Pseudo.lsidorian Decretals Help Papacy
NICOLAS, I, 858-67, greatest Pope between Gregory I and GregoryVII. First Pope to wear a Crown, To promote his claim of universal authority he used with great effect the “PSEUDO-ISIDORIAN-DECRETALS,” a book that appeared about 857, containing documents that purported to be letters and decrees of bishops and councils of the 2nd end 3rd centuries, all tending to exalt the power of the Pope. They were deliberate forgeries and corruptions of ancient historical documents, but their spurious character was not discovered till some centuries later. Whether Nicolas knew them to be forgeries, at least he lied in stating that they had been kept in the archives of the Roman Church from ancient times. But they served their purpose in “stamping the claims of the medieval priesthood with the authority of antiquity.” “The Papacy, which was the growth of several centuries, was made to appear as something complete and unchangeable from the very beginning.” They included the “Donation of Constantine,” which represented him as giving the Roman Bishop the Western Provinces with all the imperial insignia. “The objective was to ante-date by 5 centuries the Pope’s Temporal Power, which in fact rested on the donations of Pepin and Charlemagne.” The most colossal literary fraud in history.” ” It strengthened the Papacy more than any other one agency, and forms to large extent the basis of the canon law of the Roman Church.”
