Thank you for that response, but respectfully, notwithstanding what may well be the long history of equating the Holy Eucharist to the Mass, I have never heard the word being used as a substitute for the Holy Mass since I have been receiving Holy Communion in the early 1940s. Indeed, even then we referred to Holy Communion as the Holy Eucharist, interchangably.
But now, actually suddenly, referring the Holy Mass is to be known as a Eucharist. I haven't raised this question with a priest from the SSPX (where I regularly assist), but I have never heard anyone at our church refer to the Mass in that way.
have no firm basis for suggesting this (that's why I posed the question), but I strongly suspect it is related to the false ecumenism of Vatican II.
The Protestants detest any reference to the Mass as a "sacrifice" and (like many modern priests and followers of the Novus Ordo Mass), call it a "supper"--which, appropriately, might well be consider a "thanksgiving." Nevertheless, that is not Catholic.

Respectfully, Christopher, when you stand before God you will judged as a Catholic on your faithfulness to the true teachings of the Church. Your complaints against Pope Francis and his support for homosexuals won't amount to a row of pins. You would please God and do well for yourself by seeking out and regularly assisting at a TLM being offered by a priest faithful to all the true, pre-Vatican II teachings of the Catholic Church.

It is almost a certainty that Demos II did not receive his Red hat from Pope Francis. And if he is a cardinal under 80 by the time Pope Francis moves on he'll only have one vote.
It would also be surprising to learn that his thoughts as set forth in his text would have much impact, if any, on a majority of the other voting cardinals who were made by Pope Francis.
Still anything is possible with God. Prayer is the only answer.

He's obviously confused because the Catholic Church does not make mistakes. The Catholic Church is the Mystical Body of Christ.

Like many others, he also believes that the popes, bishops and priests of the counterfeit Conciliar Church (the shadow church that grew out of Vatican II) is the Catholic Church. He could not be more wrong.

But even though the leaders of the Conciliar Church have the buildings, the authority, and hold the reins of power, they cannot change the true teachings of the Catholic Church. Those who witness at the Novus ordo mass and believe the teachings of Conciliarist leaders are very foolish.

A somewhat analogous scenario is playing out in America, whereby key elected government leaders are also wear the hats of the Deep State--the unannounced organization which has surreptitiously assumed the reins of power and leads this nation from the shadows. Like the pope and the bishops, they lead their followers to destruction.

But, unlike the Catholic Church which Jesus Christ has assured us will prevail against the Gates of Hell intel the end of time, America's government "by the people" does not enjoy that promise. It's simply a matter of time before America becomes just another community in a world government.

I don't understand why does Gloria.tv refers to the Holy Sacrifice of the Mass as a "Eucharist?" When I first began to see that expression appearing in Conciliar publications in recent times I suspected it was another Modernist step in their plan of promoting their false ecumenism, or further equating the Holy Mass to the Last Supper rather than the Sacrifice on Calvary. Now that Gloria.tv is using it I'm confused.
Perhaps there's a plausible explanation that I've missed for this apparent change, but like referring to Catholics as "Christians," despite the fact that the name changes may be technically correct, if the earlier names for the Holy Mass and Catholics were appropriate for some two millennium, I see no good reason to change.
I would sincerely welcome any thoughts faithful Catholics might have on this point.
