By combining textual analysis with an ethnographic study of the Jesuits Blackburn is able to reveal the gap between the domineering language of the Relations and the limited authority that the Jesuits were able to exercise over Native people, who actively challenged much of what the Jesuits tried to do and say. She highlights the struggle between the Jesuits and Natives over the meaning of Christianity. The Jesuits' attempted to convey their Christian message through Native languages and cultural idioms. Blackburn shows that this resulted in the displacement of much of the content of the message and demonstrates that the Native people's acts of resistance took up and transformed aspects of the Jesuits' teachings in ways that subverted their authority. Harvest of Souls is essential for all those interested in new approaches to historical and contemporary relations between Europeans and Native peoples in North America.
