Messianic Jewish (MJ) Congregations in Israel
Messianic Judaism, and Hebraic Roots movements have been going on for several decades. For those who don't know, simply speaking, Messianic Judaism is more Jewish in its approach to the Gospel. The Hebraic Roots movement is more evangelical Christian.
One For Israel Ministry says that there are at least 300 MJ (Messianic Jewish) congregations in Israel (representing 30,000 or more people). Their number of people (actual or estimated) represents an average of 100 people per congregation.
A simple internet search yielded lists of more than 500 Messianic congregations in the United States.
There are small numbers of former Jewish adherents in the Church of Jesus Christ of Latter Day Saints (LDS). Those numbers are not available. However, in Israel, as of 2022, there are 4 LDS Branches (small congregations), totaling a little over 300 people. Likely many of those people are Americans studying or working in Israel.
A Wikipedia article says that according to a 2013 study from the Pew Research Center, about 1.6 million adult Jews identify as Christian, mostly Protestant. There is a potential for the Mormon / LDS people to attract Jewish people to their Churches, should the Mormon people prepare themselves to invite, welcome and teach Jewish people. This needs to be done by lay members (as a personal action, not by ecclesiastical calling) because of the legal hurdles that the Church of Jesus Christ of Latter-Day Saints has with Jewish officials. Because of this, the Church does not have formal outreach to Jewish officials other than occasional invites to special events. A Jewish person, however, may join the Church. The LDS Church just can't have formal missionary programs to bring Jewish people in.
What people of a Christian-Mormon background often don't realize is that the study of Hebrew religious vocabulary, Hebraic thought, and learning the Biblical Feasts, will greatly enhance understanding of the full Gospel and Heavenly Father's plan to fulfill all his promises to His children on earth. The Jews have teachings which will complement our own.
