I just want to add to what
@rosends already said.
Not only is there no basis in Jewish Scriptures for a "Gentile Messiah" who's separate from the Jewish one, Christians don't claim that their messiah is different than ours and many of their prophecies are based on Jewish Scriptures that were altered to fit their ideal. So nobody is making the claim that you are.
Also, there are plenty of Priests today - although the Messiah is not a descendant of the Priestly class, so this is not an issue.
Red Heifers are not a separate species of cows, they're regular cows with some sort of genetic mutation that makes them brownish red and they're born all the time. They're also not used to consecrate the land, but to remove impurity from contact with a dead person from a live person.
Non-Jews currently occupy the Temple Mount, but presumably after the advent of the Messiah, they'll be more agreeable to putting up a Temple.
Jesus fulfilled no less than 40 prophecies of the Messiah. For all intents and purposes, as much as he can be the Messiah without running into contradictory prophecy, he is the Messiah.
44 Prophecies of the Messiah Fulfilled in Jesus Christ
But not necessarily measuring up to their standards, because they didn't like what he said. Seeing the hardness of hearts of the Jewish leaders, he decided to prophecy against them. Several times in fact.
Matt 23:31-33 "Therefore you are witnesses against yourselves that you are sons of those who murdered the prophets. Fill up, then, the measure of your fathers' guilt. Serpents, brood of vipers! How can you escape the condemnation of hell?"
Matt 15:1-3 "Then the scribes and Pharisees who were from Jerusalem came to Jesus, saying, "Why do Your disciples transgress the tradition of the elders? For they do not wash their hands when they eat bread." He answered and said to them, "Why do you also transgress the commandment of God because of your tradition?"
Matt 23:1-5 "Then Jesus spoke to the multitudes and to His disciples, saying: "The scribes and the Pharisees sit in Moses' seat. Therefore whatever they tell you to observe, that observe and do, but do not do according to their works; for they say, and do not do. For they bind heavy burdens, hard to bear, and lay them on men's shoulders; but they themselves will not move them with one of their fingers. But all their works they do to be seen by men."
Mark 7:5-7 He answered and said to them, "Well did Isaiah prophesy of you hypocrites, as it is written: 'This people honors Me with their lips, But their heart is far from Me. And in vain they worship Me, Teaching as doctrines the commandments of men.'
Matt 23:25-26 Woe to you, scribes and Pharisees, hypocrites! For you cleanse the outside of the cup and dish, but inside they are full of extortion and self-indulgence. Blind Pharisee, first cleanse the inside of the cup and dish, that the outside of them may be clean also.
Matt 23:27-29 Woe to you, scribes and Pharisees, hypocrites! For you are like whitewashed tombs which indeed appear beautiful outwardly, but inside are full of dead men's bones and all uncleanness. Even so you also outwardly appear righteous to men, but inside you are full of hypocrisy and lawlessness.
You can tell from Jesus's words against the Canaanite woman, about how he came for the Jews, and it is "not right to take the children's bread, and feed it to the dogs." Yet her response clearly changed his view on who was deserving of his ministry. After this, he preached on the Good Samaritan, and generally seemed more about saving the Christians than reforming the Jews. The sinners among the Jews were another story, but he largely stopped trying with the Pharisees, Saducees, and scribes.
“Healthy people don’t need a doctor—sick people do. I have come to call not those who think they are righteous, but those who know they are sinners.”
There is no prophecy of a Gentile Messiah, this is true. But the Messiah decided the Jews weren't ready yet. So, while among the early Christians, they were mostly circumcised Jews to start with, we have Peter's vision, and afterwards, non-Jews are being converted.
Acts 10 - Peter's Vision and Unclean Animals — Freedom Hill Community
Why, Peter asked, was he suddenly being called to disregard massive amounts of Jewish law about mixing with the unclean? Well, if God is unchanging (Malachi 3:6), this means that the Jews continued to be saved under the Law and because they were chosen people. But he was calling Peter and the other disciples not to be Jews. To provide salvation for the Gentiles. As you know, Christians are not Jews. They are not the Chosen People, they do not keep kosher, and they do not care about mixing cotton/poly fabrics. They care about their salvation. Before this point, Gentiles
did not have a means of salvation. They weren't under the Jewish law, and essentially weren't born into it, so Yahweh had no means of reconciling them as his Creation. This Messiah was a Savior, just not for those who already have a mitzvah to follow. And you've decided that this one who came for them is no good. Why is it your business any longer?
Obscure Taoist parable
“There is a kind of bird similar to the phoenix, called Yuanchu. Have you heard of it? For its migration flight, the Yuanchu bird travels from the Southern Sea to the Northern Sea. When it is tired, it rests only on the firmiana tree. When it is hungry, it eats only tender bamboo shoots. When it is thirsty, it drinks only pure stream water.
One day, there was an owl who found the rotting carcass of a rat. It was about to feast on the carcass when it saw the Yuanchu bird flying overhead. Alarmed, the owl immediately took action to protect its meal. It held onto the dead rat and squawked with all its might, trying to scare away the intruder."
Despite only eating bamboo and drinking spring water, the owl was convinced it was somehow a threat to their dead rat.
And so, I ask you, when the Messiah comes, will you reject
this one also? Or allow them to be
your Messiah?
