But this was not all. Next, the King was embroiled in a great number of ways. The more extreme of his Protestant subjects feared and hated the Catholic Church as much as good Catholics hate and fear the Devil; and although for the present our people had great liberty both at Court and elsewhere, no man could tell when that liberty might be curtailed. And, indeed, it had been to a great part already curtailed five years before by the Test Act, forbidding the Catholics to hold any high place at the Court or elsewhere, though this was largely evaded. There was even a movement among some of them, and among the most important of them too, in the House of Lords and elsewhere, to exclude the Duke of York from the succession; and they advanced amongst themselves in support of this the fear that a French army might be brought in to subdue England to the Church. And, worst of all, as I had learned privately in Rome, there was some substance in their fear, though few else knew it; since the King was in private treaty with Louis for this very purpose. Again, a further embroilment lay in the propositions that had been made privately to the King that he should rid himself of his Queen—Catherine—on the pretext that she had borne no child to him, and could not, and marry instead some Protestant princess. Lastly, and most important of all, so greatly was Charles turned towards the Church, that he had begged more than once, and again lately, that a priest might be sent to him to be always at hand, in the event of his sudden sickness, whom none else knew to be a priest; and it was this last matter, I think, that had determined the Holy Father to let me go, as I had wished, though I was no priest, to see how the King would bear himself to me; and then, perhaps afterwards, a priest might be sent as he desired.
This then was the mission on which I was come to London.
I was to present myself at Court and place myself at His Majesty’s disposal. The letters that I carried were no more than such as any gentleman might bring with him; but the King had been told beforehand who I was, and that I was come to be a messenger or a go-between if he so wished, with him and Rome. So much the King was told, and the Duke. But on my side I was told a little more—that I was to do my utmost, if the King were pleased with me, to further his conversion and his declaration of himself as a Catholic; that I was to mix with all kinds of folks, and observe what men really thought of all such matters as these, and send my reports regularly to Rome; that I was to place myself at the King’s service in any way that I could—in short that I was to follow my discretion and do, as a layman may sometimes even more than a priest, all that was in my power for the furtherance of the Catholic cause.
