In 1376 Parliament renewed its assault on pontifical pretensions and exactions; and there was cause, since twenty thousand marks, or pounds, were sent annually to Rome from the Pope's collector in England, which collector was a Frenchman,--another indignity. Against these corruptions and usurpations Wyclif was unsparing in his denunciations; and the hierarchy at last were compelled, by their allegiance to Rome, to take measures to silence and punish him as a pertinacious heretic. The term "heretic" meant in those days opposition to papal authority, as much as opposition to the theological dogmas of the Church; and the brand of heresy was the greatest stigma which authority could impose. The bold denunciator of papal abuses was now in danger. He was summoned by the convocation to appear in Saint Paul's Cathedral and answer for his heresies, on which occasion were present the Archbishop of Canterbury and the arrogant Bishop of London,--the latter the son of the Earl of Devonshire, of the great family of the Courtenays. Wyclif was attended by the Duke of Lancaster and the Earl Marshal,--Henry Percy, the ancestor of the Dukes of Northumberland,--who forced themselves into the Lady's chapel, behind the high altar, where the prelates were assembled. An uproar followed from this unusual intrusion of the two most powerful men of the kingdom into the very sanctuary of prelatic authority. What could be done when the great Oxford professor--the most learned Scholastic of the kingdom--was protected by a royal duke clothed with viceregal power, and the Earl Marshal armed with the sword of State?
