“The Roman view is that works earn extra grace.”
I know lot of Protestants who believe that. “Jewels in the crown”. I had a Pentecostal friend who believed in “levels of Heaven” for the more pious.
For most of our existence, we’ve had a messed up view of Grace. I’m not sure any church really believed in it until just recently. For much of my life, Grace came at a price.
What the Roman church did was monetize Salvation. It was never freely given.
The greatest example of irony was, that for centuries, the Church of Jesus Christ would torture and execute you for speaking against the teachings and practices of the church. Let that sink in for a moment.
I'm still having trouble finding the chapter and verse where Jesus tells us to treat others who disagree with us like that.
