This is how I view it: the revelation of God to the world is firstly the actual, historical life, death, resurrection, and Ascension of Jesus Christ, the Only Begotten Son of the Living God. In this perspective, Scripture is still revelation too, but firstly Scripture is a written witness to God’s revelation by members of the early Church, and it is from here we can then talk about how it also part of the revelation.
Tradition, then, should be understood as another witness that also arises from the same source as the Scripture: the actual, historical life of Christ to his Apostles.
Under this understanding, it makes little sense to talk about Scripture being “more true,” because both it and tradition* are methods that this revelation is transmitted to us that also partake in the revelation as well. The eyes see and the hands touch the same thing, they are different ways of knowing the same thing. The key here is to understand that they are different ways of knowing some thing (methods) that arise from the same source (the historical expression of God).
Instead of thinking of the story of the Crucifixion as the revelation firstly, think of the historical event of the Crucifixion as the revelation, and the story as that by which we know the Crucifixion. The Apostles, after all, didn’t need the New Testament to know about the revelation of the Christ.
Sola Scriptura is part of modern thinkers general errors in epistemology, in particular the error of trying to reduce our knowing of truth to only one method. Sola Scriptura and scientism, for example, are the same erroneous spirit in different fields of knowledge. At least Sola Scriptura isn’t an obvious contradiction (although it has no basis)!
Now, with all this said, we might be able to talk about Scripture being superior to tradition insofar as Scripture being the Word of God, that is, that every word the Prophets wrote being agreed to by God. But even this approach might be problematic.
Christi pax.
*Tradition is a tricky thing to understand. Part of tradition involves the historical witness of the Church Fathers (via Trent), part of tradition involves reflection on revelation as mediated by the Church’s Apostolic teaching authority (via Newman), and part of tradition involves things that are part of the revelation, yet are in principle not things we can write down, like the Mass (do this in memory of me, not read this in memory of me) or the lives of the saints (models of the Gospel, proper images of Christ himself) (via Benedict XVI).
