This Eucharistic Miracle stuff is part of the larger deception of the Antichrist. This is referred to in Apocalypse 13:13:

13 And he did great signs, so that he made also fire to come down from heaven unto the earth in the sight of men

The "fire to come down from heaven" is a reference to Elijah on Mt. Carmel in his test of the False Priests of Baal (read the passage from 1 Kings 18:16-40 below).

Fire coming down from heaven is a figure of the consecration of the Eucharist. So the Apocalypse is saying that Antichrist will do what the False Priests of Baal failed to do. He will deceive people in to believing a Eucharistic consecration (miracle) occurs when it actually does not.

Bergoglio and his Buenos Aires fake "Eucharistic miracle" is the source of all of this. And the canonization of Carlo Acutis is the vehicle publicizing the fake event. The end goal, again, is to "validate" the Novus Ordo Eucharist and the Novus Ordo Mass as pleasing to God because of the Real Presence.

Sadly, most people, especially those with "itching ears (2 Timothy 4:3)," will fall for it.

Elijah on Mount Carmel

16Abdias therefore went to meet Achab, and told him: and Achab came to meet Elias. 

17And when he had seen him, he said: Art thou he that troublest Israel?  18And he said: I have not troubled Israel, but thou and thy father's house, who have forsaken the commandments of the Lord, and have followed Baalim.

19Nevertheless send now, and gather unto me all Israel, unto mount Carmel, and the prophets of Baal four hundred and fifty, and the prophets of the groves four hundred, who eat at Jezabel's table. 

20Achab sent to all the children of Israel, and gathered together the prophets unto mount Carmel.  21And Elias coming to all the people, said: How long do you halt between two sides? if the Lord be God, follow him: but if Baal, then follow him. And the people did not answer him a word.  22And Elias said again to the people: I only remain a prophet of the Lord: but the prophets of Baal are four hundred and fifty men.  23Let two bullocks be given us, and let them choose one bullock for themselves, and cut it in pieces and lay it upon wood, but put no fire under: and I will dress the other bullock, and lay it on wood, and put no fire under it.  24Call ye on the names of your gods, and I will call on the name of my Lord: and the God that shall answer by fire, let him be God. And all the people answering said: A very good proposal. 

25Then Elias said to the prophets of Baal: Choose you one bullock and dress it first, because you are many: and call on the names of your gods, but put no fire under.  26And they took the bullock which he gave them, and dressed it: and they called on the name of Baal from morning even till noon, saying: O Baal, hear us. But there was no voice, nor any that answered: and they leaped over the altar that they had made.  27And when it was now noon, Elias jested at them, saying: Cry with a louder voice: for he is a God, and perhaps he is talking, or is in an inn, or on a journey, or perhaps he is asleep, and must be awaked. 28So they cried with a loud voice, and cut themselves after their manner with knives and lancets, till they were all covered with blood.  29And after midday was past, and while they were prophesying, the time was come of offering sacrifice, and there was no voice heard, nor did any one answer, nor regard them as they prayed: 

30Elias said to all the people: Come se unto me. And the people coming near unto him, he repaired the altar of the Lord, that was broken down:  31And he took twelve stones according to the number of the tribes of the sons of Jacob, to whom the word of the Lord came, saying: Israel shall be thy name.  32And he built with the stones an altar to the name of the Lord: and he made a trench for water, of the breadth of two furrows round about the altar.  33And he laid the wood in order, and cut the bullock in pieces, and laid it upon the wood.  34And he said: Fill four buckets with water, and pour it upon the burnt offering, and upon the wood. And again he said: Do the same the second time. And when they had done it the second time, he said: Do the same also the third time. And they did so the third time. 

35And the water run round about the altar, and the trench was filled with water. 

36And when it was now time to offer the h0Ɩ0cαųst, Elias the prophet came near and said: O Lord God of Abraham, and Isaac, and Israel, shew this day that thou art the God of Israel, and I thy servant, and that according to thy commandment I have done all these things.  37Hear me, O Lord, hear me: that this people may learn, that thou art the Lord God, and that thou hast turned their heart again.  38Then the fire of the Lord fell, and consumed the h0Ɩ0cαųst, and the wood, and the stones, and the dust, and licked up the water that was in the trench.  39And when all the people saw this, they fell on their faces, and they said: The Lord he is God, the Lord he is God.  40And Elias said to them: Take the prophets of Baal, and let not one of them escape. And when they had taken them, Elias brought them down to the torrent Cison, and killed them there.
