Yes, that fits what I’ve heard about Messianic Judaism. It seems to be an Evangelical Protestant sect that uses underhanded tactics to trick Jews, as if Jews are some kind of secret prize and you win points for the most conversions.
The Catholic Church of course desires the coming in of all Jews, as it does all people, but we’re not going to pretend like we’re just like the Jews. We are FROM the Jews, from Judaism, but the Kingdom of the Messiah is necessarily different from the preparation for the Messiah. The Catholic Church would be the next logical step of growth for Judaism, just like the teachings of Moses were the next logical step from the Covenant of Abraham. Just like those Jews post-Egypt, we honor and love our heritage and consider it continuous, even though we do things somewhat differently now than we did before the Messiah came. After all, the Jews of Moses’ time didn’t even have the Ten Commandments, or the Torah. Can you imagine?! Similarily, we say the Jews of the Second Temple period “didn’t even have the Gospels”. For us it’s a similar step.
As for why things like the Kosher laws were dropped, I personally think it has a lot to do with the reason those laws were in place to begin with. It’s my understanding that the Jews don’t necessarily believe that eating pork is inherently evil, it’s just something that they’re not supposed to do. God said so, and the Jews rightly don’t argue with God. Why would God say something without giving any reason? Well, I think He did give a reason: do not do as the Gentiles do. He didn’t say this because the Gentiles’ diets were evil per se, but because the Hebrews absolutely needed to remain seperate and distinct. How could they be a “light unto the Gentiles” if you couldn’t tell a Jew from an Caananite? God literally built the Jewish people from the ground up, building into their culture the kind of uniqueness and obedience that would be absolutely pivotal in the Messianic promise. God needed to make a foundation of rock to build the Kingdom of the Messiah on, and that rock needed to be very clear and obvious, not to mention rock-solid even about the most seemingly trivial things.
It is by virtue of this loyalty and this self-enforcing distinction based on God’s commands that the Messiah was brought to the world. The Messiah had to come from a distinct, holy people, a dedicated people, a people who had a strong sense of duty and identity. God literally made the Jews that way, and that’s an honor Gentiles can’t even imagine. The whole Tanakh is about God sculpting the Jews and making them known to the world, and Catholics believe that this was so that when the Messiah came he would not be a shot in the darkness, but a light shining from a mountain that all humans could recognize.
From the Church’s perspective, once the Messiah had come, and the Covenant was universalized, these aspects of Judaism became spiritually superfluous, though not necessarily culturally superfluous. Their greater purpose of sculpting the Jews as a loyal and unique people had been fulfilled, and so they were relaxed for those who could no longer bear the burden. Jews were certainly still allowed to keep things for their cultural value, however, as were the Gentiles. It only became a problem when some Jews insisted that these things still held spiritual weight, and were therefore obligatory for all Christians, and this is what Peter and Paul rallied against.
Not in any way does he fit the description of the Jewish Messiah, which is plainly clear. Yes, there are Jews all over the world. That’s common knowledge.
