Reply: Assuredly, the Eucharistic celebration is the act of the entire community, carried out by all the members of the liturgical assembly. Nevertheless, everyone must have and also must observe his or her own place and proper role: “In liturgical celebrations each one, minister or layperson, who has an office to perform, should do all of, but only, those parts which pertain to that office by the nature of the rite and the principles of liturgy.” (SC art. 29). During the liturgy of the eucharist, only the presiding celebrant remains at the altar. The assembly of the faithful take their place in the Church outside the “presbyterium,” which is reserved for the celebrant or concelebrants and altar ministers.
