This work is the first to present detailed, first-person accounts of the Mormon missionary experience. Armed with little more than youthful vigor and firmly held religious convictions, twins Gary and Gordon Shepherd left their home in Salt Lake City in 1964 for two years as missionaries in Mexico. Mormon Passage is one result of that experience, a combination of diaries and field notes kept by the two during their mission and sociological analyses of their experiences. The brothers' goal is to help readers understand the consequences of the missionary experience for the vitality of Mormon religious life. "Seldom has excellent research been woven so tightly with personal experience. . . . Very well written, a compelling narrative and an absorbing analysis." -- Lavina Fielding Anderson, coeditor of Sisters in Spirit: Mormon Women in Historical and Cultural Perspective
