Why did the Christian messiah fail to fulfill the messianic prophecies?

The scriptures also contain my phone number if you know how to read them properly (and if you already have the information that you want to "extract"). But if you actually read the scriptures, not so much.

So he built a metaphor, not a temple.

And yet the Jews don't accept Jesus as "the Temple" - so you can't use their concept of the Temple to back up your claim. Which has nothing to do with Him being the Messiah.

Well, according to your quotes it was the epistle writers who were redefining the idea of Temple - and they were doing it after Jesus had already died and failed to fulfill the requirements to be the Messiah.Was Napoleon the Anti-Christ? Let's just redefine Anti-Christ to fit Napoleon.

Yes, and as you point out, that idea may go back as far as Daniel or farther. But it's a separate idea from the Messiah actually rebuilding a physical temple.

Would it be any clearer if I said you can MISuse any book? Who am I to determine that the owner's handbook for a 1965 Pontiac Parisienne was meant for the owners of 1965 Pontiac Paresiennes? A sane person. You can pretend it was meant for teaching Vietnamese cooking if you want but who's going to take you seriously? Exactly. You can draw a parallel between any two things if you jump through enough hoops. That's my point: You can draw parallels between Jesus and the Messiah by doing the appropriate gymnastics but that doesn't mean the prophets meant Jesus when they said Messiah.

So Jesus redefined the prophecies to point to Himself. Is that self-serving at all?

Your reasoning is circular: He was the Messiah, so he redefined what the Messiah was to suit Himself.

That's pretty much a separate issue from the Messiah. Jesus taught the Jews how to be better Jews. That doesn't make Him the Messiah.I tend to agree that Jesus' teachings are a better idea than a military conqueror. But Christians should concentrate on those teachings and let go of the idea of Messiah. He may have been better than the Messiah but he was no Messiah.

There's little point in a prophecy that's "fulfilled" in an unexpected way. I've predicted that Donald Trump will win the US Presidency; if he doesn't, I can always say it was a "moral" victory - but of course it will really mean that I was wrong.

Jesus' self-understanding is irrelevant. A prophecy that nobody can understand before the fact is worthless.

Or... the little boy donating his lunch prompted other people to share their lunches. There's no need to bring up any nonsense about vegetarianism.

What does it have to do with messianic prophecies?

What's the difference between what people think the prophecies mean and what people think God intended? If the people who wrote the Old Testament can't be relied on to convey God's intent, how can the people who wrote the New Testament be relied on to convey Jesus' history?

So tell us something. The "New Age of peace and no killing" has nothing to do with vegetarianism. It's only about killing people.
