It is a reflection when Bergoglio uses them: He used the "Great Accuser" in his feeble attempt to brush off Archbishop Vigano's scathing indictment.
"Sourpuus", ""Pickled pepper-faced Christian!", "Creed-reciting, parrot Christian!", "rosary counter", "Self-absorbed, Promethean neo-Pelagian!", "A simple numerary in this sect!" are all reflections on living persons: traditional Catholics.
Wow, can you imagine if any other world or religious leader called his subjects these names?
