Ready-made community may be one reason why immigrants figure prominently in many evangelical congregations. Those with established religious ties in their countries of origin tend to build their own churches. According to Boston's Emmanuel Gospel Center, recent counts, for instance, showed some 400 evangelical Brazilian churches in Massachusetts and southern New Hampshire, along with 15 Cambodian ones. Immigrants have also been drawn into existing churches: St. Matthew Trinity Lutheran Church in Pawtucket, Rhode Island, has reached out to the thousands of Liberians who live in the Ocean State, for example, and Faith has a sizable first-generation Latino population.
