According to the Central Conference of American Rabbis (Reform):
"For us in the Jewish community, anyone who claims that Jesus is their savior is no longer a Jew and is an apostate. Through that belief she has placed herself outside the Jewish community. Whether she cares to define herself as a Christian or as a 'fulfilled Jew,' 'Messianic Jew,' or any other designation is irrelevant; to us, she is clearly a Christian."[74]

Concerning Christian-Jewish reconciliation and Christian missions to the Jews, Emil Fackenheim wrote:
"…Except in relations with Christians, the Christ of Christianity is not a Jewish issue. There simply can be no dialogue worthy of the name unless Christians accept — nay, treasure — the fact that Jews through the two millennia of Christianity have had an agenda of their own. There can be no Jewish-Christian dialogue worthy of the name unless one Christian activity is abandoned, missions to the Jews. It must be abandoned, moreover, not as a temporary strategy but in principle, as a bimillennial theological mistake. The cost of that mistake in Christian love and Jewish blood one hesitates to contemplate. …A post-Holocaust Jew can still view Christian attempts to convert Jews as sincere and well intended. But even as such they are no longer acceptable: They have become attempts to do in one way what Hitler did in another."[75]

According to a 1998 Audit of Antisemitic Incidents issued by Canadian B'nai Brith,
"One of the more alarming trends in antisemitic activity in Canada in 1998 was the growing number of incidents involving messianic organizations posing as "synagogues". These missionizing organizations are in fact evangelical Christian proselytizing groups, whose purpose is specifically to target members of the Jewish community for conversion. They fraudulently represent themselves as Jews, and these so-called synagogues are elaborately disguised Christian churches."[76]

Israeli Citizenship
The state of Israel grants Aliyah (right of return) and citizenship to Jews, and to those with Jewish parents or grandparents who are not considered Jews according to halacha, e.g. people who have a Jewish father but a non-Jewish mother. Specifically excluded were any “person who has been a Jew and has voluntarily changed his religion.” An Israeli Supreme Court decision in 1989 ruled that Messianic Judaism constituted another religion.[80] The Israeli government therefore rejected as a matter of course applications from Messianic Jews under the Law of Return.
On April 16, 2008, the Supreme Court of Israel ruled in a case brought by a number of Messianic Jews with Jewish fathers and grandfathers. Their applications for Aliyah had been rejected on the grounds that they were Messianic Jews. The argument was made by the applicants that they had never been Jews according to halacha, and were not therefore excluded by the conversion clause. This argument was upheld in the ruling.[72][81][82]
