So I've listened to about the first 17 minutes of the video posted by OP, and it's really fascinating.
Are these docuмents legitimately written by and to Bugnini himself?
He emphasizes replacing the offertory, replacing the Our Lord as the Victim being offered, with the offering of the bread and wife, the fruits of the earth. And he recalls how God was pleased with the sacrifice of Abel, who sacrificed animals, but displeased with Cain who offered the "fruits of the earth". So the intent was to deliberately call to mind the DISPLEASING sacrifice of Cain to God vs. the pleasing sacrifice of Abel.
Of course, this section alone, the destruction of the Offertory, completely vitiates the Sacrifice of the Mass. Instead of offering Our Lord Himself to God, we offer some bread and wine, the "work of human hands".
I also recall that this expression resembles some Jєωιѕн prayer.
But if these docuмents are legitimate, it shows that this NOM was deliberately engineered to displease God. At first I thought it may have been done in an "Ecuмenical spirit" ... but it would appear that the spirit was entirely diabolical. I have long suspected that all this destruction was done deliberately, in bad faith, by conscious enemies of the Church, but this seems to back it up with some real evidence.
Does anyone have a link to the written article as his automated reader is a bit annoying (though better than most)? I'd like to actually see the prints of those letters that appear to have been written by Bugnini himself.
So Bugnini calls this the "Ace up [his] sleeve" where he vitiates the Catholic Mass where "nobody [would] notice".
