Creating a meaningful and spirit-filled celebration of the Mass is truly a group effort. It takes numerous ministry groups, during preparation and celebration, for each Catholic Mass to run smoothly and with grace.
In liturgical celebrations each person, minister or layman, who has an office to perform, should do all of, but only, those parts which pertain to his office by the nature of the rite and the principles of liturgy.Sacrosanctum Concilium, #28
To promote active participation, the people should be encouraged to take part by means of acclamations, responses, psalmody, antiphons, and songs, as well as by actions, gestures, and bodily attitudes. And at the proper times all should observe a reverent silence.Sacrosanctum Concilium, #30
