People are supposed to be conformed to Jesus Christ, not “the Bible”. Protestants assume that the Bible is the Christian Owner’s Manual, and that our job as Christians is to follow the directions therein. It isn’t.
How else does one know how to emulate Christ except by reading His teachings, and those who knew Him and could speak of him? Anything else is Gnosticism, and there is already too much of that among churchgoers today.
This is why it is so distressing that so many in the church, Catholic and Protestant alike, prefer the approval of the world to the approval of Christ.
People assume the Bible is the Christian owner’s manual, because it is. The writings of those who knew Christ and were taught by Christ are the only way of conforming to Christ’s teachings. How else is one to know? Rely on feelings or their own understandings, even if those directly contradict clear scripture?
