I think it is a mistake to imagine that there is a coherent message in either the OT or Greek scriptures. The texts are eclectic and use folk tales, borrowed rituals and stories and most certainly borrowed ideas.
Christianity from its start was a cult competing with other messianic cults and based on the pagan temple worship and its ritualised hope for salvation. Clear evidence for this connection is seen in Christianity using the same functionaries of bishops, presbyters and deacons etc as did the pagans. (It was only after Rome dominated and enforced Christian belief in a fusion of Catholic dogma that the earlier paganism was strictly proscribed).
Christianity evolved from paganism. The nature of the NT texts reflect the nature of seeking converts and avoiding the 'wrong type' of cult teachings on penalty as Paul said, of being "mentally diseased", it was about a scramble for prime position in the cult marketplace.
The first century christ story was not the same as the fourth century Roman fusion christ story. Consequently at the root of the choice of texts which are included in the NT canon are those which satisfy the cultural longings of the disparate groups of would be believers. Hence 1Cor 10;1 was used so as to resonate with Jews and be meaningful to them-- but not only Jews, the text also had to appeal to followers of Mithra, the saviour Dionysus and Orphic cults amongst others. It had to fuse polytheism with monotheism and bring the mainspring beliefs of each religion into an accommodation of credible acceptance to all. It was never a perfect fusion it always bore ambiguities.
At this distance in time from the writings, we should be looking at the historicity and sociological basis for these beliefs. To believe them or attempt to put any of it into practice is surely madness.
