Que? I've never suggested that Paul thought Jesus wasn't divine. We have no direct record of what Peter believed one way or the other.
The post of mine you were responding to was rebutting an earlier poster who sought to contrast what Paul believed with what "the earliest Christians" believed, so I assumed you thought they were in disagreement too.
I've noted that the view that Jesus was divine was not universal in early Christianity. Those who did claim that he was divine were not drawing from a single early source with one tradition, but came up with a variety of different explanations. It's clear that they were not drawing from one early universal interpretation of divinity, but that different people were coming up with different reasons for it.
So? "Some people thought Jesus was divine in this way, others thought he was divine in that way" doesn't at all contradict "Everybody thought Jesus was divine", in fact it backs it up.
I disagree with Thomas being dated later than John, or at least the core of Thomas. It probably passed through several redactions, much as the canonical gospels have various accretions. Canonical John makes more sense as a response to Thomas, in addition to the aspersions it casts on different apostles (by the second century, all of the apostles were becoming revered figures, so it's difficult to see it being later than that).
On the contrary, the Gospel of Thomas seems to rely on the Syriac translations of the original Greek Gospels, and so must be later than them.
Plus, whilst the final form of the New Testament wasn't fixed until the fourth century, the acceptance of Matthew, Mark, Luke and John as the canonical Gospels was far earlier, by the early-to-mid second century at the latest. This was because, as the early Christian writers tell us, these four were regarded as being written by people who were closer to Jesus than the other accounts of his life were, and therefore as being more reliable. If the Gospel of Thomas really did predate the other Gospels, we'd expect it to have been included as well, based on the criteria used for accepting or rejecting Gospels.
