This protector he found in John of Gaunt, Duke of Lancaster, who, next to the King, had the greatest authority in England. It is probable that Wyclif enjoyed at Bruges the friendship of this great man (great for his station, influence, and birth, at least), who was at the head of the opposition to the papal claims,--resisted not only by him, but by Parliament, which seems to have been composed of men in advance of their age. As early as 1371 this Parliament had petitioned the King to exclude all ecclesiastics from the great offices of State, held almost exclusively by them as the most able and learned people of the realm. From the time of Alfred this custom had not been seriously opposed by the baronial lords, who were ignorant and unenlightened; but in the fourteenth century light had broken in upon the darkness: the day had at least dawned, and the absurdity of confining the cares of State and temporal matters to men who ought to be absorbed with spiritual duties alone was seen by the more enlightened of the laity. But the King was not then prepared to part with the most efficient of his ministers because they happened to be ecclesiastics, and the custom continued for nearly two centuries longer. Bishop Williams was the last of the clergy who filled the great office of chancellor, and Archbishop Laud was the last of the clergy who became a prime minister. The reign of Elizabeth was marked, for the first time in the history of England, by the almost total exclusion of prelates from great secular offices. In the reign of Edward III. it was William of Wykeham, Bishop of Winchester, who held the great seal, and the Bishop of Exeter who was lord treasurer,--probably the two men in the whole realm who were the most experienced in public affairs as men of business. Wyclif, it would appear, although he was an ecclesiastic, here took the side of Parliament against his own order. In his treatise on the "Regimen of the Church" he contends that neither doctors nor deacons should hold secular offices, or even be land stewards and clerks of account, and appeals to the authority of the Fathers and Saint Paul in confirmation of his views. At this time he was a doctor of divinity and professor of theology in the University, having been promoted to this high position in 1372, two years before he was sent as commissioner to Bruges. In 1375, he was presented to the rectory of Lutterworth in Leicestershire by the Crown, in reward for his services as an ambassador.
