But before this decision of the Crown was made, the services of Wyclif had been accepted by the Parliament in its resistance to the claim which Pope Urban V. had made in 1366, to the arrears of tribute due under John's vassalage. Edward III. had referred this claim to Parliament, and the Parliament had rejected it without hesitation on the ground that John had no power to bind the realm without its consent. The Parliament was the mere mouthpiece of Wyclif, who was now actively engaged in political life, and probably, as Dr. Lechler thinks, had a seat in Parliament. He was, at any rate, a very prominent political character; for he was sent in 1374 to Bruges, as one of the commissioners to treat with the representatives of the French pope in reference to the appointment of foreigners to the rich benefices of the Church in England, which gave great offence to the liberal and popular party in England,--for there was such a progressive party as early as the fourteenth century, although it did not go by that name, and was not organized as parties are now. In fact, in all ages and countries there are some men who are before their contemporaries. The great grievance of which the more advanced and enlightened complained was the interference of the Pope with ecclesiastical livings in England. Wyclif led the opposition to this usurpation; and this opposition to the Pope on the part of a churchman made it necessary for him to have a protector powerful enough to shield him from papal vengeance.
