This phrase refers to a specific edition of a Roman Catholic prayer book authored or compiled by Father Francis Xavier Lasance. These prayer books, typically bound in small, portable formats, contain a collection of prayers, devotions, and liturgical texts designed for personal use. An individual’s personal copy would naturally be referred to as “my prayer book.” Father Lasance’s name serves as a crucial identifier, distinguishing his compilations from numerous other prayer books available at the time.
The importance of these prayer books lies in their accessibility and comprehensive nature. They offered a structured approach to prayer and fostered personal piety among Catholics. They provided a readily available source of liturgical texts and traditional devotions, promoting consistent spiritual practice. Historically, these books played a significant role in reinforcing Catholic identity and practice, particularly during periods of social change and modernization. These books also assisted with the standardization of prayer by including the order of important masses.
