Not long ago, the families of Fairfax Presbyterian Church spent thousands of dollars to fly their teens to Mexico for eight days of doing good. They helped build homes and refurbish churches as part of an army of more than 1 million mostly Christians who annually go on short-term international mission trips to work and evangelize in poverty-stricken lands.
Yet even as those trips have increased in popularity, they have come under increased scrutiny. A growing body of research questions the value of the trips abroad, which are supposed to bring hope and Christianity to the needy of the world, while offering American participants an opportunity to work in disadvantaged communities, develop relationships and charge up their faith.
