MINISTRY OF HOLY COMMUNION
When the size of the congregation or the incapacity of the Bishop, priest, or deacon requires it, the celebrant may be assisted by other Bishops, priests, or deacons. If such ordinary ministers of Holy Communion are not present, “the priest may call upon extraordinary ministers to assist him, i.e., formally instituted acolytes or even some of the faithful who have been commissioned according to the prescribed rite. In case of necessity, the priest may also commission suitable members of the faithful for the occasion.” (Norms #28; General Instruction of the Roman Missal #162, 284)
The faculty is granted to pastors and priests-chaplains to appoint extraordinary ministers of Communion in their parishes or institutions.
