Schism was the sixth case where heresy was suspected. It may exist either without heresy or with it. To the first class belong all schismatics, who admit the articles of the faith, but deny the authority of the Pope, as head of the Catholic Church, and vicar of Jesus Christ. The second is composed of those who hold the same opinions as the first, and also refuse to believe in some of the articles; such as the Greeks, who hold that the Holy Ghost proceeds only from the Father, and not from the Son. The Inquisition also proceeded against concealers, favourers, and adherents of heretics, as being suspected of professing the same opinions. The seventh class was composed of all those who opposed the Inquisition, and prevented the inquisitors from exercising their functions. The eighth class comprehended those nobles who refused to take an oath to drive the heretics from their states. The ninth class consisted of governors of kingdoms, provinces and towns, who did not defend the Church against heretics, when they were required by the Inquisition. The tenth class comprised those who refused to repeal the statutes in force in towns and cities, when they were contrary to the measures decreed by the holy office. The eleventh class of suspected persons, were all lawyers, notaries, and other persons belonging to the law, who assisted heretics by their advice; or concealed papers, records, and other writings, which might make their errors, dwellings, or stations known. In the twelfth class of suspected were those persons who have given ecclesiastical sepulture to known heretics. Those who refused to take an oath in the trials of heretics when they were required to do it, were also liable to suspicion. The fourteenth class were deceased persons who had been denounced as heretics. The Popes, in order to render heresy more odious, had decreed that the bodies of dead heretics should be disinterred and burnt, their property confiscated, and their memory pronounced infamous. The same suspicion fell upon writings which contained heretical doctrines, or which might lead to them. Lastly, the Jews and Moors were considered as subject to the holy office, when they engaged Catholics to embrace their faith, either by their writings or discourse. Although all the persons guilty of the crimes above-mentioned were under the jurisdiction of the holy office, yet the Pope, his legates, his nuncios, his officers, and familiars were exempt; and if any of these were denounced as heretics, the inquisitor could only take the secret information and refer it to the Pope. Bishops were also exempt, but kings had not that privilege.
