Here are some key findings:
•The most-immigrant faiths are not Christian. Hindus, Jews (of various streams), Buddhists, and Muslims each have above average levels of immigrants.
•Orthodox Christians, many of which have ties to post-Soviet countries, are also a high-immigrant faith.
•Churches that have a large presence in Europe (and their former colonies) are more likely to have immigrants. This includes Catholics, but also Anglicans, Lutherans, and Reformed churches.
•There are also higher percentage of immigrants in home-grown faiths that have had strong, successful missionary movements, including Seventh-Day Adventists, Jehovah’s Witnesses, Mormons, and pentecostal churches.
•Who has low percentage of immigrants? Methodists and Baptists. This includes both historically white churches (United Methodists and Southern Baptists) and historically black churches (African Methodist Episcopal and National Baptists). Southern Baptist Association is America’s largest Protestant group, but only two to four percent of the SBC are immigrants.
The last three churches I attended were mostly immigrants, the last one Russians, Uzbeks, Slavic Orthodox, etc and now middle eastern Catholics.
When you begin with one member one immigrant makes a bigger impact on your rate than when you began with a million members.
