Most christians have been taught to reverence the Bible. This has been especially true of Protestant christianity. The Reformation was built on the doctrine of sola scriptura (by scripture alone). And when conservative christianity felt threatened by evolution, liberal theology and modernist thinking in the 19th century, it developed a statement of “the fundamentals”, one of which was the inerrancy of scripture.
It was designed to preserve the essentials of evangelical faith from attack. It probably did that for a while. Yet I believe it has contributed to a distortion of the Bible and the message of Jesus.
