They should, however, sit while the readings before the Gospel and the responsorial Psalm are proclaimed and for the homily and while the Preparation of the Gifts at the Offertory is taking place; **and, as circumstances allow, they may sit or kneel while the period of sacred silence after Communion is observed.
**
In the dioceses of the United States of America, they should kneel beginning after the singing or recitation of the Sanctus until after the Amen of the Eucharistic Prayer, except when prevented on occasion by reasons of health, lack of space, the large number of people present, or some other good reason. Those who do not kneel ought to make a profound bow when the priest genuflects after the consecration. **The faithful kneel after the Agnus Dei unless the Diocesan Bishop determines otherwise.53
**
**With a view to a uniformity in gestures and postures during one and the same celebration, the faithful should follow the directions which the deacon, lay minister, or priest gives according to whatever is indicated in the Missal.
**
44. Among gestures included are also actions and processions: of the priest going with the deacon and ministers to the altar; of the deacon carrying the Evangeliary or Book of the Gospels to the ambo before the proclamation of the Gospel; of the faithful presenting the gifts and coming forward to receive Communion. It is appropriate that actions and processions of this sort be carried out with decorum while the chants proper to them occur, in keeping with the norms prescribed for each.
