Paying for reduction in purgatory time. For along time the Church told people that the pope was Christ on earth. If you paid him he would give you less time in purgatory.
Um - no. What happened was, using the power of the keys (Matthew 16:18-19) the Pope offered an Indulgence to people who gave money to his building projects (the Sistine Chapel, for example, and the work that was being done there by Michelangelo, especially the paintings on the ceiling - which by the way I notice are continually being reproduced even in Protestant books and on Protestant videos, so I think we all agree that those paintings are inspirational and help us to know God better - and without the money, this certainly would not have been done).
To receive the Indulgence, the person would, say for example, give some money to Michelangelo so that he could buy some paint for this project, and maybe have something to eat, pay his rent, and stuff like that.
The person would then pray one Our Father and one Hail Mary for the intentions of the Pope, go to Confession, and receive Holy Communion. Then
God (not the Pope) would
remit the temporal punishment for sins
already forgiven. But whether or not he did this, in the first place, would be between him and God. Nobody in the world - nt the Pope or anybody - would know that the person had collected an Indulgence (that is, said the prayers, gone to Confession, and received Holy Communion) for sending in the money for this project.
The money had to be raised
anyway. The Pope offered an Indulgence for it because the project was of spiritual value to the whole Church. In those days, instead of offering an Indulgence for free-will offerings, he could have easily asked the feudal lords to impose a tax, and paid for it that way. It would certainly have improved Michelangelo’s cash flow, if he had, and the project would have been done years earlier (since Michelangelo often had to stop working on the project in order to get paying jobs, to keep body and soul together, when the whole “selling Indulgences” myth got started, and the money quit coming in.)
