Here is a link to an Adventist Review article on Jewish-Adventist congregations: The Jews of Adventism.
Every Sabbath a growing number of Seventh-day Adventist congregations are taking on a distinctive appearance: men wearing skullcaps and prayer shawls, alongside women, recite prayers in the Hebrew language of their forebears. In many places the Torah, a parchment scroll of the first five books of the Bible—authored by Moses—is read from the platform. A Jewish flavor permeates the proceedings, even the potluck suppers.
“The change I have seen is tremendous,” Elofer told Adventist World. “In the 1990s we had no Jewish Adventist congregations in the world; today we have about 40 of them, 25 just in the United States. Each of these congregations is doing a great job of witnessing to Jews that Jesus is the Messiah. Before starting this contextualized ministry, Jews were coming to the church, but they did not stay; after three to five years they left the church. Today our ministry is so great that Jews have found their place in the church and stay and remain Adventist.”
