With great adroitness, he evaded the vigilance of the custom-house officers, and the more vigilant spies of the Inquisition, and in the end succeeded in landing two large casks filled with prohibited works, which were quickly distributed among the members of the infant church. Other intrepid converts followed the example of Hernandez, and with similar success; so that, with the aid of books and spiritual teachers, the number of the faithful multiplied daily throughout the country.[434] Among this number was a much larger proportion, it was observed, of persons of rank and education than is usually found in like cases; owing doubtless to the circumstance that it was this class of persons who had most frequented the countries where the Lutheran doctrines were taught. Thus the Reformed Church grew and prospered, not indeed as it had prospered in the freer atmospheres of Germany and Britain, but as well as it could possibly do under the blighting influence of the Inquisition; like some tender plant, which, nurtured in the shade, waits only for a more genial season for its full expansion. That season was not in reserve for it in Spain. It may seem strange that the spread of the Reformed religion should so long have escaped the detection of the agents of the Holy Office. Yet it is certain that the first notice which the Spanish inquisitors received of the fact was from their brethren abroad. Some ecclesiastics in the train of Philip, suspecting the heresy of several of their own countrymen in the Netherlands, had them seized and sent to Spain, to be examined by the Inquisition. On a closer investigation, it was found that a correspondence had long been maintained between these persons and their countrymen, of a similar persuasion with themselves, at home. Thus the existence, though not the extent, of the Spanish Reformation was made known.[435] No sooner was the alarm sounded, than Paul the Fourth, quick to follow up the scent of heresy in any quarter of his pontifical dominions, issued a brief, in February, 1558, addressed to the Spanish inquisitor-general. In this brief, his holiness enjoins it on the head of the tribunal to spare no efforts to detect and exterminate the growing evil; and he empowers that functionary to arraign and bring to condign punishment all suspected of heresy, of whatever rank or profession,--whether bishops or archbishops, nobles, kings, or emperors. Paul the Fourth was fond of contemplating himself as seated in the chair of the Innocents and the Gregories, and like them setting his pontifical foot on the necks of princes. His natural arrogance was probably not diminished by the concessions which Philip the Second had thought proper to make to him at the close of the Roman war.
