Below is the whole thing..skip down to the ===> if you arrived here from that question since you've read everything else up to it.
Imagine a scenario were a group of people decided that they wanted to be known as U.S citizens but couldn’t qualify because they fit none of the criteria of laws of citizenship and they believed the laws of the United States were too difficult to follow and didn’t like them so they have to be wrong. They claim they have texts that “fulfill” the Constitution and Bill of Rights of the United States but upon direct comparison, those texts are complete rewrites, contradicting the Constitution and Bill of Rights on every major point of law, and then they insist that the original and actual criteria for citizenship that is written into the laws of the United States shouldn’t apply and those who claim that the laws of the United States are **still all valid** and only the United States and its laws get to determine who is or isn’t a citizen are all hateful bigots who deserve eternal torture.
Do you think they have a right to arbitrarily declare to all the citizens of the United States that THEY have the entitlement to negate all the laws and citizenship criteria of the United States because they decided to make their leader into their god to appeal to authority to say their god decided that none of the citizens of the United States are citizens any longer and that they are all the real citizens of the United States? Do they have a right to be known as United States citizens and speak for all U.S. citizens?
And more importantly, when United States citizens declare to those people that they do not have a right to hijack the identity of United States citizens to lie about insult everything about the United States and its laws and people, should the world remain silent to it or even monetarily and verbally support it as the RIGHT of those who hijacked the laws and also insist that the real U.S. citizens embrace them as citizens too even though their efforts are to remove the Constitution and Bill of Rights and replace them with laws that are contradictory to them???
In the case of the Christians claiming to be Jews, they redefine the nature of God to one antithetical to the Creator that all Israel experienced in Divine revelation and who Jews believe was being honest when communicating that God does not become a man, nor do men become gods. Jewish laws and customs in the Tanakh were created specifically to separate them from those who worshipped their rulers as gods incarnate and worshipped other false gods .Religion and rule were inseparable in the ancient world. Jews were originally ruled by judges, who used God's law of Torah, then the Jews demanded/insisted to have kings like others and God let them ..only to show the harsh lessons of what happens when rulers are given too much power over others rights..and wicked kings abounded with the resulting punishments to Israel for straying, time and again. Yet there were always at least a core remnant of people who upheld Torah and preserved it intact to today. God can do anything God wills. But would God do something he said he wouldn’t do and had as a part of an eternal contract? If you want to believe that God is a God of justice, mercy and truth..you would be insisting that God deceived the eternal covenant nation for more than 3500 years if you claim God is a man. Jews believe God who obligates us to tell the truth would not lie to us.
That is precisely the form of disrespect that the New Testament adherents who call themselves “Messianic Jews” supported by different churches are doing. While most who use that name deceptively aren't Jews, Jews who convert to Christianity are not following Judaism . According to God’s laws in the Torah (Exodus is clear on this ) they have willingly left the Jewish people and they are separated of their OWN choice.
Just as the laws of the United States define who is or isn’t a citizen, the laws of the Jewish people alone have the ability to determine who is or isn’t a member of the Jewish people. Just calling yourself an American doesn’t make it so, and calling yourself a Jew even if you don’t qualify doesn’t make you one. Their religion is not forced upon them. It wasn’t forced upon them to leave their people. That a Jew who adopts a different/contradictory religion is no longer of the Jewish people is not popular opinion but eternal law. According to Jewish law, a Jew has to choose to leave the eternal covenant through following worship forbidden by God in the Torah (avodah zara) and they lose all rights, obligations and recognition as a member of the Jewish people. They are only considered a Jew for the purpose of judgment of their apostasy and violation of one of the three cardinal sins that a Jew should not commit even if faced with death. Worship of a man as God incarnate is idolatrous and blasphemous worship according to the laws of Torah. Such an apostate may only be counted among Yisrael if they repent of the foreign false god worship through formal declaration and then return to Judaism. Otherwise, they remain outside of the Jewish people and that is not disrespecting their right to choose to be a part of the Christian people, it is respecting God’s commandments for Israel and the right of the Jewish people to maintain our own laws we believe God gave us at Sinai and Jews believe are eternal.
The New Testament depicts a redefined notion of messiah to be an incarnate manifestation of God. This is antithetical to the eternal covenant at its most basic core element the affirmation of faith and the recognition of God’s eternal nature revealed to ALL Israel directly at Sinai. Believing Jews believe that God did not and does not lie about His very nature to all Israel whom He has preserved as an eternal covenant nation dedicated to exclusive worship of the incorporeal Creator. The covenant remains intact for the Jews as a people in obligation as a light unto the nations in how to strive to honor God’s gift of life and strive to work with God and our fellow humans all equal before our Creator..to make the world better for ourselves and for the lives to follow ours.
See http://www.whatjewsbelieve.org and the new book from Rabbi Stuart Federow ( Judaism and Christianity; a Contrast available online and highly recommended) that uses Biblical explanations to show you how very different the two religions are from one another and the irreconcilable differences that cannot be overcome. For one born a “citizen” of the Jewish people, either God is ONE and does not become a man, or you choose to believe God lied to Israel and you are not a part of the Jewish covenant. There is no way you can impose Jesus worship into Judaism or upon Jewish observance without utterly violating the core of the eternal covenant between God and Israel.
Unfortunately, because too many Christians think that Judaism is like Christianity without Jesus,and are clueless as to the actual nature of Judaism from the *context* of TANAKH , but have only a perspective of what their New Testament redefines about it, don’t see how antithetical the two religions are, nor how disrespectful it is for one group to hijack the identity of another to claim to negate the other's path as invalid and to replace them.
To understand what it is that Jews are awaiting, or more accurately..PREPARING in how we live our lives, in belief of God's messianic promise for the world, I respectfully suggest that you read the following:
http://thejewishhome.org/counter/Wanted.pdf This is a list of the criteria that God established for Israel to know regarding the Davidic Messiah. The world is objective evidence we are not in a post messianic age. The Christian religion's redefinition of messiah fits Jesus and is meaningless to Judaism and antithetical to what Jews await, and so is their notion of their antichrist that they believe Jews will worship. Believing Jews will never worship ANY human as a god incarnate. Ever. Period.
