Did you read the last few words of the prayer you quoted above? Bolding and underlining mine. The Bread of Life is the Holy Eucharist according to John 6 (6:24-60, the Bread of Life discourse). So the prayer you quoted is in fact a perfectly Catholic description of the Catholic doctrine of Transubstantiation. You do believe in Transubstantiation, right?

Can you address this from Archbishop Lefebvre? "“Should all the world’s churches be emptied? I do not feel brave enough to say such a thing. I don’t want to encourage atheism."[10.]”
Here, Archbishop Lefebvre [+ABL] precisely expresses the Truth that telling Roman Catholics to empty all Diocesan Churches encourages only Atheism.
A 2nd time: “if one does not have the choice and if the priest celebrating Mass according to the Novus Ordo is faithful and worthy, one should not abstain from going to Mass.”[44]”

So according to Archbishop Lefebvre, you are "encouraging Atheism". It is a poisonous doctrine to say the NOM is supposedly evil, rather than being only an inferior form of the Holy Sacrifice of the Mass. Also, the bread does not remain mere bread, therefore it is no longer the "fruit of the earth". It is the Bread of Life, the True Body of Christ.

Here are some additional prayers from the NOM. Do they look like idolatrous non-Catholic worship to you? In Eucharistic Prayer IV: “It is truly right to give you thanks, truly just to give you glory, Father, most holy, for you are the One God living and true, existing before all ages and abiding for all eternity, dwelling in unapproachable light; yet you, who alone are good, the source of life, have made all that is, so that you might fill your creatures with blessings and bring joy to many of them by the glory of your light. And so, in your presence are countless hosts of Angels, who serve you day and night and, gazing upon the glory of your face, glorify you without ceasing. With them we, too, confess your name in exultation, giving voice to every creature under heaven as we acclaim:” This is worship of the True God, the Eternal Father, with His Son and His Spirit. And here is EP III which underlines the same point: “You are indeed Holy, O Lord, and all you have created rightly gives you praise, for through your Son our Lord Jesus Christ, by the power and working of the Holy Spirit, you give life to all things and make them holy, and you never cease to gather a people to yourself, so that from the rising of the sun to its setting a pure sacrifice may be offered to your name.” This is a reference to Malachi 1:11, which prophesies the Holy Sacrifice of the Mass. It affirms Catholic doctrine. You have embraced Protestant opinions about the Magisterium, believing it can defect or give evil. The Church affirms every doctrine affirmed at Trent.

Blessed are you, Lord God of all creation, for through your goodness we have received the bread we offer you: fruit of the earth and work of human hands, it will become for us the bread of life.

Yes, I read all the words. Here it is again, with both my (in red) and your emphasis (bold black and underlined):

What if Cain said the same thing? What if he said his "fruit of the earth" would become for him the "bread of life"? The offering doesn't change because Cain thinks it something it isn't - it remains an unacceptable sacrifice to God. It's not the "firstborn" victim, a living sacrificial host that signifies the "firstborn" from the dead, Christ. Abel, in offering the "firstling" of his flock, was offering the only acceptable sacrifice, Christ.

Cain could have also said all those other things the Novus Ordites say as well. As with the apostates of the Novus Ordo, if you asked him, he would have said his offering was to God as well, offered for His glory, etc. God said it wasn't an acceptable offering. Case closed.

The "fruit of the earth" is the false offering of Cain, and remains a false offering even if Cain thought it was a true offering.

God doesn't want the offering of human hands from man's cursed tilling of the soil (see Genesis 3:17, "cursed is the earth in your work"), which can't save anything. He will only accept the offering of His Son.

I wouldn't want to be standing in your shoes before God when you try to justify the offering of Cain, literally the same "fruit of the earth," the same rejected human work.

In the movie Bambi, the rabbit Thumper said to Bambi, "you can call me a flower if you want to." That won't work with God. You can't make the false offering of the "fruit of the earth" into the offering of Christ by calling it what it isn't.
