the roman catholic church does permit communion services, led by lay people, on weekdays. Redemptionis sacramentum has:
“[166.] likewise, especially if holy communion is distributed during such celebrations, the
diocesan bishop, to whose exclusive competence this matter pertains, must not easily grant
permission for such celebrations to be held on weekdays, especially in places where it was
possible or would be possible to have the celebration of mass on the preceding or the
following sunday.”
if the church did not permit these celebrations it would not say “must not easily grant permission”. It would say “may never grant permission”. Redemptionis sacramentum can be looked up at

Fr david wrote “someone rightly quoted documents which say that communion outside of mass may be distributed on any day (a few exceptions), but that does not refer to services led by laypeople—it’s a reference to communion given to the sick or shut-ins or inmates, etc”. It is absurd to say this does not refer to services led by laypeople. The document i quoted was holy communion and the worship of the eucharist outside of mass, n. 16. The very next paragraph has the heading “the minister of communion”.
“17. It belongs first of all to the priest and the deacon to minister communion to the faithful who ask to receive it. … It also belong to the an acolyte who has been properly instituted to give communion as a special minister when the priest and deacon are absent … The local ordinary may give other special ministers the faculty to give communion whenever it seems necessary for the pastoral benefit of the faithful and no priest, deacon, or acolyte is available.” (the rites volume one, liturgical press, 1990, isbn: 0-8146-6015-0, pages 644-645).
What difference does it make whether people are sick or shut-ins? How does the ceremony stop being a “communion service” in that case?
