With the introduction of the new lectionary the Guide For The Christian Assembly has been completely revised. The purpose is twofold: to provide a manual which studies the new formularies in depth, and to indicate in the commentary how the Word of God proclaimed in scripture is complemented by his word elsewhere... the word, that is, which mysteriously informs actual happenings in the world and in the history of the Church. The commentaries are divided into two parts: a brief exegesis of the readings for each Mass of the liturgical year, and a doctrinal discussion of the themes found in the Sunday liturgy. It is the hope of the authors that these commentaries will not only be useful in the preparation and prayerful lives as Christians.
