For this attendance at court he had to pay the penalty of being suspected a Papist. At his very first public discussion with Vincent, the nickname Jesuit had been given him and had stuck to him ever after. The Quakers were many of them branded with the same opprobrious name. In the case of Barclay, there was his early training and boyish conversion to Romanism, and the fact that many of his family were Catholics, to give plausibility to the charge. As to the body at large, "it was believed that the doctrine of the inner light was taught by Jesuit, and that a Franciscan friar had said no churches came so near his own as the Quakers."[11] The Friends could not accept the ordinary teaching of the supremacy of the Bible as a rule of faith, and sometimes on this point their destructive criticism was welcome to Catholics but galling to Protestants. Then they could not take the oath of allegiance and supremacy. So the popular charge was not without some plausible though utterly delusive pretexts.
[11] Penn himself writes "There is a people called 'the silent' or 'people of rest' in Italy, at Naples and at Rome itself, that come near Friends; an inward people from all ceremonies and self-worship, [he means worship unprompted and unaided by the Holy Spirit,] seekers, the Pope and two cardinals favour them. A poor Spanish Friar, called Molino, is the first of them. A thousand in Naples it is thought."--DR. STOUGHTON'S LIFE, p. 228.
Now the impression that Penn was a Jesuit at heart, in spite of his Quaker dress and profession, gained ground fast. Tillotson had his fears that the charge was true, and said so; but on Penn assuring him that there was no truth in the charge, he fully and honourably apologised. But for long the suspicion clung to Penn and would not be cast off. That he was determined in all things to keep a clear conscience at all costs is manifest from his conduct in connection with James' efforts to secure Magdalen College, Oxford, for one of his tools. Penn had several times before strained his favour with the king to the last point of endurance, until in one instance the king threatened to turn him out of the room. In this case he wrote a letter so bold and uncompromising as to fill us with amazement. He calls the act one which could not in justice be defended. Such mandates as the king addressed to the fellows he calls a force to conscience and not very agreeable to his other gracious indulgences. Yet because in this matter Penn at first, before he fully understood the case, thought some concessions might be made by the College, Macaulay charges him with simony of the very worst kind. The only other ground for such a charge is the jesting remark of Penn to the deputation that waited on him at Windsor. "If the Bishop of Oxford die, Dr. Hough may be made bishop. What think you of that, gentlemen?" This might have been understood as a hint that, if Dr. Hough would withdraw his opposition, it might be better for him, _if it had not been for Dr. Hough's own words_. But whatever Penn may have said in jest (possibly not wisely) we should remember that Dr. Hough after the interview thanked God that _he did not hint at a compromise_.
