The Popes made no pretence of hiding their claims to the legislative power. Urban II strongly affirms that it has always been in the power of the Roman Pontiff to frame new laws; and two centuries later Boniface VIII embodies in his addition to the Canon Law the words of an earlier writer, that the Roman Pontiff is considered to hold all laws in the repository of his breast. There was no room in such a theory for any effective co-operation of ecclesiastical Councils, however representative. The _Dictatus Papae_ declares that no General Council can be held without the papal command. Pascal II points out that no Council can dictate the law of the Church, because every Council comes into existence and receives its power by authority of Rome, and in its statutes the authority of the Pope is clearly not interfered with. But the Popes often found it convenient to obtain the sanction of a General Council for their legislation, and the four Lateran Councils (1123, 1139, 1179, 1215) were the occasions for great and important additions to the Canon Law. But from the time of the third Lateran Council, at all events, all ordinances of a General Council were issued in the name of the Pope, although the approval or the fact of the Council was likewise expressed. Thomas Aquinas merely expresses the recognised law of the Church when he says that the Holy Fathers gathered together in Councils can make no laws except by the intervention of the authority of the Roman Pontiff, for without that authority a Council cannot even meet. [Sidenote: Popes above law.] It followed from this assumption of the supreme legislative power that, in the first place, the Pope himself claimed not to be bound by the laws which he made. Thus in the thirteenth century papal writers denied that the Roman Church could commit simony. Certain acts are simoniacal because they have been prohibited as such by Canon Law; but inasmuch as it is the Pope who had forbidden them, the prohibition does not bind him. And in virtue of this power, from the time of Innocent IV the Popes added to their bulls a _non obstante_ clause whereby they suspended in a particular instance all laws or rights which might otherwise stand in the way of their grant.
