IN May 1622 a series of private discussions on religion was held in London between representatives of the Anglican Church and the Jesuit, John Percy, alias Fisher. The occasion was the announcement by the Countess of Buckingham, mother of King James I’s favourite, George Villiers, Marquess (later Duke) of Buckingham, of her intention to become a Catholic. The King and the Marquess arranged the discussions which occupied three successive days, the 24th, 25th and 26th of May. Two eminent Anglican divines were enlisted to debate with Percy. On the first day the Anglican case was argued by Francis White, at this time a royal chaplain and later a bishop. He was opposed by Percy, in the presence of the Countess, the Marquess and Marchioness (Lady Catherine, who had also influenced her husband's decision to hold these discussions by declaring her intention to return to the Catholic faith in which she had been brought up), Bishop John Williams, (the Lord Keeper), and—possibly—the King. On the second day the King himself took the leading part in putting the Anglican case. On the third day the chief Anglican protagonist was William Laud, at this period Bishop of St. David's, who took the place of Francis White.
