But Pius was far from abandoning his hopes. After ten years suspension he had again summoned the Council of Trent. The cry for Church reform, the threat of national synods in Spain and in France, forced this measure on the Pope; and Pius availed himself of the assembly of the Council to make a fresh attempt to turn the tide of the Reformation and to win back the Protestant Churches to Catholicism. He called therefore on the Lutheran princes of Germany to send doctors to the Council, and in May 1561, eight months after Parpaglia's failure, despatched a fresh nuncio, Martinengo, to invite Elizabeth to send ambassadors to Trent. Philip pressed for the nuncio's admission to the realm. His hopes of the Queen's return to the faith were now being fed by a new marriage-negotiation; for on the withdrawal of the Archduke of Austria in sheer weariness of Elizabeth's treachery, she had encouraged her old playfellow, Lord Robert Dudley, to hope for her hand and to amuse Philip by pledges of bringing back "the religion," should the help of the Spanish king enable him to win it. Philip gave his help, but Dudley remained a suitor, and the hopes of a Catholic revolution became fainter than ever. The Queen would suffer no landing of a legate in her realm. The invitation to the Council fared no better. The Lutheran states of North Germany had already refused to attend. The Council, they held, was no longer a council of reunion. In its earlier session it had formally condemned the very doctrine on which Protestantism was based; and to join it now would simply be to undo all that Luther had done. Elizabeth showed as little hesitation. The hour of her triumph, when a Calvinistic Scotland and a Calvinistic France proved the mainstays of her policy, was no hour of submission to the Papacy. In spite of Philip's entreaties she refused to send envoys to what was not "a free Christian Council." The refusal was decisive in marking Elizabeth's position. The long period of hesitation, of drift, was over. All chance of submission to the Papacy was at an end. In joining the Lutheran states in their rejection of this Council, England had definitely ranged itself on the side of the Reformation.
