Can extraordinary ministers or the faithful pick up the chalice and give themselves Holy Communion?
Inaestimabile donum, issued in 1980 states that:
9.Communion is a gift of the Lord, given to the faithful through the minister appointed for the
purpose. It is not permitted that the faithful should themselves pick up the consecrated bread and the sacred chalice; still less
that they should hand them from one to another.
10.The faithful, whether religious or lay, who are authorized as extraordinary ministers of the Eucharist can distribute
Communion only when there is no priest, deacon or acolyte, when the priest is impeded by illness or advanced age, or when
the number of the faithful going to communion is so large as to make the celebration of Mass excessively long.
Accordingly, a reprehensible attitude is shown by those priests who, though present at the celebration, refrain from distributing
Communion and leave this task to the laity.
When the U.S. bishops issued the directives for the distribution of Holy Communion under both kinds in the document This Holy and Living Sacrifice, they reaffirmed this statement:
46. The chalice may never be left on the altar or another place to be picked up by the communicant for self-communication
(except in the case of concelebrating bishops or priests), nor may the chalice be passed from one communicant to another.
There shall always be a minister of the cup.
