2. =The Anjou Marriage Treaty and the Ridolfi Plot. 1570-1571.=--For all that, Elizabeth's danger was great. In =1570= she had done her best to embroil parties in Scotland lest they should join against herself. The bulk of the nobility in that country had thrown themselves on the side of Mary, and were fighting against the new regent, Lennox, having taken alarm at the growth of the popular Church organisation of Knox and the Presbyterians, who sheltered themselves under the title of the little James VI. At home Elizabeth expected a fresh outbreak, and could not be certain that Alva would be unable to support it when it occurred. Cecil accordingly pleaded hard with her to marry the frivolous Duke of Anjou. He thought that unless she married and had children, her subjects would turn from her to Mary, who, having already a son, would give them an assured succession. If she was to marry, an alliance with the tolerant Government of France was better than any other. Elizabeth indeed consented to open negotiations for the marriage, though it was most unlikely that she would ever really make up her mind to it. The English Catholics, in consequence, flung themselves into the arms of the king of Spain, and in March =1571=, Ridolfi, a Florentine banker residing in England, who carried on their correspondence with Alva, crossed to the Netherlands to inform him that the great majority of the lay peers had invited him to send 6,000 Spanish soldiers to dethrone Elizabeth and to put Mary in her place. Norfolk, who had been released from the Tower (see p. 441), was then to become the husband of Mary, and it was hoped that there would spring from the marriage a long line of Catholic sovereigns ready to support the Papal Church. 3. =Elizabeth and the Puritans.=--Elizabeth's temporising policy had naturally strengthened the Calvinism of the Calvinistic clergy. In every generation there are some who ask not what is expedient but what is true, and the very fact that they aim at truth, in defiance of all earthly considerations, not merely assures them influence, but diffuses around them a life and vigour which would be entirely wanting if all men were content to support that which is politically or socially convenient. Such were the best of the English Puritans, so called because, though they did not insist upon the abolition of Episcopacy or the establishment of the Calvinistic discipline (see p. 431), they contended for what they called purity of worship, which meant the rejection of such rites and vestments as reminded them of what they termed the idolatry of the Roman Church. Elizabeth and Parker had from time to time interfered, and some of the Puritan leaders had been deprived of their benefices for refusing to wear the cap and surplice.
