Even if [the Pope an incarnate devil], we ought not to raise up our heads against him, but calmly lie down to rest on his bosom... He who rebels against our Father is condemned to death, for that which we do to him we do to Christ: we honor Christ if we honor the Pope; we dishonor Christ if we dishonor the Pope.
St. Catherine of SienaChrist Jesus left you this sweet key of obedience; for He left His Vicar, whom you are all obliged to obey until death. And whoever is outside his obedience is in a state of damnation.
St. Catherine of Siena
