Guide for the Christian Assembly - A Background Book of the Mass, Volume II: Septagesima Sunday through Wednesday in Holy Week, written by Thierry Maertens and Jean Frisque, is an in-depth guide and commentary on the liturgy of the Mass during the Lenten period, from Septagesima Sunday through Wednesday of Holy Week. It focuses on the readings and themes of the Mass for the Lenten liturgy, revised in accordance with the new lectionary. The aim is to provide a manual that examines the new liturgical form in depth and shows how the Word of God proclaimed in Sacred Scripture is complemented by His word elsewhere, such as in current events in the world and in Church history. In short, this volume serves as a comprehensive tool for understanding and deepening the meaning and application of the Lenten Mass readings in the daily lives of the faithful.
