Did god really condemn mankind? Is god a just god? This means that God is not a prick, nor is he genocidal because we can't take the claims of what he did literally. It is the story you must read, at least according to you, without regard to the literal translation. For that reason, if the Bible claims he killed all sorts of people, he literally did not, so you must decipher the meaning of the allegory. — Hanover
It is slightly more complicated than "all of the Bible is allegory".
One can observe very striking differences between scripture that is attributed to Saint Paul and those scriptures that have been identified as being older; those of Matthew and Luke. Matthew and Luke, containing the teachings of Jesus, bear far more resemblance to wisdom literature than religious scripture. They contain no miracles, no post-resurrection, etc.
The fact that Paul's writings differ so much from earlier writings means that it needs to be looked at most suspiciously, including all that it influenced. Ironically, most of what modern Christianity teaches is
Pauline in nature.
So what this could mean,
possibly, is that if one wants to understand the actual teachings of Jesus, most of the New Testament can be tossed in the garbage.
Furthermore, it is no secret that parts of Christianity have sought links with Judaism, especially Rome. This could explain the resemblance of the Christian God to the Judaic God. However, if the above may be true, these links are non-existent, and these resemblances are forgeries, later additions made with a different agenda than staying true to Christian teachings.
While I have read much on the topic, I realize I am no expert on this topic. So if you are interested I can provide some links to persons who do a much better job at explaining all of this.
