61) For it is clear that the pope’s power is of itself sufficient for the remission of penalties and cases reserved by himself.
The pope can dismiss the penalty of standards he sets, not the standards God sets.
62) The true treasure of the church is the most holy gospel of the glory and grace of God.
The gospel alone is the true treasure which is available to all for free.
63) But this treasure is naturally most odious, for it makes the first to be last (Mt. 20:16).
A bit of sarcasm from Luther saying in the ways of Jesus those who are most “holy” are actually those who are last in the hierarchy. The pope and others in the upper hierarchy don’t like this.
64) On the other hand, the treasure of indulgences is naturally most acceptable, for it makes the last to be first.
Those who buy forgiveness love indulgences because they aren’t following Christ, but get to end up ahead.
65) Therefore the treasures of the gospel are nets with which one formerly fished for men of wealth.
Sharing the gospel with wealthy people is for the sake of their souls not their gold.
66) The treasures of indulgences are nets with which one now fishes for the wealth of men.
With indulgences it doesn’t matter if they are rich or poor. The idea is to go after everybody’s money.
67) The indulgences which the demagogues acclaim as the greatest graces are actually understood to be such only insofar as they promote gain.
Indulgences are awesome not because of what they supposedly do, pay off penalty of sin, but because of what they really do, raise money for the pope.
68) They are nevertheless in truth the most insignificant graces when compared with the grace of God and the piety of the cross.
Indulgences don’t compare to real forgiveness.
69) Bishops and curates are bound to admit the commissaries of papal indulgences with all reverence.
The church hierarchy treats indulgences as all-holy.
70) But they are much more bound to strain their eyes and ears lest these men preach their own dreams instead of what the pope has commissioned.
The effectiveness of the indulgence correlates to the wishes of the pope. They are not sold for the dreams of others.
