I’d agree with this although I hasten to add that I’m not intending to cast spurious judgments on the priest referred to by the OP! Sadly, I have come across priests who leave the distribution of communion to EMHCs often out of a misguided idea of being pastoral. In other words, there are more ministers (ordinary and extraordinary) than are required so the priest sits down so an EHMC doesn’t have to. However this misunderstands both the role of the priest and of the EMHC. If they’re properly trained, the EHMC won’t have a problem with dropping out, so to speak.
IMHO: The vocation “crisis” has very little to do with the use of EMHC and more to do with the ever increasing attack upon the Family and the Church. Young men are constantly bombarded with messages from the media telling them that a hedonistic lifestyle is the “cool” way to live. To become a priest one must sacrifice one’s self to the Body of Christ.
As for the priests you have observed “…acting out of some misguided thought…,” I think I more likely that you are not fully aware of some issue wherein the priest as a legitimate cause to use the EMHC in such manner. I highly doubt, especially since
Inaestimabile donum, that the priest would be abusing the proper use of EMHC and if he is, then it is a matter that someone in that parish should take up with the Pastor. As for properly trained EMHC dropping out, the EMHC are doing as asked, presumably by their Pastor, it is not their place to tell the Pastor… “I’m dropping out because I think you have too many EMHC” it is the Pastor’s place to decide who and how many are to assist him during the Mass.
Normally the scheduled EMHC don’t show up in my Parish so we’re combing the pews for volunteers. There has been at least three occasions where I have ended up being Lector, EMHC. and Usher because people didn’t show up and no-one would come up despite a direct appeal from the Priest, from the Dais, for help. 300 people, 2 annexes, no Deacon and at least 5 people I know personally that could have helped and not a single one of them so much as blinked an eye. Sad, so Sad.
No, there’s not a vocation crisis because of EMHC, there’s a vocation crisis because too many people ask first, “what’s in it for me?” and the devil plugs their ears, blinds their eyes, and hardens their hearts so that they cannot hear, see, nor feel the Holy Spirit.
