de Brebeuf, Marguerite Bourgeoys, Marguerite d'Youville, and D'Arcy McGee promoted Christian faith and service. The stories told here are those of both saints and sinners who revealed their spirituality through their lives of prayer, understanding, and good works. As the title indicates, both their saintly and unsaintly acts are included in their stories. Scholarly colleagues such as William Ryan SJ, Archbishop Attila Mikloshazy SJ, and Professor Mark G. McGowan clarified issues in the text. The Jackman Foundation provided assistance for the publication costs. Let me express my appreciation to the members of Tellwell Publishers of Victoria for the finished volume. I am most grateful for the help received in preparing the manuscript.
