What is your authority? A historical parallel to the Protestant - Catholic/Orthodox divide

I love the way teaching my two Bible studies each week sometimes causes new ideas or connections to pop into my head in the middle of trying to explain a particular text of Scripture.  That phenomenon happened today allowing me to see for the first time what I think is a useful analogy for understanding the divide between Protestants and Catholic/Orthodox Christians over the issue of authority.

In the first century, Jesus confronted two of the groups of religious leaders within Judaism who had radically different approaches to the way in which they defined authority: The Sadducees and the Pharisees.  The Sadducees believed in the authority of the written text of Scripture alone (minus any oral tradition) and preferred to focus upon the Pentateuch (the five books of Moses) within the Tanakh (the 24 books of the Hebrew Scriptures).  The Pharisees, by contrast, accepted the authority of the Tanakh and also that of the Talmud and Midrash (the many generations worth of rabbinic commentary upon, and interpretation of, the Tanakh).

Is the parallel obvious yet?  Protestantism was founded upon the principle of Sola Scriptura (along with Sola Fide and Sola Gratia, "Faith alone" and "Grace alone"), that is the idea that Christian theology must rest solely upon the Scriptures themselves.  The Catholic and Orthodox traditions accept the authority of Scripture, but in conjunction with the teachings developed over time by the Church (through the various councils, synods, etc.)

Is it any wonder that Protestants and Catholics/Orthodox Christians have a hard time finding agreement upon a host of issues?  If the authority to which we must appeal is not the same, how can the answers derived from it be consistent?

That we have a different viewpoint of authority is no new observation, Martin Luther himself realized five hundred years ago that he was rejecting the authority of the Church in favor of that of Scripture alone.  I'm sure somebody has previously noticed the parallel between the Sadducees/Protestants and Pharisees/Catholic/Orthodox in the realm of authority, but the connection was new to my brain today, so I thought I'd share it.

Just as a reminder, Jesus had plenty of criticism for both the Sadducees and the Pharisees, something to keep in mind when we're tempted to climb up onto a high horse.  Both groups appealed to a different authority, and both were wrong in their conclusions/attitudes, both were in need of reform to reclaim the heart which God requires of his people.
