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

There you go making stuff up again. Faith, many of us have actually read the Bible. There is nothing in the Pentecost story about Jesus being a King nor did they go out and preach that Jesus was a king. There you go making really silly claims Faith; claims that are refuted by your own words. If it ain't happened yet then it is still failed prophecy.It really is that simple Faith no matter how often you pretend it is otherwise.

Only when viewed through eyes that are biased to Western Greek & Roman mythology. Virgo the constellation is as much a myth as Virgo the Goddess just as Revelation is only an apocryphal fable about what was expected to happen and did not happen over a thousand years ago.Jesus failed to fulfill the Jewish Messianic prophecies because Jesus is not and never will be the Jewish Messiah.Just as Jesus was never a Christian.It really is that simple.

While there may be millions upon millions of people who believe that is true there is not even one that actually knows it is true and all of the evidence is that it is certainly not true.The only part of that statement of your that is true is that it is likely the author of Revelation was a real person.
