In Cena Domini, a celebrated papal bull, so called from the ancient day of its annual publication, Holy Thursday. It is not, as other bulls, the work of a single pope, but, with additions and modifications at various times, dates back to the middle ages. Its present form, however, it received from the popes Julius II., Paul III., and finally Urban VIII., in 1627, from which year it continued for a century and a half to be published annually on Holy Thursday. It may be briefly described as a summary of ecclesiastical censures, especially of those with which grievous violation of the faith of the church, or of the rights of the church or of the Roman see, are visited; excommunication being denounced against heresy, schism, sacrilege, usurpation of the rights of the church or of the pope, forcible and unlawful seizure of church property, personal violence against ecclesiastics, &c. The bull also denounces other crimes, as piracy, plunder of shipwrecked goods, and forgery. This bull, being regarded by most of the crowned heads of Europe as an infringement of their rights, encountered in the 17th century the determined opposition of nearly all the courts, even the most Catholic; and at length, in 1770, Clement XIV. discontinued its publication, which has never since been renewed.
