Stacking the Plates

Back to the religion dealie again, Fiorella thinks churches are like dishwashers. Everyone is invited in, but not all will not be cleansed. Sometimes the machine is at fault, sometimes the china. Sometimes the dishwasher powder gets stuck in the dispenser or the machine the machine is old and worn out. But sometimes the plate is too dirty to be cleaned by anything less than a blast furnace.

What Fiorella is trying to get at is that, even is the message is there, sometimes a listener doesn't hear it.
