Aye--Church precedes and defines Canon.
There is this view that immediately after St. Paul died the church became heretical and corrupt. The result of this view is that the Scriptures are pitted against the Church. This explains one of the many reasons for the growth of so many heresies and cults that claim to be following Scripture alone. The Scriptures were written by the church, for the church, and in the church. The Bible is truly the Church’s book. Because it is the Church’s book, all the teachings of the Church must conform to it.
