Old Testament saints. The Church defended itself against heretical teachings by appealing to the apostolic origins of Holy Tradition (proven by Apostolic Succession, i.e. the fact that the bishops and teachers of the Church can historically demonstrate their direct descendence from the Apostles), and by appealing to the universality of the Orthodox Faith (i.e. that the Orthodox faith is that same faith that Orthodox Christians have always accepted throughout its history and throughout the world). The Church defended itself against spurious and heretical books by establishing an authoritative list of sacred books that were received throughout the Church as being divinely inspired and of genuine Old Testament or apostolic origin.
By establishing the canonical list of Sacred Scripture the Church did not intend to imply that all of the Christian Faith and all information necessary for worship and good order in the Church was contained in them.3 One thing that is beyond serious dispute is that by the time the Church settled the Canon of Scripture it was in its faith and worship essentially indistinguishable from the Church of later periods — this is an historical certainty. As far as the structure of Church authority, it was Orthodox bishops together in various councils who settled the question of the Canon — and so it is to this day in the Orthodox Church when any question of doctrine or discipline has to be settled.
We were having such a nice conversation, then you downgraded me to a cut and pasted response?

[15] So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.
