“With regard to the mystic body of Christ, that is, all the faithful, the priest has the power of the keys, or the power of delivering sinners from hell, of making them worthy of paradise, and of changing them from the slaves of Satan into the children of God. And God himself is obliged to abide by the judgment of his priests, and either not to pardon or to pardon, according as they refuse or give absolution, provided the penitent is capable of it. "
Such is," says St. Maximus of Turin, " this judiciary power ascribed to Peter that its decision carries with it the decision of God." 2 The sentence of the priest precedes, and God subscribes to it. .” – Dignity and Duties of the Priest, St. Alphonsus Ligouri, Vol. 12, p. 2 (whose writings were declared free from anything meriting censure by Pope Gregory XVL (1839) in the bull of his canonization). http://www.archive.org/stream/alphonsusworks12liguuoft/alphonsusworks12liguuoft_djvu.txt
I doubt one has to wonder at God’s attitude toward the priest who abuses his power by committing those atrocious acts. I can’t even imagine the mind gymnastics those Catholics have to go through who those priests did last rights for their relatives.
