This is very strange - because I can't think of another single passage which so completely uproots the doctrine. There are dozens of others which do so by implication (such as Jesus saying Jn 20. 17 ... I ascend unto my Father, and your Father; and to my God, and your God) but this one is the plainest.It doesn't seem like you're understanding what I've said. My logic is very sound and 1 Cor 8:6, despite being continually used by anti-trinitarians, very much supports trinitarian doctrine. It simply cannot be otherwise.
It's a pity you won't enter the discussion about whether Jesus could have been tempted or not - because it is extremely important in many ways, not least in understanding his sacrificial death.
I said that you are abandoning logic because the swimming pool clearly existed before I could come out of it. Is that too illogical for you?
