First of all, none of us should ever write into a prayer accusations against other persons, esp. the Pope, or a rejection of decisions of holy Mother Church on doctrine or discipline, or a rejection of scientific-based efforts to help the sick. This is not a prayer, but an expression of Vigano’s malice toward the Church, of which the Virgin Mary is the pure image, and vice versa. His prayer assumes that he is right, and the Church as well as the medical authorities are gravely wrong.
Sometimes prayers of the faithful at Mass are written in this manner, asking that God cause people to…to act the way that the person writing the pray wishes.
There is also a direct but subtle attack on the papal magisterium, where Vigano claims that certain persons are preparing for the reign of the Antichrist. Then, too, he speaks as if the indefectible Church has gone astray.
Where Vigano says “the forces of the Enemy are multiplying their infernal assault”, he refers to the Pope and Bishops, who do not act as Vigano would like. He also references Mary as co-redemptrix, a term that Pope Francis has set aside (for now).
