MOVEMENTS AND POSTURES

20. The uniformity in standing, kneeling, or sitting to be observed by all taking part is a sign of the community and the unity of the assembly; it both expresses and fosters the spiritual attitude of those taking part.²⁸

21. For the sake of uniformity in movement and posture, the people should follow the directions given during the celebration by the deacon, the priest, or another minister. Unless other provision is made, at every Mass the people should stand from the beginning of the entrance song or when the priest enters until the end of the opening prayer or collect; for the singing of the Alleluia before the gospel; while the gospel is proclaimed; during the profession of faith and the general intercessions; from the prayer over the gifts to the end of the Mass, except at the places indicated later in this paragraph. They should sit during the readings before the gospel and during the responsorial psalm, for the homily and the presentation of the gifts, and, if this seems helpful, during the period of silence after communion. They should kneel at the consecration unless prevented by the lack of space, the number of people present, or some other good reason.

But it is up to the conference of bishops to adapt the actions and postures described in the Order of the Roman Mass to the customs of the people.²⁹ But the conference must make sure that such adaptations correspond to the meaning and character of each part of the celebration.

22. Included among the external actions of the Mass are those of the priest going to the altar, of the faithful presenting the gifts, and their coming forward to receive communion. While the songs proper to these movements are being sung, they should be carried out becomingly in keeping with the norms prescribed for each.
