Messianic Judaism erroneously claims to be a branch of Judaism and presents itself as a bridge between Judaism and Christianity. So how many of them are there? Let's find out.
Today, there are over 1,000 Hebrew-Christian missionary groups that spend over $300 million annually, targeting Jewish people for conversion. In recent years, these missionary groups have succeeded in converting 350,000 Jews worldwide.
In an Atlantic article, titled "Kosher Jesus: Messianic Jews in the Holy Land," Sarah Posner explains that "there are an estimated 175,000 to 250,000 Messianic Jews in the U.S. and 350,000 worldwide, according to various counts, they are a tiny minority in Israel -- just 10,000-20,000 people by some estimates -- but growing, according to both its proponents and critics."
However, in addition to the growth of the Messianic movement, the 2012 Pew study found additional startling trends. "About a third of Jews (32%) say they had a Christmas tree in their home last year, including 27% of Jews by religion and 51% of Jews of no religion. Erecting a Christmas tree is especially common among Jews who are married to non-Jews; 71% of this group says they put up a tree last year. Compared with younger Jews, those 65 and older are somewhat less likely to have had a Christmas tree last year. And relatively few Orthodox Jews, including just 1% of Ultra-Orthodox Jews, say there was a Christmas tree in their home last year. Attending non-Jewish religious services is an infrequent occurrence for U.S. Jews; just 15% say they do this at least a few times a year."
It is these trends that drives Jews for Judaism's work to inspire and keep Jews Jewish.
