The next considers whether it is correct for a bishop to act as a concelebrant at a priest`s jubilee Mass so that the jubilarian can be main celebrant. I must admit I`ve always been uneasy with bishops concelebrating at a Mass where the main celebrant is a priest. The comment is made: " Theologically the bishop must always preside, even if he does so in choir dress and presides over the Liturgy of the Word but does not concelebrate. This is provided in Caerimoniale Episcoporum no.18."It has always struck me as being exceedingly odd for a bishop to pretend not to be a bishop, and just one of the lads but then I have met more than one or two bishops who just don't know how to say Mass, they have never read the rubrics. One young priest I know said, "I never look when concelebrating with my bishop". A real case for a Bishop learning both forms of his Rite!
.... Caerimoniale no. 18 which says:
When a bishop presides at the eucharist but is not the celebrant, he does everything in the liturgy of the word that belongs to the celebrant and he concludes the Mass with the rite of dismissal, following the provisions given in nos 176-185.
176-185 say the bishop is to vest in alb, stole, cope and mitre so this seems to extend the possibility to him presiding over the liturgy of the Word in choir dress.
The third response concerns whether it is correct for concelebrants to elevate chalices at the end of the Eucharistic prayer. This too is reprobated. The comment is : "The purpose of this elevation is not to show the consecrated elements to the people but to express the giving of glory to God. Only the celebrant with the assistance of a deacon for the chalice should do this."I just hate that, "let's all show them the silverware" moment.
