It is not improbable that the exaggerated fears of the people, on the one hand, and the expectations of the Catholics, on the other, may have alarmed Charles, who was firmly attached to the Church of England. Upon an application being made to Pope Gregory the XV. to grant a dispensation for the marriage, that Pontiff had replied in a Latin letter, expressing, first, his regret at the altered state of Britain;[104] next, his hopes that, as under his predecessor, Gregory the Great, Apostolical authority had been there established, he might be permitted to see it reestablished by the conversion of the Prince, “the flower of the Christian world,” who had proved, by seeking a Catholic Princess, that he did not hate the see of Rome. He then set before the Prince the example of his Highness’s ancestors, and concluded with hoping that Charles would become “the infranshiser of Brittayne.” Footnote 104: State Papers, vol. clxiii., No. 59.--April 10, 1623. Several Catholics who had worn a mask of Protestantism now threw it off, and in hopes of toleration, avowed themselves Romanists; amongst these were Sir John Wentworth and Lord Vaughan. “Everyone,” Lady Hatton wrote to Carleton, “was on the wing for Spain;” but, “in spite of her walks and talks with Gondomar,” she would ever, she said, oppose his country.[105] Footnote 105: Ibid, vol. clxiii., No. 2. Nor were the Catholics without reason in their dreams of enjoying a degree of security and toleration long most unjustly and cruelly withheld. Even after James had begun to listen to the changed tone adopted by Buckingham, preparations had been going on, both for the reception and maintenance of the Infanta, which might well afford hopes of religious liberty. It was reported that the marriage conditions were to be, the liberation of the Catholics and the abandonment of the Hollanders. The Spanish ambassador surveyed Denmark House and St. James’s, where “lodgings,” as they were styled, were prepared for the Infanta. At each place, he ordered a new chapel, and Inigo Jones was to prepare each with great costliness. The Spanish ambassador laid the stone of a new chapel for the Infanta at St. James’s, whilst the Savoy chapel was to be given up to the Infanta’s suite.
