Marsi, and besides the city of Teramne. (12) All the aforesaid provinces, cities, towns, fortresses, villages, territories, and patrimonies, we now grant to thee, St. Peter, and through thee to thy vicar, our spiritual father, pope John, and his successors to the end of the world, for the salvation of our own soul and the souls of our son, our parents, and our successors, and for the preservation of the whole Frankish people; and we grant them in such a way that the popes shall possess them in their own right and government and control. (13) Likewise, by this agreement we confirm all the gifts which king Pippin and emperor Karl voluntarily gave to St. Peter, the apostle, and also the rents and payments and taxes which were paid annually to the king of the Lombards from Tuscany and the duchy of Spoleto, as is contained in the aforesaid donation and as was agreed upon between pope Adrian of blessed memory and the emperor Karl, when the same pope surrendered to the emperor his claims on the provinces of Tuscany and Spoleto on condition that the aforesaid taxes should be paid each year to the church of St. Peter, the apostle. But in all this our authority over these provinces and their subjection to us and to our son are not in any way diminished. (14) We therefore confirm your possession of all the things mentioned above in this document; they shall remain in your right and ownership and control, and no one of our successors shall on any pretext take from you any part of the aforesaid provinces, cities, towns, fortresses, villages, dependencies, territories, patrimonies, or taxes, or lessen your authority over them. We will never do so, nor allow others to do so, but we will always defend the church of St. Peter and the popes who rule over that church in their possession of all these things, as far as in us lies, that the popes may be able to keep these things in their control to use, enjoy, and dispose of. (15) In all this there shall be no derogation of our power or of the power of our son and our successors. 55. Leo VIII Grants the Emperor the Right to Choose the Pope and Invest all Bishops, 963. Cor. Jur. Can., Dist. LXIII, c. xxiii; Migne, 134, cols. 992 ff. Otto I, after the rebellion of John XII, deposed him and caused a layman to be made pope, who took the title Leo VIII. The new pope then issued a decree, the essence of which is contained in the following document. It shows how determined Otto was to assert his imperial authority and is important as a statement of the imperial theory. Leo VIII is regarded as an anti-pope by the Roman church, because, according to the papal theory, Otto had no power to depose a pope. John XII was the legal pope and there could be no other until he died.
