It will not surprise those who have observed the effect of all persecution for matters of opinion upon the human mind, that during this period the Romish party continued such in numbers and in zeal as to give the most lively alarm to Elizabeth's administration. One cause of this was beyond doubt the connivance of justices of the peace, a great many of whom were secretly attached to the same interest, though it was not easy to exclude them from the commission, on account of their wealth and respectability.[226] The facility with which catholic rites can be performed in secret, as before observed, was a still more important circumstance. Nor did the voluntary exiles established in Flanders remit their diligence in filling the kingdom with emissaries. The object of many at least among them, it cannot for a moment be doubted, from the æra of the bull of Pius V., if not earlier, was nothing less than to subvert the queen's throne. They were closely united with the court of Spain, which had passed from the character of an ally and pretended friend, to that of a cold and jealous neighbour, and at length of an implacable adversary. Though no war had been declared between Elizabeth and Philip, neither party had scrupled to enter into leagues with the disaffected subjects of the other. Such sworn vassals of Rome and Spain as an Allen or a Persons, were just objects of the English government's distrust: it is the extension of that jealousy to the peaceful and loyal which we stigmatise as oppressive, and even as impolitic.[227]
