This volume serves as a comprehensive liturgical resource designed to facilitate the participation of the laity in the Roman Catholic Sunday Mass. The text provides the official liturgical texts, scripture readings, and prayers required for the celebration of the Eucharist throughout the liturgical year. By incorporating the Grail Psalms, the work emphasizes a specific translation tradition intended for communal recitation and prayerful engagement within the ecclesiastical framework.

This text functions as a standard liturgical tool for practitioners and clergy requiring a reliable, portable reference for Sunday worship. Its utility is defined by its adherence to established liturgical norms and the inclusion of specific, authorized translations for communal prayer.
