An anthology compiling the diaries, letters, and spiritual documents of 17th-century Jesuit missionaries (often called Blackrobes) in North America. This book brings together writings from the historical collection The Jesuit Relations and various other sources. It examines the spiritual lives of early Jesuit missionaries in Canada (New France). It focuses on their profound motivations, physical suffering, and theological views on sacrifice and death. It presents firsthand accounts from monks who dedicated their lives to preaching to local indigenous peoples. The writings show how the missionaries interpreted the brutal suffering and torture they endured from a spiritual perspective, seeing it as a form of self-identification with the suffering of Jesus Christ (known as sequela Christi). The book argues that martyrdom for the Jesuits was not simply a tragic end, but rather a form of pastoral service and the complete sacrifice of one's life for the salvation of others. It features writings from Jesuit figures who were later canonized as North American Martyrs (such as Jean de Brébeuf, Isaac Jogues, and Noël Chabanel). This book reveals the missionaries' deep convictions and provides a deep understanding of how Ignatian spirituality (the teachings of Saint Ignatius of Loyola) guided their actions, prayers, and mentality amidst the formidable challenges of the new colony.
