Although the Popes, in establishing the Inquisition, had only proposed to punish the crime of heresy, yet the inquisitors were commissioned to pursue those Christians who were only suspected, because it was the only means of discovering those who were really guilty. There were many crimes which came under the jurisdiction of a civil judge, which the Popes considered no one could be guilty of without being tainted with a false doctrine; and although they were pursued by secular tribunals, the inquisitors were enjoined to consider the accused as suspected of heresy, and to proceed against them, in order to ascertain if they committed these crimes from the depravity natural to man, or from the idea that they were not criminal; which opinion caused a suspicion that their doctrine was erroneous. A species of blasphemy which was called heretical, belonged to this class of crimes; it was committed against God or his saints, and showed in the offender erroneous opinions of the omniscience or other attributes of the Deity. It rendered the blasphemer liable to be suspected of heresy, as the inquisitor might consider it a proof that his habitual thoughts were contrary to the faith. The second species of crime which caused a suspicion of heresy, was sorcery and divination. If the offenders only made use of natural and simple means of discovering the future, such as counting the lines in the palm of the hand, they came under the jurisdiction of a civil judge; but all sorcerers were liable to be punished for heresy by the Inquisition, if they baptized a dead person, re-baptized an infant, made use of holy water, the consecrated host, the oil of extreme unction, or other things which proved contempt or abuse of the sacraments and the mysteries of religion. The same suspicion affected those who addressed themselves to demons in their superstitious practices. A third species of crime was the invocation of demons. Nicholas Eymerich informs us that, in his office of inquisitor, he had procured and burnt, after having read them, two books which treated of that subject; they both contained an account of the power of demons, and of the mode of worshipping them. The same author adds, that in his time a great number of trials for this crime took place in Catalonia, and that many of the accused had gone so far as to worship Satan, with all the signs, ceremonies, and words of the Catholic religion. A fourth kind of crime which caused suspicion of heresy, was, to remain a year, or longer, excommunicated without seeking absolution, or performing the penance which had been imposed. The Popes affirmed that no Catholic, irreproachable in his faith, could live with so much indifference under the censure of the church.
