That which determines your authority is your authority.
Scripture cannot determine its form since it does not list a canon (or even criteria for one).
The Church can, though.
Therefore, the Church is penultimate authority (1, 3).
That which determines your authority determines how the sub-authority (or text) is to be read (1, 4).
The Church determines how Scripture is to be interpreted (3, 5).
Jude 3 says contend for the faith once delivered to all the saints.
This delivery was made independent of a complete canon (which blocks Bahnsen’s contention that recognition of a canon is distinct from its authority. I don’t grant that, but let’s pretend for a moment: so what? The apostolic deposit was made either before the canon was complete or before Jude knew of the “canon” (and I still maintain that the idea of a New Testament canon probably wasn’t known to the apostles). Further, this “deposit” is somewhat synonymous with “tradition.”)
Therefore, “scripture” and “tradition” are not the same (8).
Yet, there exists cases where “tradition” is used in a positive sense (2 Tim. 1:13-14; 2:15).
