Perhaps it would be easier to think of Church governance like civil governance. Trying to maintain the Church using nothing but the Bible would be analogous to running the country using a Constitution, but doing so without any judicial mechanism.
And before one is tempted to note that Jesus is the head of the Church, let us recall it is beyond dispute there are many issues on which our Lord simply as decided not to give any clear direction.

Will Scripture be made subject to tradition?
