" It is this people, then, the priestly people, the body of Christ and the community of Christ, who are the ‘subject’ of liturgical celebrations. In other words, it is they who celebrate the liturgy, and the form of the liturgy must be of such sort as to make this possible. The Christian liturgy by its nature cannot be the monologue of a single participant. It is the action of a whole community. On the other hand, it is not an unstructured community. Each member, and indeed each group of members (e.g. the choir), has its role to fulfil and all by these funcitons are exercising the priesthood that they share with Christ and Chruches, an indispensable part of this structure is the priesthood, which is a ministry...of the priesthood of Christ and is in no way opposed to the priesthood of the people but is complementary to it. There is but one priesthood, that of Christ, which the whole Church exists to seve and make actual in the here and now. In the liturgical assembly the ministers of Christ have a special role of leading, of presiding, of preaching of uniting all in self-offering with Christ. For their part, the people not only act and offer through the priest-celebrant, they act and offer with him. By virtue of their baptism, they share in the priesthood of Christ and...they have their various roles to perform. "
