In “From Swiss Monk to Lakota Missionary: How Sitting Bull Transformed Bishop Martin Marty,” Paul G. Monson examines the relationship between the Lakota leader and the bishop. Before arriving in Dakota Territory, Marty’s religious training emphasized a communal approach to missionary work. After meeting Sitting Bull in 1877 and 1879, however, Marty reformed his method and stressed individualized self-determination in regard to conversion. Monson is an assistant professor of church history at Sacred Heart Seminary and School of Theology near Milwaukee, Wis.
