The Roman pontiffs having usurped a power over several churches were particularly severe on the Bohemians, which occasioned them to send two ministers and four lay-brothers to Rome, in the year 977, to obtain redress of the pope. After some delay, their request was granted, and their grievances redressed. Two things in particular they were permitted to do, viz., to have divine service performed in their own language, and to give the cup to the laity in the Sacrament.

The disputes, however, soon broke out again, the succeeding popes exerting their whole power to impose on the minds of the Bohemians; and the latter, with great spirit, aiming to preserve their religious liberties.

In A.D. 1375, some zealous friends of the Gospel applied to Charles, king of Bohemia, to call an ecumenical Council, for an inquiry into the abuses that had crept into the Church, and to make a full and thorough reformation. The king, not knowing how to proceed, sent to the pope for directions how to act; but the pontiff was so incensed at this affair that his only reply was, "Severely punish those rash and profane heretics." The monarch, accordingly banished every one who had been concerned in the application, and, to oblige the pope, laid a great number of additional restraints upon the religious liberties of the people.

The victims of persecution, however, were not so numerous in Bohemia, until after the burning of John Huss and Jerome of Prague. These two eminent reformers were condemned and executed at the instigation of the pope and his emissaries, as the reader will perceive by the following short sketches of their lives
