Peter Cohen, himself a Messianic Jew gives a very balanced perspective (based on the scriptures) that the difference between the Church and the Synagogue, Christianity and Judaism is at its core, a theological divide, not a racial divide. He takes some excerpts from Jacob Jocz's book, "The Jewish People and Jesus Christ, The Relationship Between Church and Synagogue."
Excerpt:
Jesus remains a rock of offense to Judaism. The line that divides Jews and Christians is not a racial divide but a divide that exists in our attitude to Jesus Christ. This divide is only bridged by a change in our attitude to Him. Jocz sums this up as follows:

Jacob Jocz (a Messianic Jew) lived from 1906-1983. He was born in Lithuania and studied in Warsaw (Poland), Frankfurt-am-main (Germany) and Birkenhead (England). In England he served as head of the London mission to the Jews from 1939-1948. In 1957 he went to Canada and in 1960 he was appointed as professor of theology at Wycliffe College in Toronto.
Messianic Good News was founded in 1950 for the purpose of proclaiming the good news of salvation in Jesus the Messiah to Jews and Gentiles primarily through the written format. They publish and distribute tracts and books for outreach as well as the quarterly, "Messianic Good News,” through which we aim to encourage and equip readers with a deeper understanding of the faith. The ministry originated in Hamburg, Germany in the late 1800’s with the conversion of a young Jew named Arnold Frank. Frank had a burden to share the good news of salvation with the many Jewish emigrants who were passing through Germany hoping to find a better life in the new world. He published and distributed gospel literature and he also responded to their dire physical needs by organising a soup kitchen, a hospital staffed with compassionate Christian nurses and the Mission House, "Jerusalem” to accommodate and disciple the many young Jewish enquirers who were responding to the gospel.
In 1938, at the age of 79 he was forced to flee to Ireland to escape arrest by the Nazis. The mission property was confiscated but Frank continued to minister in Ireland for a further 26 years until his death at the age of 106. Although the Nazis tried to destroy the work he had dedicated his life to, his legacy lives on through the labours of those whom he led to the Saviour.
One of those young men was John Düring, who fled to South Africa in 1938. In 1950, Düring, with Frank’s support and blessing, established the "Good News Missionary Society” primarily as a literary outreach to Jewish people. Düring established a strong witness to the Jewish people through the excellent literature produced by the society. In 2000 the society was renamed "Messianic Good News” and continues to publish and distribute literature proclaiming the good news about the Messiah. They have an office in Johannesburg, South Africa, as well as in America and their literature is also translated into Spanish and German.
