It feels disingenuous to come to the conclusion that Christians take all / most of the bible "too literally" on the evidence that they believe Christ was literally resurrected in the physical form.

If you were unaware, belief that Christ died for our sins and was resurrected is taught as the prerequisite to salvation and entering Heaven upon death. Given this fact, I would expect 100% of Christians to believe this.

As an additional note, modern Christianity (except maybe Catholicism) brush a lot of the old testament under the rug, of which includes Ecclesiastes I believe? Some churches teach Matthew 5:17 as support for doing so. Catholicism seems to have a more nuanced take: https://www.catholic.com/magazine/online-edition/did-jesus-r...
