47. Realize that the doctrine of sola Scripture is itself not biblical but, ironically, is received and believed as a sacred (Protestant) church tradition.
As an evangelical, you grew up accepting as an obvious, sacred truth the doctrine of sola Scripture—the Bible alone and no other human tradition as authority. This was not a point of orthodoxy that needed active justification and defending. It was simply taken for granted as a self-evident truth that informed all other thinking.
Stop taking sola Scripture for granted. Start asking if it actually makes sense, even when taken on its own terms. If sola Scripture is correct, then, for starters, to be an internally coherent and foundational belief, it needs to be authoritatively established by Scripture and by Scripture alone. But it isn’t. As strange as this might sound, the Bible nowhere says that Scripture or the written word of God is the sole and sufficient authority for Christian faith and practice. It just doesn’t. You can spend the rest of your life looking for Bible verses that say that and you will never find them. If anything, you will find passages commending both the word of God and the tradition of faith. Then you start wondering how you never noticed that before.
