I think that if someone has the tabernacle key and treats the hosts reverently, itâs a pretty sure bet he or she is an Extraordinary Minister of Holy Communion (EMHC), and you need not be concerned.
However, for clarity I would recommend you not confuse EMHCs with âeucharistic ministersâ (youâve done so twice), which are only priests
(in persona Christi)
, nor with âordinary ministers of Holy Communionâ, which are only bishops, priests and deacons (those who have been ordained).
For a more complete and official explanation on this, you might want to read
Redemptionis Sacramentum, Paragraphs 154-156, which state:
[154.] As has already been recalled, âthe only minister who can confect the Sacrament of the Eucharist
in persona Christi is a validly ordained Priestâ.
[254] Hence the name âminister of the Eucharistâ belongs properly to the Priest alone. Moreover, also by reason of their sacred Ordination, the ordinary ministers of Holy Communion are the Bishop, the Priest and the Deacon,
[255] to whom it belongs therefore to administer Holy Communion to the lay members of Christâs faithful during the celebration of Mass. In this way their ministerial office in the Church is fully and accurately brought to light, and the sign value of the Sacrament is made complete.[155.] In addition to the ordinary ministers there is the formally instituted acolyte, who by virtue of his institution is an extraordinary minister of Holy Communion even outside the celebration of Mass. If, moreover, reasons of real necessity prompt it, another lay member of Christâs faithful may also be delegated by the diocesan Bishop, in accordance with the norm of law,
[256] for one occasion or for a specified time, and an appropriate formula of blessing may be used for the occasion. This act of appointment, however, does not necessarily take a liturgical form, nor, if it does take a liturgical form, should it resemble sacred Ordination in any way. Finally, in special cases of an unforeseen nature, permission can be given for a single occasion by the Priest who presides at the celebration of the Eucharist.
[257][156.] This function is to be understood strictly according to the name by which it is known, that is to say, that of extraordinary minister of Holy Communion, and not âspecial minister of Holy Communionâ nor âextraordinary minister of the Eucharistâ nor âspecial minister of the Eucharistâ, by which names the meaning of this function is unnecessarily and improperly broadened.Hereâs the Vatican link online:
