This volume is the first ever book-length treatment of the distinctive American Indian Catholic liturgies of the Northeastern Woodlands. It compares and contrasts the Indian Masses of different missions with each other and with the official Roman Missal. It also contains chapters on the calendar and hagiography of the missions; formulas for Baptism, Matrimony, and other sacraments; the Divine Office; characteristic sacramentals and devotions; and religious life. The first book of its kind, and a must for scholars of Native American Catholicism.
