Dear Brother. Shalom.
The Messiah is a Jew. Everything about Him is Jewish. To have faith in Jesus (Yeshua) can never be anything but a Jewish faith in God of Abraham, Isaac and Jacob.
The problem is that many false followers if the Messiah have robed Yeshua from His Jewishness. The Messiah joined the celebration of all Jewish festivals. Many false Christians have no clue what Jewish festivals are all about.
I fully understand that many Jews are not able to see that “False Christianity” is not the true faith in the Messiah. They can be seen as strongly opposing the Jews right to a homeland. Both the secular and religious among your brethren have a right to live in Israel, with today’s borders.
But the Messianic Jews are not like that. The large majority of them are strong Zionists, send their children to the IDF, and celebrate all Jewish holidays. You can not say the same about many groups of Ultra Orthodox Jews. Some of them work for the destruction of the state of Israel.
Hope this was the same Ivar you have come to know, and love.
