You betray your own lack of education again. It's called the "Catholic Church," not the "Roman Catholic Church."The Roman Catholic Church preaches a false Gospel. And I know good and well what indulgences are. Clearly you didn't catch the point I was making. I am not saying that this sale is a way to get out of purgatory. I am saying that indulgences, which had zero real effect, were just a way to put money in the church coffers. This is no different.
If the sale of the device was not connected with lessening time in purgatory, it couldn't be an indulgence. Trying being more precise when using words.
Today while there are still indulgences, they aren't putting money in church coffers. Your honestly don't have a clue about what you're talking about.
