Hundreds of Mormon missionaries assigned to serve in Brazil increasingly find themselves preaching not in Rio de Janeiro, São Paulo or Fortaleza, but instead in Philadelphia, Pocatello, Idaho, or even Provo. The LDS Church’s São Paulo Missionary Training Center, which can accommodate up to 700 trainees, currently houses only about 60, none of them U.S. citizens. And the Utah-based Church of Jesus Christ of Latter-day Saints has lowered the missionary age from 19 to 18 for male Brazilians to make up for the loss of full-time American missionaries.
