As a Messianic Jewish leader, I address this book as a challenge to both the foes and friends of our movement. Should Jewish rituals be continued if one converts to Christianity? The election of Israel is irrevocable, rabbinic Judaism is a movement employed by God to preserve the distinctive calling of the Jews, and Messianic Jews should honor the covenant obligations of Israel. Despite its title, this is not mainly a book about Messianic Judaism. Instead, it is a book about the ekklesia -- the community of those who believe in Yeshua the Messiah -- and its relationship to the Jewish people. - Author.
