They did not dare name explicitly the person of the Roman Pontiff, but, in fact, they have defined as extraneous to the Spanish Nation the authority of the Vicar of Christ, as if the authority of the Roman Pontiff, conferred by Jesus, Himself, could be called extraneous to any part of the world whatsoever; as if the recognition of the Divine Authority of Christ can minimize legitimate human authority; as if the spiritual and supernatural power could be in contrast with that of the State - a contrast that cannot exist except through the malice of those who desire and want it because they know that without the Shepherd little sheep would go astray and more easily become the prey of false shepherds.
