Churches Retool Mission Trips

The curriculum, for example, warns missionaries to think about their attire in conservative countries and what kind of message they're sending when they bring expensive cameras and other electronics to poverty-stricken villages.

Despite the concerns with trips abroad, their popularity is soaring. Some groups go as far away as China, Thailand and Russia. From a few hundred in the 1960s, the trips have proliferated in recent years. A Princeton University study found that 1.6 million people took short-term mission trips -- an average of eight days -- in 2005. Estimates of the money spent on these trips is upward of $2.4 billion a year. Vacation destinations are especially popular: Recent research has found that the Bahamas receives one short-term missionary for every 15 residents.

At the same time, the number of long-term American missionaries, who go abroad from several years to a lifetime, has fallen, according to a Wheaton College study done last year.

The short-term mission trip is a "huge phenomenon that seems to be gaining in momentum rather than waning," said David Livermore, executive director of the Global Learning Center at Grand Rapids Theological Seminary, who studies the trend.

Participants care for orphans, hold Bible classes, evangelize, paint homes and churches, and help AIDS patients, among other tasks.

But research has found that the trips tend to have few long-term effects on the local people or on the mission travelers. Some projects take away work from local people, are unnecessary and sometimes dangerous.

"I really don't think that most people are trying to be ugly Americans," said Glenn Schwartz, executive director of World Mission Associates and author of "When Charity Destroys Dignity." "But they're misinformed and don't realize how their good intentions can go awry."

Mission groups also often bring their own experts and ignore local authorities on the ground.

In Monrovia, Liberia, three years ago, tragedy occurred when visitors built a school to their standards instead of Liberian standards. During the monsoon season, the building collapsed, killing two children, Livermore said.

Critics also question the expense involved in sending people long distances. Short-term missionaries pay $1,000 each, or far more, in plane fare and other expenses to get to remote destinations.

A 2006 study in Honduras found that short-term mission groups spent an average of $30,000 on their trips to build one home that a local group could construct for $2,000.

"To spend $30,000 to paint a church or build a house that costs $2,000 doesn't make a whole lot of sense," said Kurt Ver Beek, a professor of sociology at Calvin College who conducted the research.

A coalition that organizes mission trips has also set up standards that call for consultations with local organizations during planning, cultural training for participants and qualified leaders to be sent with the group.

"If [the trips] are only about ourselves, then we're doing nothing more than using another culture . . . to get some benefit at their expense," said the Rev. Roger Peterson, chairman of the Alliance for Excellence in Short-Term Mission, who helped set up the standards. "I don't care what verse of the Bible you read, it's wrong, it's wrong, it's wrong."
