great reformer, John Huss, himself a priest, protesting against
the corruptions of his order. They trapped him into their power
by means of a "safe-conduct"--which they repudiated because no
promise to a heretic could have validity. They found him guilty
of having taught the hateful doctrine that a priest who committed

elevated bench by a table on which stood a coffer containing
priestly vestments. After some preliminaries, including a
sermon by the Bishop of Lodi, in which he assured Sigismund
that the events of that day would confer on him immortal
glory, the articles of which Huss was convicted were
recited. In vain he protested that he believed in
transubstantiation and in the validity of the sacrament in
polluted hands. He was ordered to hold his tongue, and on

spite of this he continued to utter protests. The sentence
was then read in the name of the council, condemning him
both for his written errors and those which had been proven
by witnesses. He was declared a pertinacious and
incorrigible heretic who did not desire to return to the
Church; his books were ordered to be burned, and himself to
be degraded from the priesthood and abandoned to the secular
