It would be difficult to overrate the effect of this papal achievement. It may be that the Papacy stood forth as champion of innocence when policy coincided with righteousness; but it was the righteousness and not the policy which gave the Papacy strength. One can imagine, in days when brutal barons, scattered in strongholds all over the country, were the normal forms of power and authority, what effect such news had upon the people. A pilgrim from across the Alps, a peddler, or some poor vagrant, enters a village huddled at the foot of a hill, on which stands a great castle where a drunken lord revels with his mistresses, and recounts to the assembled peasants, serfs, and slaves, how the Holy Father, in the name of God, had commanded a greater lord, in a greater castle, to put away his mistress and bring back his wife, and how that lord had got down on his knees and had done the Holy Father's bidding. The second case was the victory of papal authority over the spirit of nationality in the Church. When the incipient nations of France and Germany, having separated from the Empire, had begun to be self-conscious, the spirit of nationality naturally showed itself in ecclesiastical matters as well as in political matters. There was obvious likelihood that the nations would govern themselves ecclesiastically as well as politically. Should they do so, the papal supremacy would fall just as the Imperial supremacy had fallen, and the unity of the Church would be shattered just as the Empire had been. Here was certainly a great danger to the Papacy, and probably a great danger to Christianity and civilization; at least so Nicholas thought. He resolved to meet it boldly. His opportunity came when a French (West Frankish) bishop appealed to Rome against the action of his metropolitan. The metropolitan objected that there was no precedent for papal action in such a case; he did not deny that the Pope had certain appellate functions, but said that if the Pope interfered directly in the discipline of bishops, the power of the metropolitan would be impaired. It is needless to say that this argument did not produce the result that the metropolitan desired. There was nothing the Papacy wanted more than that its central government should act directly everywhere, and that all bishops should be dependent upon Rome; that was the very principle of papal supremacy. The issue would determine whether the Papacy was to be an autocratic power, or a limited court of appeal. Nicholas was able to take advantage of the troubled political situation to enforce direct papal authority, and so added an immense prerogative to the papal power.
