62. Celibacy of the Clergy. Gregory VII, 1074.
Mansi, XX, p. 433; Corpus Juris Can., Diet. LXXXI, e. xv.
If there are any priests, deacons, or subdeacons who are married, by the power of omnipotent God and the authority of St. Peter we forbid them to enter a church until they repent and mend their ways. But if any remain with their wives, no one shall dare hear them [when they officiate in the church], because their benediction is turned into a curse, and their prayer into a sin. For the Lord says through the prophet, "I will curse your blessings" [Mal. 2:2]. Whoever shall refuse to obey this most salutary command shall be guilty of the sin of idolatry. For Samuel says: "For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry" [1 Sam. 15:23]. Whoever therefore asserts that he is a Christian but refuses to obey the apostolic see, is guilty of paganism.
63. Action of the Ninth General Council in the Lateran Against the Marriage of the Clergy, 1123 A.D.
We forbid priests, deacons, and subdeacons to live with wives or concubines, and no woman shall live with a clergyman except those who are permitted by the council of Nicæa, viz.: mother, sister, aunt, or others of such sort that no suspicion may justly arise concerning them.
64. Prohibition of Lay Investiture, November 19, 1078.
Jaffé, II, p. 332; Doeberl, III, no. 5 a.
Since we know that investitures have been made by laymen in many places, contrary to the decrees of the holy fathers, and that very many disturbances injurious to the Christian religion have thereby arisen in the church, we therefore decree: that no clergyman shall receive investiture of a bishopric, monastery, or church from the hand of the emperor, or the king, or any lay person, man or woman. And if anyone has ventured to receive such investiture, let him know that it is annulled by apostolic authority, and that he is subject to excommunication until he has made due reparation.
Until recently the _Dictatus Papæ_ was supposed to have been written by Gregory VII, but it is now known to have had a different origin. In 1087 cardinal Deusdedit published a collection of the laws of the church, which he drew from many sources, such as the actions of councils and the writings of the popes. The _Dictatus_ agrees so clearly and closely with this collection, that it must have been based on it; and so must be later than the date of its compilation, 1087. It seems evident that some one, while reading the collection of Deusdedit, wishing to formulate the papal rights and prerogatives, expressed them in these twenty-seven theses. Although they were not formulated by Gregory himself, there is no doubt that they express his chief principles.
