"A Catholic priest once said in a sermon, 'the Bible is true, and some of it happened" Quoted by Marcus Borg in his book entitled The Heart of Christianity (2003).
The idea that N.T. belief involves intellectual assent to a group of propositions is fairly recent in the history of Christianity, coming in with the advent of the Enlightenment. The Enlightenment unfortunately divorced modern man from a consciousness of spirit, and condemned us to a purely material viewpoint.
That being true the Bible, the creeds, other Christian artifacts only have reality when perceived concerning material events. Such as:
"If Jonah didn't spend three days in the belly of the big fish, then there's no basis for my faith"; these were the words of a young theologue from Mississippi in the O.T. class at the New Orleans Baptist Theological Seminary. A class mate with a different viewpoint replied:
"Whether Jonah spent three days in the fish's belly-- I really don't know. But one thing I do know: I was blind and now I see", referring to his own awakening experience, which he compared to the statement of the blind man healed by Jesus, as recorded in John 9.
One student confessed that his faith depended upon intellectual assent to all the happenings reported in the Bible. The other had had an experience upon which his faith was founded.
Before the Enlightenment belief meant trust, faithfulness, commitment. These are non-material categories. Religionists since that time have tended to major on facts.
Borg referred to that as the Old Paradigm and emphasis on the spiritual meaning of the Bible as the Emerging Paradigm, which roughly describes what have been known as fundamentalists and progressives.
About 1960 I read an essay on American Christianity that predicted that conflict in the church would be much more on that basis than on any denominational differences.
