NikL, I am not nit picking when I say that perhaps you ought to re-think your question.
It contains an assumption that there is a message in the Bible and that there is a correct interpretation of this message.
Think laterally; ask why are the writings there in the first place, why were the texts retained. The wrong primary question to ask is; what do they mean.
As we know the Bible first began with the Roman Church in the fourth century from an anthology of texts suited to the unifying goals of the Roman Empire. By choosing texts which brought together all of the important pagan cults, it satisfied both the secular and religious aims as represented in the Roman functionary who was called Pontifex Maximus (literally, the great bridge maker i.e. between heaven and earth). He was also known as the Pontiff or Pope or Papa, these very names were borrowed from the leader of the Mithraic cult. From this same pre-Christian source we get the notion of a heavenly reward after life, the memorial supper and most of the NT eschatology ("last things").
Nearly all of the Bible texts are borrowed and blended from yet earlier literary borrowings, the originals never claimed to be inspired of God because they were mainly folk stories told and retold for entertainment and transmission of their respective tribal culture lore.
So why should the Bible have a message other than the Roman demand for an empire wide Catholic faith?
