I. Who Celebrates?

From The Catechism of the Catholic Church

1142
But “the members do not all have the same function.”¹²
Certain members are called by God, in and through the Church, to a special
service of the community. These servants are chosen and consecrated by the
sacrament of Holy Orders, by which the Holy Spirit enables them to act in the
person of Christ the head, for the service of all the members of the
Church.¹³ The ordained minister is, as it were, an “icon” of
Christ the priest. Since it is in the Eucharist that the sacrament of the
Church is made fully visible, it is in his presiding at the Eucharist that the
bishop’s ministry is most evident, as well as, in communion with him, the
ministry of priests and deacons.
