Again Wycliffe was called to defend the rights of the English crown against the encroachments of Rome; and being appointed a royal ambassador, he spent two years in the Netherlands, in conference with the commissioners of the pope.
Here he was brought into communication with ecclesiastics from France, Italy, and Spain, and he had an opportunity to look behind the scenes and gain a knowledge of many things which would have remained hidden from him in England. He learned much that was to give point to his after labors. In these representatives from the papal court he read the true character and aims of the hierarchy. He returned to England to repeat his former teachings more openly and with greater zeal, declaring that covetousness, pride, and deception were the gods of Rome.
In one of his tracts he said, speaking of the pope and his collectors: "They draw out of our land poor men's livelihood, and many thousand marks, by the year, of the king's money, for sacraments and spiritual things, that is cursed heresy of simony, and maketh all Christendom assent and maintain this heresy. And certes though our realm had a huge hill of gold, and never other man took thereof but only this proud worldly priest's collector, by process of time this hill must be spended; for he taketh ever money out of our land, and sendeth nought again but God's curse for his simony." -- John Lewis, History of the Life and Sufferings of J. Wiclif, page 37.
