The non-ordained faithful already collaborate with the sacred ministers in diverse pastoral situations since “This wonderful gift of the Eucharist, which is the greatest gift of all, demands that such an important mystery should be increasingly better known and its saving power more fully shared”.(95)
Such liturgical service is a response to the objective needs of the faithful especially those of the sick and to those liturgical assemblies in which there are particularly large numbers of the faithful who wish to receive Holy Communion.
§ 1. The canonical discipline concerning extraordinary ministers of Holy Communion must be correctly applied so as to avoid generating confusion. The same discipline establishes that the ordinary minister of Holy Communion is the Bishop, the Priest and the the Deacon.(96) Extraordinary ministers of Holy Communion are those instituted as acolytes and the faithful so deputed in accordance with Canon 230, § 3.(97)
A non-ordained member of the faithful, in cases of true necessity, may be deputed by the diocesan bishop, using the appropriate form of blessing for these situation, to act as an extraordinary minister to distribute Holy Communion outside of liturgical celebrations ad actum vel ad tempus or for a more stable period. In exceptional cases or in un foreseen circumstances, the priest presiding at the liturgy may authorize such ad actum .(98)
§ 2. Extraordinary ministers may distribute Holy Communion at eucharistic celebrations only when there are no ordained ministers present or when those ordained ministers present at a liturgical celebration are truly unable to distribute Holy Communion.(99) They may also exercise this function at eucharistic celebrations where there are particularly large numbers of the faithful and which would be excessively prolonged because of an insufficient number of ordained ministers to distribute Holy Communion.
