"In November 2011, I met an American missionary who has served in Guatemala for 36 years. He described a recent (unpublished) doctoral study examining Protestantism in one part of Guatemala. The Hispanic scholar had hoped to substantiate Max Weber’s thesis on the connection between Protestantism and economic development. The data, however, drove him to conclude that the gospel taught by present-day American missions makes no perceptible difference to the economic life of the believing communities."
