Comment: Catholic liturgy calls for the involvement of the whole person, spirit, soul and body. The bodily postures that the congregation adopts at Mass-- whether standing, kneeling, or sitting--accord with the nature of the rites being celebrated. Before Mass begins, members of the congregation or assembly, once they have entered the church and genuflected in adoration before the tabernacle, normally sit in silence in their pew, perhaps after kneeling briefly to offer a few preparatory prayers. As Mass begins with the entrance song and procession, all stand in acknowledgement that Christ, the High Priest, is present in the Eucharistic assembly to lead it in the worship of His heavenly Father. The congregation remains standing throughout the Mass's Introductory Rites: the Sign of the Cross and Greeting, the Act of Penitence, the Gloria, and the Collect. These rites dispose the congregation to a grateful and attentive reception of the word of God that will be proclaimed in the Liturgy of the Word that follows.
