Can a priest sit down and let lay ministers distribute Communion?

[theors]

After the consecration at mass, our pastor (a monsignor) distributes the Eucharist to the lay ministers and altar assistants,
then sits down and lets the lay ministers distribute the Eucharist to the faithful. Our pastor is not disabled or infirm. I have always
understood this to be a no-no, that the celebrant MUST distribute
the Eucharist and can be assisted by a lay minister.

Am I right or am I wrong. Please clear this up for me.

 

[Peggy_Frye]

It is prohibited for priests who, “even though present at the celebration, abstain from distributing Communion and hand this function over to laypersons.”
Redemptionis Sacramentum [157].

[157.] If there is usually present a sufficient number of sacred ministers for the distribution of Holy Communion, extraordinary ministers of Holy Communion may not be appointed. Indeed, in such circumstances, those who may have already been appointed to this ministry should not exercise it. The practice of those Priests is reprobated who, even though present at the celebration, abstain from distributing Communion and hand this function over to laypersons.

[158.] Indeed, the extraordinary minister of Holy Communion may administer Communion only when the Priest and Deacon are lacking, when the Priest is prevented by weakness or advanced age or some other genuine reason, or when the number of faithful coming to Communion is so great that the very celebration of Mass would be unduly prolonged.259 This, however, is to be understood in such a way that a brief prolongation, considering the circumstances and culture of the place, is not at all a sufficient reason.

Inaestimabile Donum

1. 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.(20) Accordingly, a reprehensible attitude is shown by those priests who, though present at the celebration, refrain from distributing Communion and leave the task to the laity.
