After his defeat, Charles indicated to the remaining supporters of the Jacobite cause in England that, accepting the impossibility of his recovering the English and Scots crowns while he remained a Roman Catholic, he was willing to commit himself to reigning as a Protestant. Accordingly, he visited London incognito in 1750 and conformed to the Protestant faith by receiving Anglican communion, likely at one of the remaining non-juring chapels. Bishop Robert Gordon, a staunch Jacobite whose house in Theobald's Row was one of Charles's safe-houses for the visit, is the most likely to have celebrated the communion, and a chapel in Gray's Inn was suggested as the venue as early as 1788 ["Gentleman's Magazine", 1788]. This rebutted David Hume's suggestion that it was a church in the Strand. Unusually, the news of this conversion was not advertised widely, and Charles had seemingly returned to the Roman Catholic faith by the time of his marriage.
