Hope you are well Tanner? Constructive critique here,
So to begin with the title of the article is one any learned Jewish will very likely laugh at. The concept of the Messiah is one nobody fully understands, Jews debated it for years and there are absolutely no guarantees on what he must and must not accomplish. There is also no consensus on HOW these prophecies are supposed to be fulfilled. I will write a fill article responding to this but for now short summary on some of your points.
Messiah must be a king:
Jesus is from the line of David through Joseph and Mary so even by virtue of the virgin birth, He is from David. Luke 3 is Mary's genealogy. You made a big deal about Jesus not ruling for a day but Jesus Himself said His kingdom is not of this world, hence on his cross they even wrote "King of the Jews". The Jews tried to make him a king in John 6 by force but He refused.
2. World peace
Well Jesus said He came to bring not peace but a sword. He cites the same Hebrew Bible, Micah 7:6. He expected people to lose their families and even be out to death because of Him. So the same Hebrew Bible that says Messiah brings peace is the same one that says He will cause division. Hence my original point that the Messiah concept is not and has never been something cut and dried.
3. Has to gather the Jews back to Israel
Small problem here, the Jews rejected the Messiah! And there are portions of the Hebrew Bible that says the Messiah will first be rejected and then be craved for before he returns. Hence Jesus laments in Matt 23:37-39 over Jerusalem (roughly paraphrased)
"..how often I wanted to gather your children together like a hen gathers her chicks but you are not willing..your house is left to you desolate and you will not see me again, until you say blessed is he that comes in the name of the Lord"
You say there is no idea of a Messiah suffering? Uhm, have you ever read Isaiah 53? And did you know the Jews believe(d) in two Messiahs? Messiah Ben Joseph who comes to fulfill all the prophecies of the Messiah suffering and then dies, and Messiah Ben David comes to raise him from the dead and then fulfill all the verses about the Messiah ruling as king.
Again, I will write a full article response to this and based on your reaction to an earlier critique, you strike me as a decent guy...but this is very very bad..there is a lot more nuance and depth on the Jewish understanding of the Messiah than you present here, your understanding of this is waaay too wooden in comparison.
I highly recommend three books to you on this,
"What the rabbonim say about Moshiach" by Douglas Pile , pdf can be gotten on the internet free
"The Messiah texts" by Raphael patai (very boring book but goes into detail about Jewish beliefs and legends about the Messiah) pdf also available for free on internet
"Ha Mashaich- the Messiah of Hebrew scriptures" by Arnold Fructhenbaum, a messianic Jewish rabbi who goes in depth as to how Jesus fulfills the messianic prophecies (Granted you can see his "Christian bias" in some of his more tenuous points but overall very good and informative book).
Keep exploring and God bless.
