71) Let him who speaks against the truth concerning papal indulgences be anathema and accursed.
Here Luther is cursing you if you disagree with him about the indulgences (He is the “one who speaks the truth”)
72) But let him who guards against the lust and license of the indulgence preachers be blessed.
Luther pronounces a blessing on those resisting the temptation of buying indulgences from these indulgence preachers.
73) Just as the pope justly thunders against those who by any means whatever contrive harm to the sale of indulgences.
Luther is giving the pope the benefit of the doubt of these indulgences. He is almost saying the pope is not aware of the indulgence preachers’ messages concerning them.
74) Much more does he intend to thunder against those who use indulgences as a pretext to contrive harm to holy love and truth.
Luther is saying the pope will see the way they are selling his indulgences is wrong.
75) To consider papal indulgences so great that they could absolve a man even if he had done the impossible and had violated the mother of God is madness.
One of the indulgence preachers’ favorite hyperboles is to say indulgences will even pardon the sin of raping Mary!
76) We say on the contrary that papal indulgences cannot remove the very least of venial sins as far as guilt is concerned.
Indulgences can’t forgive sin, period, even very tiny ones.
77) To say that even St. Peter if he were now pope, could not grant greater graces is blasphemy against St. Peter and the pope.
Peter is supposed to be the pope above all popes. But, these current indulgences are better than any he could grant. Again, ridiculous.
78) We say on the contrary that even the present pope, or any pope whatsoever, has greater graces at his disposal, that is, the gospel, spiritual powers, gifts of healing, etc., as it is written. (1 Co 12[:28])
This is only the third time Luther quotes scripture. It just shows the lack of respect the church hierarchy has for the Bible that Luther can’t use it more to in the debate. He is saying the gifts of God are already greater than any indulgence.
79) To say that the cross emblazoned with the papal coat of arms, and set up by the indulgence preachers is equal in worth to the cross of Christ is blasphemy.
When the indulgence preachers come into town, they have a banner of the pope’s coat of arms to show they represent the pope. They also carry a cross on which they post an indulgence, instead of a body of Jesus like a normal crucifix, signifying the indulgence has equal power as Christ on the cross.
80) The bishops, curates, and theologians who permit such talk to be spread among the people will have to answer for this.
The church leaders are wrong and they will be judged by God.
