Extraordinary ministers of Holy Communion may be appointed in parishes in situations of genuine pastoral need where ordinary ministers are not available or are insufficient in number to facilitate the distribution of Holy Communion within Mass when there is a large number of communicants.

This allows for more frequent and daily administration of Holy Communion outside of Mass to those impeded from attending Mass because of sickness or physical weakness. Extraordinary ministers of Holy Communion assist priests and deacons in administering Holy Communion.
