One of the aspects of Christianity that I often hear cited for it's popularity in Rome was equality in death, that the rich and the poor had the same two options for the afterlife. Considering how stratified the high and late medieval periods were, and how the churches themselves had beautiful effigies of the lords who built them, not John the cottar, as well as the fact that a lot of the clergy came from noble families, do we know how much this was portrayed?

As a secondary question, do we know how it played into their understanding of class hierarchy?
